When And How To Harvest Marijuana Plants

When And How To Harvest Marijuana Plants

Harvesting marijuana is a bit like harvesting grapes (or other fruits). The longer you wait, the more potent the grape is and the stronger the alcohol. With marijuana, the longer you wait, the more cannabinoids there will be --, and that means a stronger product.

The timing of the harvest is often one of the trickiest parts for new marijuana growers. Harvesting early will reduce the potency and effects of the marijuana, while harvesting late will make it have a narcotic effect with a too-strong taste.

In this article, we are going to look into the various ways of knowing exactly when to harvest. I’ll describe how to harvest by flowering time, the pistil colors, and the resin colors. We’ll also explain what to expect during the harvest process.

When to harvest

After your plant has gone through its flowering phase, it will begin to slide into a decline in health. There are a number of different symptoms which can flag this for you. You’ll notice that the pistils of the cannabis plant are turning red.

The stem might begin to broaden. Any resin on the buds will begin to brown and darken, and the leaves of the plant will start to yellow and die back. If your plant has flowered and you begin to notice any of these symptoms occur, chances are good that you are ready to harvest!

There’s some contention between growers on the precise ‘best’ time to harvest your cannabis. It depends in part on your own personal tastes. It’s not so different from harvesting other plants, even fruits or vegetables.

There are different ways to determine when it's time to harvest. I'll explain all of the methods further on in this article but here's a quick overview:

Flowering time
Indica: harvest after 8 weeks of flowering
Sativa: harvest after 10 weeks of flowering
Autoflower: 10 weeks from seedling to bud

50-70% brown - young, light marijuana
70-90% brown - ripe, heavy marijuana
90-100% brown - sharp, heavy marijuana

Clear trichomes - wait a bit longer
Milky white/amber trichomes - ready for harvest
All Amber trichomes - overripe

The best way to be able to properly see if your plants are ready for harvest is to use a magnifying tool of some sort. You should be looking for trichomes in your buds that are glittery and filled with resin. If you are seeing them this way, you will be able to harvest at the perfect time.

Magnifying tools for harvesting

Magnifying Tools
There are a number of different kinds of magnifying tools you can use to look more closely at your plants. Each will get the job done, but like with any aspect of growing and harvesting your marijuana plants, you need to understand what they all do and what the best tool for you is.

Jewelers Loupe
A Jewelers Loupe is perfect for someone working on a budget. It’s not very high-tech, making it the least helpful in seeing the details for the stage of life your buds are in. That being said, it should give you enough information to identify if it is harvest time yet or not.

Handheld Magnifier
More powerful than a jewelers loupe, a handheld magnifier of some sort will zoom in enough to give you an even better idea of your buds’ status. Such high magnification can cause some problems, however, since sometimes it makes it difficult for you to focus.

Digital Microscope
If you’re someone who likes state-of-the-art technology, this might be the route for you. It’s more expensive, as these types of technologies always are, but it will give you a black-and-white answer to your question: Are my plants ready for harvest? You just need to connect it to your laptop to see the information at hand. You should read up on the methods of using it before purchasing one of these.

Digital Microscope cannabis

The latest possible harvest will net you the best results, but with cannabis, that can mean an overpowering and unpleasant flavor if you wait too long. The color of the pistils is the most common way for growers to determine when they want to harvest their plants and begin processing them for use.

Some growers harvest as soon as the pistils begin to turn red. Others wait until the pistils are almost entirely red and the resin of the plant is dark. In general, the later you harvest, the more you will get, but it is also likely to have a stronger flavor. If you wait too long, you could see decreased effectiveness of the active ingredients.

The right color of the pistils

Besides the color of the pistils, examining the resin on your flowering plants is probably the best way to know if they’re ready for harvest. You will notice that the glands covered in resin become enlarged when the plant is mature, and they will also start to swell and look deformed.

The resin will darken from transparent to opaque amber as it becomes more mature. When the resin is still sticky and transparent, the plant is ready to be harvest. Once that resin darkens and becomes more amber-hued, you should make sure to harvest quickly because the plant will go through a deterioration of active ingredients.

Harvesting based on flowering time

One way to decide when to harvest is to simply base it off of timing. This timing can vary according to the specific strain that you are growing, so it’s important to read the descriptions and the comment sections of any online posts about your strain.

Note that the conditions in your grow room or outdoor climate also plays a role in the development of your plant. This is no accurate way of deciding when it's time to harvest but it gives a an idea. There are a few rules of thumb you can stick with:


If you are growing an indica plant, you can expect the flowering time to last about eight weeks before the proper harvesting time. For outdoor growers, you can expect the best harvesting time to be around the end of September.

Indica vs Sativa buds

Indica vs Sativa


For sativa plants, the flowering periods lasts for about a month longer than indicas, meaning it will take about 12 weeks. That being said, several haze strains will actually flower faster -- more like 9 to 10 weeks long. Check the seeds that you ordered online to be sure. Normally sativas will be ready for harvest at the end of October.


Autoflowering strains of marijuana don’t stick to any specific lighting changes, so in one way it is easier to predict because it is based solely on time. Once the first seedlings are visible above the soil, you can expect the harvest to be ready in 10 weeks.

While harvesting based on flowering time is not an exact science, it can be a good jumping off point for figuring out when exactly to harvest your marijuana plants. It also works well for planning ahead because you can see what your growing season will look like.

Red or brown pistils

This is the best and easiest method for deciding when to harvest your marijuana. Check a bud’s pistils to see what their coloring looks like -- if they’re mostly white, it is too early to harvest. If they’re all brown or red, then you missed the peak time to harvest and should do it right away before the quality of the marijuana lowers any further.

Almost ready for harvest

The pistils should be exactly right, as follows:

Harvesting brown pistils

if 0-49% of the pistils are brown, the weed is not ready yet


Harvesting based on pistils

if 50-75% of the pistils are brown, the harvest time has come but it is still early, making it best for a lighter taste and mellower high. Waiting might be your best option

Pistils when to harvest

Once 70-90% of the pistils are brown, you can harvest your marijuana plants because they are as strong and heavy as they ever will be

harvesting overripe all pistils brown

When 90-100% of the pistils brown you're almost too late for harvest. Taste is heavy and the effect is narcotic. Harvest right away and don’t wait any longer

Basically, once the pistils are ⅔ brown or a bit more, then you can safely harvest. Some new growers opt to harvest their plants at different times so they can figure out exactly when is best for their personal preferences. Some people prefer earlier harvested marijuana that has more uplifting, lighter effects, while others prefer as potent as possible.

Red or brown pistils

Red or brown pistils

When you choose to harvest will also affect the qualities of the bud. Harvesting earlier will give the plant a more stimulating effect when the ingredients are activated, while harvesting at peak ripeness will offer a more numbing hazy effect. This is another area where it comes down to personal taste. To figure out where you stand on the matter, a good bet is to harvest some of your plants early and some late. That way you can decide for yourself which is a better fit for your style as a grower.

Watch the trichomes

There is a third method of identifying whether your plants are ready to be harvested or not, in case the pistil method isn’t quite working for you. The trichome method is actually considered the more accurate one, so read carefully for it to truly benefit your judgment around harvest time.

 trichomes cannabis

Clear trichomes

The concept is simple: you simply need to take a look at the trichomes on your plants’ buds to be able to establish whether or not they are ready for harvest. Trichomes are the growths that resemble mushrooms in shape. Some trichomes are known as resin glands, which have a crystalline structure or appear frosty as they grow on the leaves and buds of your plants. If you have ever noticed the stickiness of weed, this is also responsible for that texture.

The trichomes you need to be paying close attention to are the ones that have a little ball on top of them since that is where much of the THC and other fun chemicals are housed. The key is being able to determine when they are at their highest THC level, so when is the peak time for harvesting them. Since it’s difficult to see with the naked eye, you should use one of the magnifying tools listed above to get a closer look.

Ttrichome explenation weed

Ttrichome explanation

So when do you know that the trichomes are ready? You need to compare them with the following color and texture rules:

Clear, White Hairs
This is definitely not the time to harvest. If the trichomes are clear, they won’t be potent enough for harvest, and your final yield will suffer because of it. You should wait until nearly half of the hairs are darker in color and are no longer sticking out so straight.

Half Clear or Cloudy Trichomes
It is still rather early for a harvest. The buds have not reached their full-size potential, although they will still produce a high if you harvest them now. This type of high will most likely be more energetic or “speedy.” The strain’s odor will develop further if you wait to harvest.

Mostly Cloudy Trichomes
Congratulations, you have reached the perfect stage for harvesting your buds! This is the point when they have the highest levels of THC, so if you want to maximize your yield outcome then you have to act fast. You will know your plants have reached this stage when 50 to 70 percent of the hairs have darkened from their original white color. Because of this peak amount of potency, the high that comes with the buds harvested at this time will give you some serious euphoria and will even relieve pain. This can be considered the most “intense” high you can get.

Tip: make sure to download my free Grow Bible for more information about trichomes

Amber and Cloudy Trichomes
This is a bit later than the absolute peak time for the greatest amount of potency, but only because the buds have slightly less THC and more CBN. If you are looking for a more relaxing, anxiety-reducing high, then this could actually be the perfect time for you to harvest. This high is more narcotic and often results in a “couchlock” result. You will be able to identify this stage when 70 to 90 percent of all the hairs have darkened.

You can look even more into the effects of harvesting your buds slightly earlier and later, depending on the exact type of high you are looking for. You can even harvest some during the peak time and some later, giving you a variety of options. Just make sure to label correctly so you don’t find yourself extremely relaxed when you were looking for a more energetic effect.

How to harvest

First, remove the lamp from your grow room and hang some wire from the ceiling. Then, cut the plant from the very base, then secure it (upside-down) from the wire you just hung. Turn on a fan and aim it right beneath the buds, keeping the humidity around 45% and the temperature around 64 degrees Fahrenheit. Make sure the room is dark, and the extractor fan is running.

You’ll want a heavy duty shears or scissors to handle the thickness of the plant matter, and a dish of isopropyl alcohol on hand so that you can clean sticky resin off of your scissors and hands. You’re best off wearing gloves for the cutting process, it can get pretty gooey.

The basic idea is that the moisture needs to evaporate from the plant matter while the chlorophyll in the plant breaks down. You don’t want to dry the plants too quickly because it will mean there being some chlorophyll left, which negatively alters the taste of your weed. That is why you keep the room dark and the temperature moderate.

You can expect the drying process to last somewhere between 10 and 14 days. You should keep a close eye on your plants as they are drying, making sure that no mold is growing or developing. The humidity needs to stay low for this reason. Maintain the temperature as well.

Outdoor harvesting

The harvest is another crucial stage in your plants’ lives; in some ways, it’s the most important of all. The harvest makes or breaks your end result, making it the deciding factor of whether or not your entire growing season will be considered a success.

You would be making a serious mistake if you planned on going into the harvesting time without doing the proper amounts of research ahead of time.

You need to understand the seasons and the sun, your personal security, what to do to prepare for the harvest, and what exactly happens during the flowering period. Read on to gain a better understanding of these elements of the all-important harvest.

Change of seasons

Throughout your cannabis plants’ lives, you have been monitoring a fundamental tool for measuring energy intake and time: the sun. It is the most consistent and important element of any kind of gardening.

It will be equally important at the end of your plants’ lives as it was at the beginning. Once the summer is coming to a close, you should start to again keep track of the sun and the amount of light that it is providing to your cannabis plants.

Sun important cannabis plant

Fundamental for your plant, the sun!

During the middle of the summer, your plants are probably receiving 14 hours or more of sunlight. In the northern hemisphere, the turning of August to September is around the time that the amount of sunlight decreases dramatically.

For instance, within the month of September the loss of as much as 90 minutes of sunlight per day can be expected. This is exactly the change that causes your marijuana plants to change their energy focus to flowering instead of vegetation.

If you remember, the process of sex selection involved manipulating amounts of light in order to trick mature cannabis plants to begin flowering. This strong reaction in the plants is no accident; all plants have the strong ability to distinguish day from night. So when summer turns to fall and there are only 12 or 13 hours of daylight per day, the flowering process initiates within days.

Tip: make sure to download my free Grow Bible for more information about harvest time

Because of this sensitive reaction in marijuana plants, you can manipulate them fairly easily so that they start to produce buds exactly when you want them to. They react this way to artificial lights the same way they would the natural sunlight.

This sensitivity is also why you should never plant your marijuana plants in a location that is exposed to any street lights or other artificial lights. They require properly dark nights, just as they would experience in nature during the fall.

This is why growing marijuana is the easiest in a place that has four distinct seasons. If you decide to grow cannabis, you will soon see that fall is your favorite time of year. For more details on growing outdoors you can also read this article from Howtogrowmarijuana.

Are you prepared to harvest?

When this time rolls around, you will probably have been looking forward to the harvesting time for months already. You have managed to keep your plants happy, healthy, and secure during the whole season, and now you can reward yourself with a high yield and a good harvest.

Just like with any other step in the process of growing marijuana, there are a few tricks to harvesting successfully.

prepared to harvest

Prepare yourself to harvest

You need to keep an eye out for very specific signs, and you need to know which potential mistakes are best avoided. The last thing you want is to ruin everything from a silly mistake after getting through a full season of growing.

The first most important element in successfully harvesting your plants is making sure the timing is right. This requires a careful monitoring of both the weather and your plants.

If you are feeling eager and harvest too early, the potency as well as the yield could be greatly reduced. If you are too hesitant and wait until after the plants’ peak time to harvest, the potency will begin to degrade as well.

This is why it is important to keep a close eye on the details to determine when your plants are at the perfect harvesting time. In order to know exactly when to do it, you will need to have a very thorough understanding of the flowering period’s rhythm. When in doubt, be more patient.

As soon as the flowering phase has begun, start paying attention to the sun’s timing and strength as it correlates with the seasonal changes. Use this as your means of understanding when the best time for harvesting is.

You should also look at the plant itself for signs of being ready for harvesting. You should also know the weather forecast pretty well, as the weather conditions of the actual day of harvest are also crucial.

Before harvesting, you should know how exactly you are going to go about it. It will always include cutting and moving your plants, but will you move the entire plant or cut them while they are at their growing site? How will you transport them? These questions are generally a matter of security.

You can place the plants or cuttings in sealed bags so that the odor isn’t noticeable within your car. You should consider having a friend drive the route with you shortly behind, making sure the whole way is safe. You should have your drying room ready to go before you harvest your plants so you can safely begin to dry them as soon as you are there.

When to harvest outdoors

The best sign that you're ready to harvest bud will be apparent all over the marijuana plant in the leaves and the buds themselves. The physical characteristics of the plant will change considerably.

The larger leaves will turn a yellow-brown color which tells you that the marijuana plant is dying. The stigmas of mature plants will wither at the base of the buds, while remaining a healthy white color on top.

yellow-brown color weed harvest

The yellow-brown color leaves shows it's time to harvest

Another sign, and one in which there is a bit of latitude, is in the color of the marijuana buds themselves. It is a good idea to pick them at the first sign that they are losing their rich green color. If they turn brown, a sign that they've withered a bit, the buds will smoke more harshly.

The one benefit to waiting until you near this point is that the resin glands will contain more resin, and some people don't mind the harsher smoke since they bargain that they are receiving a stronger, more intense high. This is a personal decision and one that you'll learn more about over your successive harvests.

The changing hours of the sunlight are of course the most important aspect of your marijuana plants' lives. Plants are naturally in tune to the changing amounts of light and darkness that they are receiving, and the increasingly longer hours of darkness sends a signal to a plant that it must mature.

Depending on where you grew your marijuana plants, and whether or not they were started indoors and then replanted, the sun will be the most important predictor in knowing that harvest is approaching.

Some cannabis growers, like those in many parts of Australia, Hawaii, and the southern parts of North America, can often get two or more harvests a year, because the sun provides plenty of light throughout the year. In that case, the marijuana plants will grow large, flower as if to reproduce naturally and then begin again. But since they are already quite large, and have plenty of leaves to catch the sunlight, the second harvest occurs in much less time than did the first.

For the rest of us though, cannabis growers in areas in which it is important to have your marijuana plants removed by the end of summer and the onset of the first frost, the sun is a lifeline to our finished product. The middle of the summer, which in the Northern Hemisphere falls on the 21st of June, has as much as 15 hours of sunshine.

Marijuana plants will not typically flower unless they receive at least 12 hours of darkness a day. Indoor cannabis growers are typically able to harvest more often because they control the light.

12 hours darkness and 12 hours sun

12 hours darkness and 12 hours sun

The trade-off for the outdoor grower is receiving more in less frequent harvests. If you only have a few marijuana plants, it is some- times possible to cover them completely and induce harvesting, but this is not a functional reality for most cannabis growers.

The light and darkness factor works 170th ways though. Some growers will actually shine very bright lights, like halogens, on their marijuana plants during the night in order to reset the internal clock. This is useful if you wish your plant to grow in size and not begin its flowering.

In Australia some Sativa varieties can grow to 16 feet with internodes around 3 to 4 inches in variety. Obviously a plant of that size will produce a large amount of recoverable crop, but getting it that size requires a year-round growing season.

To get it that size they may need to convince the marijuana plant that it is not quite time to flower, and that perhaps it should continue using its energy toward leaf production and upward reaching.

Another good way of identifying a general time for harvesting your plants is thinking about the September Equinox. This is not a clear rule, however, so don’t blindly harvest on this day.

It is a good point in the calendar for knowing when to stop watering. You should cease your regular watering schedule a few weeks before the September Equinox.

As the date gets closer, be extra careful to notice any differences in your cannabis plants that might mean they are ready for the harvest. Your plants should stop growing taller and should begin flowering instead. Focus on how fast your plants are flowering and the other physical aspects of the plant.

The most important part of choosing the correct harvest time is the flowering period. You can expect six to twelve buds per plant once their flowering phase has begun after the light has decreased. The rate will begin slowly, but then will increase rapidly (like when you make popcorn).

More buds will appear, and the already existing buds will also continue to grow. When you can see that the rate of bud production is decreasing by a large amount (like when the popping rate decreases in popcorn), the flowering phase is complete.

flowering phase is complete

Flowering phase is complete

Mark your calendar for one week after the last day of the flowering period. This is when the plants have grown as much as they are going to, making it the peak time to harvest your plants. Once again the popcorn metaphor can be useful - if you leave the popper or microwave on for too long, the kernels will start to burn.

Even if there are kernels that remain unpopped, it is the right time to turn off the microwave. The same goes for marijuana plants. Although you might be missing out on a couple new buds, letting it go on too long will be a worse consequence when considering the entire yield. You never want to jeopardize the first few buds in order to get a couple more.

Harvest security

The most crucial element of harvesting your plants is your security. Don’t let your excitement to harvest the marijuana make you forget about your personal security.

This is perhaps the important time for ensuring your safety since you can’t exactly deny the fact that you own the plants if you are caught in the act of removing them. Therefore, you need to be extra cautious in the days before and on the day itself. Don’t inform a single person that you are about to harvest, and on the actual harvesting day you should be extra careful about telling people where you are.

Harvest security cannabis

Security is importent while you harvest

Until the harvest, security is mainly a matter of diverting unwanted attention away from your marijuana plants. All of this changes as the flowering period ebbs, because now you must concern yourself with your actual yield. In this situation, cannabis growers have been known to resort to some very elaborate and even over-the- top means to protect their buds from prying eyes.

While some will sleep near their ''babies'' for the days immediately leading up to the harvest, others will set up trip wire that rings a bell if anyone approaches. If their site is close to home, they might keep a dog that barks a lot outside all night.

Other cannabis growers simply watch the known entrance routes like a hawk. During these days the growers are irritable, cranky, and extra paranoid, but with a year's supply (or oftentimes, even more) of cannabis at stake, can you really blame them.

It is also important to remember that all of the other security concerns still apply and the same level of care (if not more) should be taken. It is not unusual for marijuana plants to be staked out by potential thieves who are waiting for them to grow big buds so they can reap the benefits of your time and effort.

Police taking cannabis from grow site

Police taking cannabis from grow site

The police could also have detected your plot weeks ago and be waiting for you to walk into a trap that you yourself have unwittingly set. When you show up at your site with shears, bags, and a backpack, it is hard to claim ignorance.

Therefore it is important to do the following things: pick as secure a grow site as possible, and if you suspect that something is wrong, relax and walk away. After all, it's just marijuana, it is not worth going to jail, or getting into a fight about.

How to harvest outdoor marijuana

Bring sealable bags. And if you bring like ziploc bags, make sure to bring a holdall because ziplocks are transparent (these bags are not transparant and odor free).

Cut your plants into lengths that are easily transported - cut the stalks so they fit into your bags. Make sure you are not spending too much time at your site when harvesting; be efficient and fast. Just remember: all that matters is the removal and safe transport of your plants; however you do that is up to you.

Make sure your harvest outdoor is done a safe amount of time before the first frost has a chance to damage your plants. It is best to harvest on a beautiful fall day with clear skies and lots of sun. Don’t overthink this, however, as harvesting in the rain won’t be the end of the world.

It will increase the drying time only by a fraction, and it will have no effect on the buds and resin glands. Don’t relax until you’re home safely with all of your plants. Once you have accomplished this, you will have very little to worry about from now on.

There isn’t a black and white way of being able to know what your yield will be like ahead of time. You can identify a few signs that will give you a basic idea of whether the yield will be really good, decent or poor. All of the factors that you have already worried about (sunlight, water, and soil) will have an impact on the final result of your yield.

You can expect a few specific quantities. For instance, if the plant is five feet tall, you should get a minimum of between two and six ounces of bud. Taller and bushier plants will produce more, of course. If any changes took places after the peak harvest time, you can expect a significantly worse yield.

Harvest twice per year

Some skilled marijuana growers are able to accomplish a double yield during a single season. One method is buying autoflowering marijuana seeds because it takes only 10 weeks for them to grow from seed to harvest.

outdoor autoflower cannabis plants

Outdoor autoflowers cannabis

There are some specific methods that can be used to be able to get this second harvest. A successful second harvest depends not only on how well you perform these techniques, but also where you live.

If you are in a climate that is further north, your cannabis plants are most likely already vulnerable to an early frost or other seasonal changes. In that case, accomplishing a second harvest will not be as easy.

If you live in a more temperate zone where early fall is fairly mild, you might be able to successfully harvest your cannabis plants more than once during the growing season. It all depends on your technique of harvest in this case.

You can’t harvest plants normally once and then later decide you want to try a second harvest - the process begins already during the first time you harvest. Once you have removed most of the harvest (allowing only the tiny buds and most of the leaf to remain), you are ready for the next step.

Immediately start up the same process that led to the first growth cycle that your plants have already been through. Add lots of water and some fresh fertilizer to stimulate another round of growth.

Make sure to buy autoflowering marijuana seeds in our online seed shop

You basically are just trying to get the cannabis plants back into their flowering phase so they produce more buds that you can harvest. If you leave most of the leaves, you will have a higher chance of the second flowering phase to be activated since they are what absorbs the sunlight that the plants need for growing energy.

Because the timing and intensity of the sunlight have already changed, the plants are already in their flowering phase. If you are living in a location that continues to have mild temperatures through the beginning of fall (such as in tropical climates), then you should be able to continue your plants’ vegetative phase even longer.

You do this through light manipulation - simply have a light of some sort shining on the entire plant in the nighttime. This can be done with a flashlight.

light manipulation cannabis

Light manipulation with LED

If you have successfully interrupted their period of darkness normally required for the flowering stage, you will have started the plants’ growing back up again. When you want the plants to begin their second flowering phase, simply stop interrupting the darkness with your light.

Keep in mind that flowering takes a couple weeks, so don’t keep the plants in their vegetative phase for too long. For instance, if the first frost or colder weather will be there within two weeks, then you should have already started up the flowering process three weeks prior.

easy peasy and I am surprised it wasn't stated on this. I take a jewelry loop and look at my flowers. You can see tiny trichromes which are mushroom shapes that form once in flower if they are clear then not ready. Trichomes look like mushrooms when they have white smoke in them some like to take then says more uplifting . When they turn to a amber color people say more of a couch lock. Don't let go past when they turn black.

Yeah, you can "RE-Grow" the SAME Plant(s), and Even BETTER, the Bigger the "SKELETON" stays, the Better, Bigger and Faster it will be! (U CAN DO IT MORE TIMES!!! but it will become WEAKER!!!)
I allready did it 4 times with One, and only at the 4th time it "SEEMED" to be weaker!!!
You will have to leave as many, Leaves and "Popcorn Buds" (small/medium/big) do it so it Remains as MUCH "Green STUFF" able to Grow, as possible! Because, the More "Remains" or Leaves and "Popcorn Buds" stay in the Plant, the QUICKER the "ReHab" will be!
Give it Nutrients and Lots of LIGHT, as if it was a New Plant, with More Nitrogen and other "Nuts" or Boosters, but Slowly as you would do with a small Plant! 😉
Hope this helped KSpence

By James on 5 September 2015

Thanks for all the info really useful

By latewood on 7 September 2015

It is totally possible to re-vegitate a plant if you leave enough foliage for the plant to heal it self. However; A re-Veg would begin immediately. This would be totally based on climate. If you are in a moderate climate it is possible. If you are in a harsh winter climate, then no. Once the plant dies, and there is not healthy foliage; You must start over.

By Jennifer on 9 September 2015

my plant is outside and it gets plenty of direct sunshine, with the summer coming to a end should I bring it inside? Its just beginning to flower, or can I leave it outside doing the upcoming months?

By latewood on 12 September 2015


That all depends. The plant will finish as the season ends. i.e. As days day shorter and cooler the plant will adapt and finish.

Without knowing the region; Or, "Zone" you live in; It is hard to give you completely accurate advice.

By Welton on 12 September 2015

OK live in Michigan and going through first ever outside grow. Plants at 8 and 10ft tall. They have buds covering then but not huge buds. My pistols are still light green. Weather getting cooler with highs in 70s. I'm wondering how much longer I have be for I should cut them down. I was told th hey could survive into October. Advice please.

By Claude on 10 September 2015

Here is the way I proceed to harvest. First, I cut off all the tops of my plants (30 of them) so I harvest only the big buds. I do that for all my plants. Then I take off the foliage oh what is harvested and make a rough trim. I suspend the branches head down and with ventilators I let them dry. Ater that, I cut the buds off the branches and make a final trim of all buds. Then I start over until all of my plants are completely harvested. Sure I harvest for over a month but the results are very very good. When the tops are off the plants, the sun penetrates more into the branches and the buds get as big as the top I previously harvested.

By Jennifer ILGM on 11 September 2015

Thanks for sharing claude!

By Deb Bandy on 11 September 2015

Hi, Claude! Thanks so much for your detailed narrative on growing/harvesting outdoors! You made things so much more understandable for me. My 1st "inground" garden this year...

By Houston B. on 10 September 2015

While I look to your site for growing and harvesting tips, I agree with Jools above that this article is just a bit useless to the average home grower. Believe it or not, most of us are not growing 30 to 40 plants in a national forest close by. I grow half a dozen plants in pots on my deck, and I'd bet more of your readers fit my profile than the other. Also, 75% of California is frost-free, so that has no bearing on harvest decisions. anyway, keep up your good work and remember your audience. Peace.

By Andrew on 14 July 2017

I have a question... In another article, I've read that THC content is highest in the middle of the night, since the plant isn't busy photosynthesizing... Wouldn't that mean that one might want to harvest on a beautiful fall night? Just a thought. Thanks!

By Bud man on 22 September 2017

I thought that resin moved up and down like sap in a tree. So that the time to harvest is early pm whothe sap is up in the plant. Coments appreciated.

By latewood_ILGM on 27 September 2017

Bud man,

Nope, We want to harvest just before or asap after daylight. As the Sun influences the plant, it takes up more nutrients. We want to harvest before this occurs for the best taste. Also; YHC decays in light, so most people believe that harvesting in the dark is beneficial to the final THC potency.

By Debbi on 10 September 2015

I live in northern with never grown here before so I'm not sure when to harvest my plants.
Please help

By ziplock on 11 September 2015

Read the article again, and take notes. Your plant and your weather will dictate when to harvest. Mother Nature doesn't give guarantees. It's entirely possible that someone can have their weather deteriorate into cold and rainy, in which you can lose your crop because it will not ripen in those conditions. So use your head, keep your first crops small, and allow for unexpected surprises.

By latewood on 12 September 2015

By David Manevich on 11 September 2015

I've been growing indoor in hydroponics but I put 3 in my vegetable garden this year actually started as a joke but 1 lived and is doing great. I'm in north east Ohio USA and I planted first week of June. I've been watering with my used nutes from hydro grow through the season each week when I do my water change and sprinkler as needed throughout season. .I tied all branches down low for security but also for more light similar to a scog setup... I'm figuring around mid Oct for harvest does this sound about right timing wise. Oh yea and thank you for continuous information its been very helpful even to my hydro grows you give us the best info out there that I can find.

By latewood on 12 September 2015

It is really hard to say, exactly. You did not mention a strain. (whether genetics are Sativa or Indica dominant.) From the time frame you mentioned; (early June), This could be just right. Unfortunately; Plants do not finish in exact time frames.

If you are concerned that your plants are not finished, and it is dangerous to keep them outside; Join our "Support Forum" . We have members from all different climates, willing to help out.

Get some sort of magnifier and watch the tricombs. They will first look like they are filled with clear liquid. They eventually will look like they are filled with milk. When the thc inside these tricombs begins to degrade the liquid will turn an amber color. I have found the best time to harvest is when around ten to twenty percent of the tricombs turn amber.

By William on 23 September 2017

A great way to examine trichomes, and pistils with magnification is to take a photo(s) with your phone, then enlarge with fingertips smear (? you know); anyway, you get a nice magnified close up of your beauties

By Joe on 13 September 2015

First few amber tricombs are visible the rest milky. Weather forecast has 1 1/2 inches of rain 2 days away. What do you think harvest now ( a little early ), or wait til after the rains and are there any negative effects of a steady 3 day rain this late in flowering stage?

By iknowtrichome on 13 September 2015

You need to start boosting the P-K right now! If your plants aren't getting swoll and you don't give it what it needs you will be missing out on her full potential... Also you should defoliate your plants first sign of budding. It forces nutrient uptake to the swoll buds and allows more sunlight to directly influence bud growth.... Grow on..... Feel free to ask me any tree

By Juanita on 7 June 2018

I have read on quite a few occasions that you should exfoliate the plant at the first sign of flowering. I am in week 5 of flowering 2 beautiful BlackBerry Kush girls in a tent under 2 50w full spectrum LED lights, and just before I turned light cycle to flowering, I read somewhere about the plant still needing to photosynthesise and the importance of it. So I found myself conflicted about exfoliating. I decided I have two plants, so do one to each. So I defoliated one of most of the big fan leaves and the other I left mostly the same except for removing a few fan leaves blocking light from reaching the bottom buds. The defoliated plant's remaining leaves are still very green and healthy, but I've noticed they have a shine to them. The undefoliated plant, kept the dull green. They have been fed the exact same amount of nutrients at the same intervals. They were both put into flowering on the same day. And so far, 5 weeks in, I have come to find that the unaffiliated plant's buds are almost twice the size of the other one. But I guess, proof is in the taste, so we will see.

By latewood on 15 September 2015


You can go wither way. I would not see any problem with rain; As it rains on outdoor plants all the time. I did not see you mention cold being a factor. This comes down to a matter of choice, by you. 🙂

By linda on 13 September 2015

I agree, a lot of words with little info.

By Debbi on 14 September 2015

I have been told that when I harvest my plants they say to put the roots in hot water before I hang it.Why is this?

By latewood on 15 September 2015


I have never heard of that in all my years. I shop the bottom of plant off.

By Debbi on 15 September 2015

Thank you I haven't heard hat before but I was woundering.thanks again

By Michael Obschonka on 11 April 2017

Hi Debbi,it's was popular in the mid 80ies and was to force sugars and potential resin to to tops of plants.sugar was placed in the boiling pot and did change the colour of the plant after drying.

By Bryan on 14 September 2015

Would it be advisable to bring a 15 gallon, 3 foot plant indoors and run MH lamps on a 20/4 schedule and restart them as indoor plants? From what I read above on running a second cycle, it would seem possible to bring a few of these veterans indoors and get a new start. Are there drawbacks, other considerations?


By latewood on 15 September 2015


15 gallon 3 foot plants. Not sure what you are getting at. Somewhat vague overall on your description.

Yes; You can bring plants indoors; B Ut, Why would you?

Yes you can revegitate plants; If that is what you are asking

By Uncle Scotty on 17 July 2017

Yes, definitely bring them inside. Leave lots of greenery on them, put them under the lights, re-fertilize (not crazy amounts) and they will be fine for the Winter. Put them out again in the Spring and wait for crop number two!

By :b on 17 September 2015

Growing in central Washington my plant has been flowering for a bit over 3½ weeks any estimates on when i should start to flush and harvest its my time growing outdoor its a blue dreams plant and any suggestions on gettibg nugs frostier

By latewood on 21 September 2015

b on

You have a minimum of 4 weeks left if growing predominantly "Indica" plant. as much as 8-10 weeks if growing predominantly, "Sativa". You are flowering fairly late in the season.

My question is, if the buds are starting to get Brown in them, is it harvest time, they look like they are ready, but, this is my first time, they are growing outside? Thanks..

By latewood on 21 September 2015


I suggest you join our support forum and find our "ILGM support ticket". I created this for growers in need of direction when starting out; or , when in trouble, having issues during a grow. You can find, copy, and paste this Support ticket, located in the beginner section of the ILGM Support Forum. Thanks. 🙂

By latewood on 21 September 2015

And I can say; Maybe you are ready to harvest, if the buds are getting brown.. really need a picture. As a warning; Turning brown usually means dryied out. Hope this is not the case. Join the forum. Peace 🙂

By ron on 29 August 2016

Wat if the buds get mold on them

By WW on 13 October 2016

Cut them off and throw away to save buds not molded. You wouldn't want to use them for any thing as you will be ingesting mold which is not good for man or beast.

By Amy on 23 September 2015

I have multiple strains outside. Growing in Washington (about an hour from the coast) Weather is 67-75 degrees high to 42-50 degrees for the low. My outside grow is really green still and leafy, the buds are about 5 weeks into flower. Should I pre trim everything in prep for harvest? Tri combs are varied, clear to cloudy, (depending on strain) I am worried about the weather, it is forecasting rain. I have had no bud rot issue yet, but have had to treat with neem oil to fight off powdery mildew. I am just confused as to when to chop them down. I don't want the rain/weather to cause me to loose the bud...

By latewood on 24 September 2015


Without knowing whether you have Indica Dominant, or Sativa dominant plants; It is hard to judge a finish time for your buds. Some small Indica can finish in 6-8 weeks. Clear cloudy is early. You do not want the plants subjected to temps of less than 40 f for any prolonged period of time, as this causes cell decay and, death.

Feel free to join our Support Forum for varied opinions and expert advice. We have many growers in the community that are out your way. 🙂

By Debbi on 23 September 2015

I was wondering is 39 degrees getting to cold for my plants?

By latewood on 24 September 2015

Plants are OK down to 50 f. Between 40-50 f; Plant cells start to deteriorate. Below 40 f; Plant cells start to die.

By Bodie on 10 October 2015

During transition, does the first week of transition count towards the 63 days of flowering?

By latewoodl on 15 October 2015

Do not get caught up with counting days. That # is is a suggested time frame. Growing methods, and local environment can cause the # of days until finish, fluctuate. You do not harvest until the buds are ripe; Meaning, that you read the "trichomes for maturity", before you harvest.

We have an excellent grow support forum. Have you read our Free Grow Bible?

By Ruby on 3 November 2015

Dudes, could you address the "flush" with respect to timing, PH and PPM prior to outdoor harvest. My girls are at that stage and I've never flushed before. The Indicas are ready. The Sativa has a little longer but it is getting cold. (These are probably misspelled - missed that class.) Also, I've been told that leaving the bud on a little longer will convert to higher CBD. Any thoughts? Thanks

By Ruby on 4 November 2015

Would someone be kind enough to reply something???

By latewood.ILGM on 5 November 2015

Dude...If you joined our support forum you would get support in a more timely manner.

When you flush; You just water the plants. Same PH you would use to grow with. Perhaps you should download and read our Free Grow Bible.

When i harvested last time, i put the fresh buds in a plastic bag and moved it safely to the drying house. when i opened tha bags the buds were all weird smelling and their color turned darker dramaticly. I think this was because of the still wet air in the plastic bags. The plant remaind potent after drying but the taste and color were all gone. Any one had a similar experience ?

By latewood.ILGM on 4 March 2016

I am happy to say that I have not had that problem. It is a bad idea to put wet weed into plastic bags though. You found that out..Better in Paper Brown bags IMO. I do realize the smell may be stronger. On the other hand; I never transport a fresh harvest anywhere; It is more advisable to dry it where you grew it. I also realize that you may have grown outside, and I guess you didn't have a choice.

You would find more ideas on our grow support forum! 🙂

By Sid on 29 April 2016

What about auto flowering for earlier harvest and standard for backup?

By latewood.ILGM on 30 April 2016

Sid, Sid, Sid...

That is what we all do. Autos, Feminized 6 weeks later. Harvest the Autos. Induce 12/12 for the Fem's. :ds

Ir is all good !

By latewood.ILGM on 30 April 2016

Sorry. I meant; After 6 weeks of Autoflowering; Add Feminized seeds. Another 6 weeks and you finish the Auto flowers. You can then switch to 12/12

By Rino on 11 July 2016

I'm potentially growing in Colombia, on the equator where there are no seasons and usually plenty of light on my roof deck. How many crops could I potentially get then? How quick is the turn around from a plant I obtain that's a foot or two tall to start?

Can l grow 5_10 different varieties without cross fertilization. Do you sell 5 to 10 combinations.

By latewood.ILGM on 5 December 2016

Cross pollination only happens in breeding seeds. You may have some traits transferred if you grow many different strains at one. (not advisable)

Growing 5-10 different strains is labor intensive due to the fact that Sativa dominant will grow taller and longer to finish than Indica dominant strains

No you do not need to uproot plant to harvest. Some growers cut off plant above pot and hang entire plant, and other growers remove fan leaves from and cut off individual stems.

By latewood.ILGM on 17 July 2017


I welcome you to join our forum at In order to truly answer you, we need to know how many plants in what size pots, and on and on, etc...

Yes you can move the plants inside. You will need strong lamps in order to get anywhere close to mimicjking the Sun.

By Joseph49 on 4 September 2017

For kicks I read through this comment section and it's really bizarre how a bunch of people are commenting who obviously didn't even bother reading the article. The article is about WHEN to harvest and people come on and they say.... When should I harvest? They're like "Hi I live in northern. One of my plants died. The other one is six feet tall, should I harvest now or wait till the buds are ready to be harvested?" Seriously. There was one person who literally said "Help what's wrong with my plants." Did that person think somebody with psychic powers was going to magically know all about their plants and report back to them?

By Amy on 14 September 2017

I have yet to start, however, by me reading all the info and forums I already have a clear idea from start to finish. Unfortunately, I have found little info on growing in water indoors. Which is best in soil which is claimed to be most popular or in water which reads it's harder to keep nutritious but to me seems like it would be much easier to read pH balances and nutrient balance. Any thoughts or comments to help with my decision?
Another question, can you grow in water inside the "tent" method which I am choosing for my grow area? Also, I'm really unsure as to what is actually needed for basic supplies to set up from scratch as far as co2, ventilation methods, and so forth. The list of basics supplies are unclear to me and readas though they r in a different language. When I search for the products, the dealer website shows me all different products. "Inlet" what the heck is that? "Extractor" for what is that used for? The website is unclear. "Filter" for what smell, co2?? The star up is where I'm lost PLEZ HELP so I can get started on ordering my supplies and get going

By Paul on 22 September 2017

Why do my plants only grow straight up and not bush out like all the pics I've seen?

By E on 22 September 2017

Are you topping, pruning and super cropping during veg stage? You also have to train your plants with a "screen" (string netting) to grow sideways during flower stage. If you do these things, your girls will bush out.

By latewood_ILGM on 28 September 2017

Yes we do.

Thanks for sharing 🙂

By Mitchell on 22 September 2017

I grew two plants this summer (first-time grower), in a plastic hoop-house. Both developed bud rot at what I'm guessing was about one week before the plants were ready to harvest. Can I still use the plants, or are they write-offs? The bud rot only affected two or three buds per plant.

By Donna Laliberte on 23 September 2017

I had the same problem today. I just cut out the rot and left the rest to dry.

By latewood_ILGM on 28 September 2017


carefully inspect and get rid of the rotten area. You should be able to use the rest of the plant that is unaffected. Good Luck

By Minnehonk on 22 September 2017

From my 45 years of experience of outdoor growth in Maine, (where it is now legal to grow 6 plants per person) for a successful grow, I use organic fertilizers conservatively, small amounts of chicken mixed with aged cow manure added to the soil at the beginning of the season, than Fox Farm Big bloom at the beginning of budding when watering weekly, then begin my flushing when the glands turn milky, with 1 tsp of molasses diluted to each gallon of water, one more last flush of just water a week later. no more watering until harvest when half of the half of the pistols are brown.... average yield per plant 6-
12' tall depending on strain is 4- 6 ozs. of skunk smelling , grape tasting, awesome weed !

By latewood_ILGM on 28 September 2017


Thanks for sharing. Molasses does not break down fast enough to be used in such a manner. To each his own. Just sayin' "Science".

Happy growing

By Sherry on 22 September 2017

I'm a bit confused about the drying process specified in the Grow Bible and that specified here. The GB says dry at 90 degrees and then let cure 5 weeks. This says 64 degrees with 45 degree humidity and a fan.

By latewood_ILGM on 28 September 2017


I could not find this stat in the article above.

When harvesting; Hang plants until the stems "SNAP" like dried twigs.

Place in a paper bag to allow the inner bud to dry out and balance the moisture throughout the bud. Room should be 70-80f Humidity should be from 45-60% for curing. I also make sure an oscillating fan is recirculating air and not blowing directly on the buds.

Once buds appear completely dry, place into glass jarsd with a packet of 58% Boveda which will keep the RH at 58% making a perfect smoke. In dryer climate, a 62% Boveda packet might suit you better.

My bud has red hairs , but the tricomes are clear . Should we be harvesting?

By latewood_ILGM on 26 September 2017


No do not harvest with clear trichomes indicating no THC is producing yet Wait for heavy cloudy trichomes with some amber colors before considering harvest.

Happy harvesting 🙂

By Cozmo on 4 October 2017

To Whom It May Concern ......i have Bergmans gold leaf strain straight from seed,, How long is the flower stage of this plant., this plant had started outside then brought indoors around last week of sept., due to weather ,The Flower started in beginning of august ...???

There is no set time for finish. Finish time is influenced by grow methods, veg time, etc...You harvest when the Trichomes are mostly cloudy wiht some amber. How much amber is your choice. Less amber = more up high, more amber = more medicinal effect.

Harvesting Sativa too early can cause a short anxiety after smoking. 🙂

After breaking down plant for transportation and into plastic bags ..what’s i take them out and hang or just leave the bag open a bit to dry out...also i tried to dry like “ Tobacco “ i read somewhere.. now leaves are kinda crunchie, can i rehydrate..???

By latewood_ILGM on 9 October 2017

Deborah Nash,

You should hang the plant and you wnt leaves to get crunchy. Buds qwill remain damp inside and must be curder. rather than explain the whole drying curing process; I suggest you join our support forum

I have been growing outdoors as well as indoors for a few years now. To date have not found any unusual problems that you guys didn't have a solution for! The Bible has great illustrations and soooo much information!! Thanks for all you do!!! Mountainman2

This is the first time I have tried to become a grower. My plants are growing fast and seem to be strong. I am going to try and do the scrogging to keep the plants low and bountiful. Really don't see to much info on scrogging outdoors, going to try and follow the indoor instructions.

Why would you put weed in the microwave,or stove. That is disrespectful the plant, and also it makes me question your ability to grow. When you wait a half a year for a good grow don't waste your time. Just wait for the product to be 100%.

By latewood_ILGM on 21 August 2018


Sorry to offend you but, we share all options with the public and allow them to make a choice as to what suits them. IN general we do not condone microwaving plant matter but, sometimes a grower needs medicine immediately and this type information allows them some relief from the anxiety as to whether they can take a shortcut.
Another way to look at it; We share the good techniques with the bad, and hope growers will learn the correct way as we teach them. Otherwise; We would be asked about the questionable methods anyway.

Thanks for the critique on our article. Happy growing 🙂

Hey Y'all. First timer here. Any use for trimmings/leaves etc when harvesting (on a VERY small scale!) Waste not, want no

By latewood_ILGM on 12 September 2018


On a small scale, not much to use trim for. If you want, you could make an infused Coconut oil, but, You need to be able to fill a mason jar with trim. Making Infused Coconut oil is an 8 day process using a sous vide. Check out our forum; I think one of our Moderators did a topic about making this oil. We also do have some secrets to even further the intensity of Infused coconut oil which FYI is: Edible, can be used to cook with, and it also topical, providing pain relief. God stuff 🙂

What a great site. Thank you so much!

I noticed a typo: This is no accurate way of deceiding when it's time to harvest but it gives a an idea.

I looked it up and it is spelled "deciding".

By Stacy ILGM on 18 September 2018

Thanks for pointing that out Fred, we fixed it right away! 🙂

By Rick Montoya on 19 September 2018

I noticed that you said harvesting them on a beautiful fall day I have heard that is a major No-No do not Harvest during the day you need to harvest in the middle of the night early morning before the sun comes up that way you get maximum THC CBD and nothing else in the plant so always Harvest about 3 a.m. great article loved it

I've been trying for a few years now to download your Grow Bible. I've yet to receive it.

By latewood_ILGM on 25 September 2018


You do not download the Grow Bible until you enter your email address and receive an email with the link which allows you to access the server where it is located. good Luck 🙂

By Chet on 19 September 2018

Im in So Cal and in this article it mentioned year round growing outside. Can you determine year round growing potential by locating your 'Western Garden Climate Zone' ? Are there any other factors to consider, especially with the auto flower?

By latewood_ILGM on 25 September 2018


The only thing to consider when attempting to grow year round outdoors is whether or not your climate will remain in the necessary temperature range that would allow you to continue to grow through out the winter. In So Cal; I believe you can grow year round...period

Hi ,
Great site by the way . I live in NE Scotland my auto flowers which were planted 22nd june still haven't flowerd the buds are now coming they are in a polly tunnel but it is now getting pretty cold and not that many really sunny days , i realise the flowering process is very much light based but is there also a certain amount of heat also required ? Im hopping I just have to be patient. Any advice would be great.

By latewood_ILGM on 4 October 2018

robert burns,

It is required that you keep the plants at least at 60f. That is a bit cold but, plants adapt. I suggest you join our forum and see what other members in your area have to say. I would also suggest trying to enclose a space that can be heated. Happy growing, 🙂

Thanks for taking the time to share the abundant amount of information it takes to help us grow! I find this site the most helpful and easy to read/follow. I am totally surprised at most questions asked here though, did everyone not just read the same thing I did? All of that was covered in the above article! So thanks again for having patience to continue to answer those same questions over & over again!! Btw..I too am about to harvest my first grow. A lil' conflicted on a couple issues but that's why I turn to your site.

By Stacy ILGM on 9 October 2018

Thank you for the kind words! And amen on that, but it's our job. We love to spread the info! 🙂

By Linda on 12 October 2018
