Outdoor Marijuana Grow Calendar

Grow calendar USA North | Grow calendar USA South

Grow Calendar – Northern Edition:

Tired of snowstorms and ready to grow some weed? The outdoor growing season may not officially begin until mid-May, but there’s plenty to do before that time comes. In fact, taking the time to prepare now, will make this summer’s grow harvest even more bountiful.

If you live in the northern half of the United States, believe it or not, your grow season is right around the corner. The upcoming longer days and warmer temperature are exactly what your plants will need to grow great buds.

Curious about what to expect each month? This Outdoor Grow Calendar covers it all. We’ll show you average day lengths and temperatures for the northern half of the country, including Alaska.

A Few Notes:

  • Averages are based on Seattle, Chicago, and New York
  • If you are growing on the northern West Coast, your springtime temperatures will be the warmer average, and your summer averages will be cooler than average
  • The most amount of sun is found in Alaska, with the Northwest coming in second

February

Average Day Length: 9 hours 30 minutes to 11 hours 15 minutes
Average Temperature: 22 degrees to 51 degrees

Alaska:
Average day length: 8 hours 30 minutes to 10 hours 30 minutes
Average Temperature: -8 degrees to 12 degrees

It’s cold outside. Now is the time to pick out your seeds and complete your orders. Many Northern growers choose Indica dominant plants because of the short growing season.

In places like New York and Boston, it may seem like the frosty, cold temperatures will never end. However, if you start your plants indoors, you can extend your growing period so that you can grow any strain. You can sprout your seeds indoors in an controlled environment with artificial light at the end of February

buy your seeds

Also germinate your seeds if you want to make your own clones.  Grow your mother plants inside until its warm enough.

Create a cozy indoor growing space with a CFL grow, 18 hours of sunlight and of course, some fresh air. Your grow area should be kept between 68 and 77 degrees. Check out “how to germinate marijuana seeds” for specific guidance.

You can also begin prepping your soil if you aren’t in Alaska or the Midwest. After the last frost, loosen up your soil by adding worms and compost.

March

Average Day Length: 9 hours 30 minutes to 12 hours 50 minutes
Average Temperature: 31 degrees to 54 degrees

Alaska:
Average day length: 10 hours 40 minutes to 13 hours 15 minutes
Average Temperature: 0 degrees to 24 degrees

It’s starting to warm up on the coasts, and the days are getting very long around Seattle and Portland. Growing time is getting close. If you haven’t already ordered your seeds, do it now.

You should also have your mother plant ready by the end of this month if you plan to use one.

If you are ready to go, you can start sprouting your plants in a windowsill at the end of the month. Make sure they get some good sunlight and keep a good watch on the day length. By this time, areas near Seattle are receiving more than 12 hours of sunlight, while Alaska has 13.

Start sprouting your plants

However, most of the country will not have as much sunlight. If your plants aren’t getting enough sunlight, set a lamp over your plant a few extra hours each day. That way, you won’t have to worry about premature flowering.

April

Average Day Length: 12 hours 40 minutes to 14 hours 25 minutes
Average Temperature: 35 degrees to 62 degrees

Alaska:
Average day length: 13 hours 15 minutes to 15 hours 45 minutes
Average Temperature: 24 degrees to 45 degrees

Congratulations, it’s April! That means flowers, followed by May showers. The middle of this month marks the beginning of long days, with everyone having at least 14 hour days by the end of the month. Once the days are that long, you will not need any more artificial lighting.

Your windowsill plants will not need any more help with light once the days reach 14 hours, and your seeds will find it easy to sprout.

By the end of the month, it’s safe to take your plants outside – especially if you are on the West coast. Simply put them in a container and put them outside, bringing them indoors at night. Midwest growers may want to make sure the risk of frost has passed first. Alaskan growers will need to wait another month or place the plants in containers and bring them inside during cold nights.

May

Average Day Length: 14 hours to 15 hours 40 minutes
Average Temperature: 52 degrees to 72 degrees

Alaska:
Average day length: 15 hours 45 minutes to 17 hours 45 minutes
Average Temperature: 40 degrees to 61 degrees

It’s finally Spring – even in Alaska. If you live on the Alaskan coast, it’s probably okay to start placing your plants outside. Stay vigilant for frost, of course. The Alaskan interior should wait until the middle of the month – just to be safe.

If you have autoflowering seeds, you’ll begin sprouting them the second half of this month. They need three months of summer to grow, and for some parts of the Midwest and Alaska, that’s all the time you will have before the freezing temperatures return. Expect your harvest to be ready mid-August.

June

Average Day Length: 14 hours 50 minutes to 15 hours 55 minutes
Average Temperature: 54 degrees to 81 degrees

Alaska:
Average day length: 17 hours 50 minutes to 18 hours 15 minutes
Average Temperature: 52 degrees to 71 degrees

June is when your plants will experience the most growth – especially between June 18th and June 24th. You’ll see your autoflowering plants grow rapidly as they begin to develop flowers. Your non-autoflowering plant will also speed up, thanks to the warming temperatures.

Cannabis plants getting flowers

Autoflowers are getting flowers at this time

July

Average Day Length: 14 hours 5 minutes to 15 hours 55 minutes
Average Temperature: 58 degrees to 85 degrees

Alaska:
Average day length: 16 hours 30 minutes to 18 hours 15 minutes
Average Temperature: 55 degrees to 73 degrees

In this hot month, your autoflowing plants will now have large flower cluster, while some non-autoflowering plants will have their first pistils.

If you decided to use regular (non-feminized) seeds, now is when you’ll need to be checking for male plants. Keep an eye on the side branches and quickly remove them. You’ll recognize the males because they will develop flowerheads at the root of the side branch. These flowerheads will look like two small balls that are resting on a short, thin stem.

Male vs female cannabis buds

Female plants, however, will have drop-shaped calyxes that have two white pistils protruding from them.

August

Average Day Length: 13 hours 5 minutes to 14 hours 55 minutes
Average Temperature: 58 degrees to 84 degrees

Alaska:
Average day length: 14 hours to 16 hours 25 minutes
Average Temperature: 49 degrees to 66 degrees

Remember those autoflowers that sprouted back in late May? It’s now time to harvest them. Cut the flower heads and hang them upside down in a dark place to dry. Dry them at room temperature - don’t try to speed up the process by making it too hot. It should take about 10 days.

dry autoflowers

Dry your autoflowers at this time

You’re done when the branchlet cracks when you bend it.

Near the end of the month, most areas will have less than 14 hours of sunlight. Alaska is the exception. Once this happens, non-autoflowering plants will begin their last flowering phase.

September

Average Day Length: 11 hours 40 minutes to 13 hours 20 minutes
Average Temperature: 54 degrees to 76 degrees

Alaska:
Average day length: 11 hours 30 minutes to 14 hours
Average Temperature: 38 degrees to 55 degrees

If you are growing non-autoflowering plants, (photoperiod plants) they will start developing more pistils and flowerheads at the beginning of this month. You’ll want to make sure they stay dry during this time – perhaps, build them a shelter, or take them indoors.

Marijuana plants inside to dry

Take your plants inside during cold and rainy days if you have the space

The Wind can also be a problem during this month as the seasons start to change. Prevent your plants from falling over by adding a net or using bamboo sticks.

Fall officially begins the end of this month, but it will be a slow transition on the West Coast and in Alaska as the sun tends to linger around a bit longer.

October

Average Day Length: 10 hours to 13 hours 5 minutes
Average Temperature: 46 degrees to 64 degrees

Alaska:
Average day length 11 hours 30 minutes to 14 hours
Average Temperature: 20 degrees to 33 degrees

Autumn is officially here, and many outdoor-grown plants have bloomed. Unfortunately, this is a high-risk time for most northern growers. Especially in areas where it’s cold (Midwest and Alaska) or wet (Pacific Coast), you need to keep an eye out for bud rot.

If you notice any signs of bud rot, it’s time to harvest. An early harvest is better than none at all. Read more about bud rot the the article "How to prevent Bud Rot"

The United States has multiple climate regions, each affecting how your plant grows. In general, marijuana loves mild temperatures and plenty of sunlight, which can be found in many parts of the country.

Do you grow in the northern half of the United States? Did we miss some important dates?

Let us know in the comments below, and we’ll update the calendar. We love reading your comments and your experiences and believe that together, we can all grow the best weed.

Here’s to a great harvest!

Grow Calendar – Southern Edition

Grow Calendar – Southern Edition:

The days are growing longer, which means it is almost time to grow some marijuana! Sure, the true outdoor growing season doesn’t start until mid-May, but who says you can’t get started early? In fact, there is a popular saying: “the early bird gets more bud,” or at least that’s how I remember it.

Don’t let the long winter fool you, for the southern half of the United States it is almost time to start growing! Keep an eye out for that last front and use this calendar to help plan this year’s grow season.

We are going to cover everything you need to you the next 7-8 months. This Outdoor Grow Calendar includes average day lengths and temperatures for the southern half of the country, including Hawaii.

A Few Notes:

  • Averages are based on Los Angeles, Houston, and Miami
  • Southern West Coast growers can expect the most sun and the coolest average temperatures year-round.
  • Central areas will have the hottest summers, while the Southeast will experience the hottest spring and fall.
  • The shortest summer days are in Hawaii.

February

Average Day Length: 10 hours 30 minutes to 11 hours 40 minutes
Average Temperature: 49 degrees to 80 degrees

Hawaii:
Average day length: 11 hours 15 minutes to 11 hours 45 minutes
Average Temperature: 67 degrees to 81 degrees

Time to buy seeds! For most of the southern United States, the threat of frost has passed and it’s just about time to start growing. Because of the extended growing season in some areas of the south, it’s safe to choose sativa dominant plants. If you opt for an Indica, make sure you consider hot your summers generally become.

Read the article "Best marijuana seeds for my climate" if you're not sure what seeds grow best in your area

You can also begin sprouting your own seeds indoors until it is warm enough for your plant to go outdoors. Seedlings prefer a temperature between 68 and 77 degrees. While some areas, such as Hawaii and southern Florida, boast February temperatures like these, your plants will also need 18 hours of sunlight. So, you are going to want to invest in some CFL grow lights until the days get a bit longer.

Sprouting cannabis seeds

Start sprouting your seeds

For more information on germinating your seed indoors, read “how to germinate marijuana seeds”.

You should also take this time to prep your soil. Now is the time to loosen it up a bit by adding compost and worms.

March

Average Day Length: 11:30 hours 30 minutes to 12 hours 30 minutes
Average Temperature: 50 degrees to 81 degrees

Hawaii:
Average day length: 11 hours 45 minutes to 12 hours 20 minutes
Average Temperature: 68 degrees to 82 degrees

The warmest areas of the United States are starting to feel like summer, and the interior is no longer at risk of frost. Assuming you already have your seeds, you can begin sprouting plants in the window sill this month. Your plants need to be receiving at least 12 hours of sunlight, so if the days are not quite long enough yet, add a lamp an extra hour a day to make sure they receive enough.

Sprouting cannabis plant in the window

When sprouting your plants, make sure you get enough hours of light

If your plants do not get enough sunlight, they may start flowering early – and you do not want that.

If you decided to use a mother plant, spend some time tending it. It needs to be ready by the end of the month if you plan on using your clones outdoors.

April

Average Day Length: 12 hours 30 minutes to 13 hours 30 minutes
Average Temperature: 55 degrees to 84 degrees

Hawaii:
Average day length: 12 hours 20 minutes to 12 hours 55 minutes
Average Temperature: 70 degrees to 83 degrees

April raises the temperature just a bit and lengthens days significantly (except in Hawaii). You’ll notice the longer days around the middle of the month, with most southern areas reaching 13 hour days by the end of April. At this point, you won’t need those lamps in your windowsill anymore. Make sure they are receiving as close to 13 hours of sunlight as possible, and your seeds should easily sprout.

In fact, if you live in the Southeast, it’s probably safe to take your plants off the windowsill and into the fresh air. The Southeast tend to have the warmest spring temperatures in the southern half of the United States. As a rule of thumb, if it’s 70 degrees, you’re probably okay to let them sit outside during the day. Remember to bring them indoors at night!

Sprouting cannabis outside

You can sprout your seeds outside in the sunlight now

If you created a mother plant in late February, now is the time to start making your clones. Read the article "How to make clones" for more information

May

Average Day Length: 13 hours 10 minutes to 14 hours 15 minutes
Average Temperature: 60 degrees to 87 degrees

Hawaii:
Average day length: 12 hours 56 minutes to 13 hours 20 minutes
Average Temperature: 71 degrees to 85 degrees

Spring has arrived – although, in some places, it already feels like summer. Go ahead and place your plants outside permanently.

Plant your autoflowering seeds by the middle of the month. By that time, they’ll have plenty of sunlight to grow, and the temperature is just right. You’ll be ready to harvest the beginning of August. As a note to any Hawaii growers, do not choose strains that require higher than average amounts of sunlight for outdoor growing, as Hawaiian summer days are the shortest in the country.

June

Average Day Length: 14 hours 15 minutes to 14 hours 45 minutes
Average Temperature: 60 degrees to 91 degrees

Hawaii:
Average day length: 13 hours 20 minutes
Average Temperature: 74 degrees to 87 degrees

June is when outdoor marijuana plants grow the most – specifically between June 18th and June 24th. Autoflowers begin to develop flowers, and non-autoflowers grow faster.

June is also when Hawaii starts to experience the shortest days in the country, as compared to California, where outdoor plants receive up to 90 extra minutes of sunlight.

July

Average Day Length: 13 hours 30 minutes to 14 hours 20 minutes
Average Temperature: 65 degrees to 93 degrees

Hawaii:
Average day length: 13 hours 5 minutes to 13 hours 20 minutes
Average Temperature: 75 degrees to 88 degrees

The hottest month of the year produces large flower clusters on autoflowers while your non-autoflowers may show their first pistils.

First pistils grow calendar

If you used regular (non-feminized) seeds, now is the time to look for pesky male plants. Watch those side branches for flowerheads at the bottom of the side branches that look like two small balls resting on a short, thin stem. If you see them, quickly remove them. Females, on the other hand, will have drop-shaped calyxes with two white pistils protruding from them.

August

Average Day Length: 12 hours 45 minutes to 13 hours 50 minutes
Average Temperature: 65 degrees to 95 degrees

Hawaii:
Average day length: 12 hours 30 minutes to 13 hours 5 minutes
Average Temperature: 75 degrees to 89 degrees

Your autoflowers from May are now ready to harvest! Go ahead and cut off the flower heads and hang them upside down in a dark place to dry. Don’t try to rush the process by messing with the temperature- dry them at room temperature.

It should only take about 10 days. Test for readiness by seeing if the branchlet cracks when you bend it. Read my article article "How to harvest marijuana plants" for more info

drying cannabis

Start drying your autoflowers

It also may be time to harvest your non- autoflowers, since the days have dropped below 14 hours and they must be harvested before they reach 13. That means, Hawaiian and Southeast growers have a shortened outdoor growing season and must choose autoflower strains with short growing cycles, since this date comes quicker for them.

Once the days drop below 14 hours, non-autoflowering plants start their last flowering phase and begin to die. If you are in an area with limited amounts of daylight, you can bring them indoors and use lamps to extend the growing season a little bit longer.

For non-autoflowering (photoperiod) plants that are not ready to harvest, you’ll see more pistils and flowerheads. Keep them protected from the wind and dry by building a shelter or bringing them inside if they are potted. You can also stabilize them by using bamboo sticks.

September

Average Day Length: 11 hours 50 minutes to 12 hours 50 minutes
Average Temperature: 64 degrees to 89 degrees

Hawaii:
Average day length: 11 hours 57 minutes to 12 hours 30 minutes
Average Temperature: 75 degrees to 89 degrees

Fall comes at the end of this month, but some parts of America may not notice, at least temperature-wise. However, the shorter days near the end of the month are a clear indicator that the growing season is nearly over.

cannabis plants ready to harvest

Plants will be ready to harvest

Many plants will be ready to harvest during this month if you haven’t already.  Read my article article "How to harvest marijuana plants" for more info

October

Average Day Length: 10 hours 50 minutes to 11 hours 50 minutes
Average Temperature: 60 degrees to 86 degrees

Hawaii:
Average day length 11 hours 20 minutes to 11 hours 55 minutes
Average Temperature: 74 degrees to 87 degrees

Autumn is here and the outdoor growing season is officially over. While plants in most of the southern United States should have already bloomed, there may be some that finish up this month. If your plants are still growing at this time, be especially careful of cold, wet temperatures. This can cause bud rot, which can ruin your harvest. The heartland of America is most at risk for this.

If you notice any signs of bud rot, harvest immediately – some is better than none. Read more about bud rot the the article "How to prevent Bud Rot"

bud rot on cannabis plant

Be careful with bud rot on your plants

There are many climate regions in the United States, each impacting your plant’s growing season. The important thing to remember in the southern half of the United States is that marijuana loves sunlight. Growing outdoors means you need to time your growing for when it can receive the most of it.

Do you grow in the southern half of the United States? Did we leave something out?

Let us know in the comments, and we’ll update this calendar. Together we can share knowledge to grow the best marijuana in the USA.

Here’s to a great harvest!

Hi Robert can you give me times for Australia grow times please


By Bill on 23 February 2017

Yeah, what a great idea! Grow times as suitable for the sub-tropics where the average temp, along the coast, is warm to hot... say upper 20's at night and low 30's in daylight. Any info/suggestions/outline very welcome.


By Roy on 21 July 2017

Thank you for all the info. .An Australian grow diary would be great ! Meanwhile adding 6 months to the given dates should do it

I am new to growing maria, and have read the info re iron deficiency. I know that a good "cure" for iron deficiency in people is to place two large rusty nails in an apple, leave for an hour, then eat the apple. What would happen if I planted a rusty nail or two next to each plant?

hello,
it would be great to see a calendar for the southern hemisphere or eastern australia. thanks in advance


By David Manevich on 23 February 2017

As always Robert Great information. Anyone not a member of Bergmans Lab should definitely consider joining. Besides all of the knowledge ive gained from yourself, your staff is very knowledgeable and helpful also. I can not stress the value of all this experience in one place i highly recommend Bergman's Lab to anyone interested in learning almost every aspect of growing top quality cannabis on thier own. And as far as price is concerned im currently on social security disability and had no problem at all affording it. The cost verses the info and support is the most valuable ive found. And I looked for a long time before desiding on Bergman's Lab for my growing knowledge.
Thank you again Robert I just cant say that enough.

Help-my new germinations-white widow and blueberry are coming to life as dwarves.Seeds 6-9 mths old, indoor soil germ. Plants pop in 3-4days, but now pencil lead size stem, lvs size of cotolydons.December blueberry was all I could hope for-sturdy, tall, flowered. What is up?


By latewood_ILGM on 24 February 2017

Guy,

There are many issues that can cause similar problems to what you are having. It would be hard to give you an informed answer with such little jumbled nit of info.

Why don't you join our support forum, and then we can do a Q and A, and help you out?

You say "Female plants, however, will have drop-shaped pollen sacks" (two places).

Female plants don't have pollen sacks.


By latewood_ILGM on 24 February 2017

Actually Fem seeds can develop hermaphroditic traits and can indeed produce pollen sacks


By Nicole M. on 23 February 2017

It would be so helpful to have a grow calendar for the east coast of Australia (Southern Hemisphere). We tend to get forgotten.... Thanks ☺️


By latewood_ILGM on 24 February 2017

All you have to do is contact your local agriculture agent, and he should be able to give a time frame. Just ask for a schedule for Tomatoe's

I'm from the northern ALaska, what strain should be looking for?


By Roy ILGM on 6 March 2017

Hi Gordon, I imagine it's a bit cold to grow properly outside at your location. But anyhow I'd say go with Indicas or perhaps even autoflowers so they have a bit of Ruderalis in the genetics.

Hey Jeff,

What do you mean hms lights? Do you mean HPS lamps? I want to invite you to download and read our free grow bible. Also; join our support forum at ilovegrowingmarijuana.com.

Happy growing 🙂

Thanks for sharing the process Marijuana grows, it is a long process. The infographic has summarized clearly.

What about Florida? I know we're considered the southeast but we're a totally different animal compared to the rest of the southeast with extreme temps (we've already hit 100 and it's not even June) and daily thunderstorms.


By Brent on 21 July 2017

I live in the same geographic area, and I use indoo/outdoor screen over my plants for two reasons. Firstly, the screen blocks some of the rays of the sun to keep cooler. Secondly, when torrential rains come it breaks up the pelts into drop, so it doesn't beat the plant to smithereens. In conclusion, paint the exterior of the pot white to keep the roots cooler. In conclusion, I hope these suggestions will help you have a prosperous grow


By Hosey on 22 July 2017

You can harvest some but to revert back to vedge the easiest way is to go back to vedge light schedule. I've done it but don't wait too long. When the Trich's turn it may be too late.

This is great very straight forward and very informative, nice to have it all laid out on one page. Thank you


By Hosey on 22 July 2017

Hi, I'm glad I found you. In Central MN. We can't grow good photoperiod plants. By the time we get to 12/12 light/dark and they show sex and start to bud, We get frost. We can start indoors early and put out later but frost always takes the girls before they are ripe. We do love our auto flowers though !! The downside to growing outdoor in MN. is that there is a LOT of Feral weed out there at the old farms. That crap pollinates our high dollar gals and the seeds produce low to no quality weed. We keep pushing on though !!!

I live in W.V. Is it to late to put out auto flowering seeds know.If not what's the best ones to use.Thank you


By Roy ILGM on 24 July 2017

Hi Mark, you're a bit late but you can try to squeeze in an auto grow. The Super Skunks have the shortest flowering time but it's not far off from the rest.


By latewood.ILGM on 24 July 2017

Mark.

Be prepared to put a small structure wiht a frost nlanket around your plants if it get too frosty before they are ready 🙂


By Henry Phillips on 26 July 2017

I live in the direct middle of South Carolina. I always plant my seeds in 5 gallon pots filled with pure cotton gin waste, no nutrients needed except pot ash and trace elements, with outstanding results. I plant the last week in June outside. This way my plants have more youthful vigor when flowering. By the the time the photo period shortens they are perfect. what are your thoughts for improvements? By the way, the waste I use we expelled in the 60's and 70's. I have been growing cotton with my dad for 40 years.


By latewood.ILGM on 27 July 2017

Henry,

I don't know what to tell you. That is an interesting medium you are using. Perhaps you could read up on fermenting supplements.

Join our forum and share your ideas. Happy growing 🙂


By Tuck on 28 July 2017

Hi Robert. What will happen if your plants flower early


By Roy ILGM on 7 August 2017

Hi Tuck,
Not sure what you mean by flowering early. Plants flower when the dark period gets 11-13 hours long. What genetics are you using?
I suggest you join out support forum for guidance and to allow us to see what you are talking about and allowing us to give a more informed answer. 🙂

I have planted four plants Misty Kush approximately three months ago they are very healthy 3 to 4 foot tall and 3 feet in diameter . Three of them are still in the foliage stage and one has started flowering for approximately two weeks . I would like some information on transplanting them. I gorilla grew them in a meadow deep in the forest now the forest is being cleared commercially and I may loose them. Can they be transplanted successfully to 5 gallon bucket's and if so do I need any treatment for shock or special soil .


By latewood.ILGM on 1 August 2017

Maxx,

If a plant is 3' diameter, then you would have to dig a 4' diameter area around the plant to not damage the roots. Transplanting into 5 gallon buckets would therefore most likely not be viable. You could use Panda plastic and make big grow sacks and back fill with a potting mix, nursery mix, or something of that nature. Best for you to look up how to transplant a bush in your yard to show you some guidelines. Peace

HEY! I didn't get my grow bible. What's up????



By Ken K on 14 August 2017

Can you please send info for growing in the central valley of California the temp. gets to be 110 degrees in July and sometimes in June and August also. Fresno County


By latewood_ILGM on 18 August 2017

Ken Kon,

that is some rough environment. UNfortunately we are not set up for that type support here in the comment section of the blog.

We invite you to join our ILGM forum. We have many expert growers out your way willing to share their ideas and concepts for dealing with desert and mountian temp changes.

Awesome report


By KEITH on 18 August 2017

Any tips on moving outdoor plants (in planters) inside for safekeeping during Budding season?


By latewood_ILGM on 28 August 2017

KEITH,

I recommend you join out forum at ilovegrowingmarijuana.com, and we will guide you through this process. The best advice I can give you here and now is; Make sure you get adequate lighting for your plants if moving them indoors. 600-1000 watts for every 4'x4' space needed. i.e. If you have 6-8 plants, you will need 2, 600-1000 watt HID lamps to make comparable lighting to the Sun.

Happy growing


By Brad on 23 August 2017

I live in Central IL and I was wondering when is the best time to havest they are Train Wreck, Headband,and Presidential OG Kush I bush them so they would blend


By latewood_ILGM on 28 August 2017

Brad,

You harvest by the readiness of the trichomes. There are 3 levels of trichome development.
1. Clear. _ Proof of a vessel to contain THC
2. Cloudy - Presence of fresh THC
3. Amber - Amber is fully potent THC and starting to decay slightly.

Growers must make the choice of what % of clear, cloudy, amber trcihome development that creates the effect thhe grower is looking for.

More clear and cloudy = up high
more cloudy and amber = medicinal, and sleep "couchlock" effect. 🙂

Join our forum at ilovegrowingmarijuana.com for many more opinions. 🙂

By steveb on 24 September 2017

the times for putting out your plants and harvesting need to be adjusted slightly. I'm in grow z 3b. i have frosts up here tis' mid june and 1st frosts starting mid sept. this year i have both indica and sativa dominant strains and they will all finish at the same time. its sept 24th and I'm guessing they will finish mid oct. as they're just starting to bulk up the buds. I'm growing in a greenhouse so ill be able to continue to grow my plants to maturity but some outdoors, unprotected won't. also we just hit 12/ 12 day night cycles which also delays budding up here. my suggestion on very northern outdoor growers is either grow autos or find indica dominant fast flooring strains so your plants finish sooner but even then its best to get them out as early as you can and put up some type of protection or start them earlier with the same amount of light inside as you have outside so you don't induce early budding when they're put out. good luck!


By Jessica silverio on 1 October 2017

Hello im a first time grower and a good friend gave me a seed from the gorilla strand and it was planted mid june she gave it to me in the begining of july it was just a lil baby now its the first of october and i have it in a grow bag out side and i feed it every other 2 days fish fertilizer and every other2days plain water so i alternate 2 days fish fertilizer and then 2 days later plain water so on and so forth.. Thats my routine and so far she is a beauty smells good too... Her flowers came out the mid of Aug , so my concern is the cureing stage? My friend said she will be ready by late Nov but i see her not growing n e more do u think its still ok to place her in a bigger location? Or just leave her alone till shes ready? Oh and im in southren california so i dno how the harvesting dates work over here.. Thank u for ur time.. In need of some tips and tricks



By Joe on 6 October 2017

This is a comment for your northern outdoor grow calendar. I'm growing in Southeastern New Brunswick, Canada. Your seeds did well planted directly (ungerminated) in pots outdoors late May, though it was a wet and cold spring. From 5 Gold Leaf and 5 Purple Haze feminized seeds, 4 of the Gold Leaf sprouted (one did not) and all 5 Purple Haze sprouted but one stopped growing before the cotyledon leaves fully developed, the seed apparently lacking in vitality. Plants were transferred from pots to "field" mid June into soil treated with compost and slow release fertilizer pellets. Plants grew steadily with large differences in phenotype, 7 of the plants being about 1.2 m tall, only one plant achieving 2m (Gold Leaf.) A common water soluble fertilizer (Miracle Gro) was used in July and late August (with initial development of bud) as per product dilution instructions, about 1.5 L applied per plant. The last days of September brought 3 days of increasingly hard frost, first night 3 C, second night 2 C and third night -1 C. Plants were covered only on the 3rd night. Though there was light ice on the plants after the first and second nights of frost there were no detrimental effects to the plants. After the third night of frost, all bud contacting the cover cloth (old sheets) had pistils turn brown and buds bent as if under weight, but they came back well during the day. After the frost nights, the temperatures moderated and we are expecting to achieve at least a week of moderate temperatures, some wet and some sunny weather, and sufficient time to ensure a good maturity to the bud. To achieve proper maturity of the bud in this climate, this year, guard against the brief interval of frost seemed necessary, and well worth the effort. Sheets used to cover the plants were darker coloured and not obvious. Gold Leaf and Purple Haze, the seeds recommended by ILGM for my area, seemed to be good choices for hardiness, reasonable grow time, and happily with the best production of bud I've succeeded in growing yet. Thank You!

This is amazing? How. Can you mail cannabis seed to the US?

Ive had it done and would very much like to have it done again.



By New Grower on 11 October 2017

Hello: I need help. This is my first grow. I'm in the Washington DC area and I started rooted hybrid clones outside at the end of June, I know....late. Well, I fed them with compost water and some organic nutrients. Well, it's October and the pistals are turning brown and the tricones are also turning, but aren't as abundant as I have seen them in pictures. I've made a grow closet so that I can bring them in and put them thru the 12/12 cycle......but I'm kinda lost. Should I flush the soil first? Should I bring them in now even though the temps are still in the 60's & 70's? It is still time to do the 12/12????? Help!!!! I don't want to lose them and I'd like them to be as potent as possible. What do I do now???


By latewood_ILGM on 12 October 2017

New Grower,

It sounds like your plant is about finished. I can only guess because this is a comment section of the blog. I suggest you join our support forum support.ilovegrowingmarijuana.com

We are set up there to do grow support. I will say that you don't wait for more pistils if the plant is finished, you harvest. Trichome production is attributed to excellent lighting and a strong nutrient regimen and microbes in the soil. Sounds like you have some things to consider in order to produce more trichomes next time. See you in the forum. 🙂


By Grass Chief on 9 November 2017

Thank you very much for ILGM and Harvesting guides. If the marijuana plants aren’t getting enough sunlight set a lamp over your plant a few extra hours each day.


By Bill on 17 November 2017

Could you comment on when would be a good time to go from pots/containers to in ground. I'm in Grass Valley Ca., but hopefully helpful for all areas. Great info. Thanks


By latewood_ILGM on 22 November 2017

Bill,

You can transplant into the ground after the last frost. Some people go by size. I would have my plants at least 2 foot tall before transplanting outdoors.

Perhaps you would enjoy some Q and A in our support forum 🙂

By Cyclingmasterseller on 4 January 2018

Need to acquire seeds that "will for sure" turn out to be smelly. Is there a controlled, stable, strain that will produce, from seed to harvest, a very heavy scent of perfectly strong, pungent aroma?


By Mike on 5 January 2018

So far I had 40% failure rate. Long stems with small leaf then it withers. Not sure why after successful germination and planting, keeping soil moist light in close proximity. Too cool to grow outdoors keeping plants around 72 degrees F


By IL Grower on 20 February 2018

my first planting last year did that. to much sun and not enough wind. second planting as soon as they sprouted I moved outdoors. install a small fan. I have fan with my timer so it doesn't run 24/7

I read above about someone painting their pots white to help keep roots cooler. I use white 5 gallon buckets, then drill 1/8 inch holes on the sides right at the bottom every 3 or 4 inches. this allows heavy water amount to drain well. I also plant it the to side of the handle so that when I want to pick them up to move them I don't damage the plant. if your plant gets top heavy you might need to water right before moving them. the handle also allows me to turn the plant 180 degrees daily so that I get the most even amount of sun all the way around the plant. I monster cropped my plants last year so the height of the plant helped keep them from tipping in the wind

Hello blogers, I have been growing for a few years outdoors, just recently I have been trying to grow indoors. My main problem I think is growing the seedling. Ive seen so many pictures of plants at the 30 day period and they have so many leaves and branches on them. When I try to do it I get really long stems with very little leaves and branches. What the hell am I doing wrong?


By Tony on 20 August 2018

By latewood_ILGM on 18 April 2018

Dave,

!st. I apologize for the lateness in answering you. We had some tech issues, and I posted to you but, the post did not publish.

It appears to me that you have the wrong lighting for seedlings or, the lamp is too far away from the top of your seedlings. For the best result you need a T5 lamp 1-2" above your sprouts, this keeps the node spacing tight, and develops a strong start to seedling stage. Also; You need a small reciprocating fan to move air and the stem to strengthen it.

I suggest you joinus at support.ilovegrowingmarijuana.com and allow our friendly membership and experts guide you. You can supply pictues and get strng grow advice at the forum where we are set up to teach you from start to finisah.

Happy growing 🙂

Hey fellow stoners/growers, I have a question for those of you that live in Southern Africa... How easy is it to get auto flowering seeds for outdoor growing delivered to Zimbabwe? I'm an avid grower and have followed most of the steps and tips provided in the grow bible (with a few modifications of my own) for a couple of years now and have always had a huge success rate, however I'm now looking to do autoflowering plants as they are quicker to mature. Any help will be most appreciated...


By latewood_ILGM on 18 April 2018

Shaun,

We cannot hazard a guess as to how well the shipping process will work in Zimbabwe. I can advise that we do our best to get shipments to you and with that said; I suggest you buy the shipping guarantee, so that if anything goes wrong and your parcel is confiscated, ILGM will replace your order. I do not think that we will replace an order without the extra charge; I am sorry to say. Either way I believe it worth the extra fee in order to guarantee your investment.

Happy growing, 🙂

What an awesome guide for the weed growing seasons, its rare to actually read not skim through a whole guide like this but especiallyt since i just moved to a place where is impossible and the seasons are not stable, been a great read


By BuddingTrees on 12 July 2018

Real growers never use autoflower! We grow feminized or regular seeds! It would be awesome if you didn't insist on autoflowers, they're junk and you won't find them in dispensaries in Cali, Oregon, or Colorado for a reason!


By Pags on 29 July 2018

Thanks for that!!!
