How To Germinate Cannabis Seeds

How To Germinate Cannabis Seeds

Germinating cannabis seeds paves the way for healthy development of the plant, so it is very important to make sure that every need of the seed and germ are fulfilled. This article will describe what seeds are, and how to germinate marijuana seeds.

Like every plant, marijuana begins with a seed, which requires water to grow. The seed houses the entire plant and can survive the first few days with a reservoir of food. While it’s germinating, the seed can turn this saved food into sugars, which it uses to grow.

We will uncover the process of germinating seeds as well as perfecting the conditions for young seedlings. Additionally, I will go through the different methods of germination, as well as the advantages and disadvantages of each method.

What are cannabis seeds

Buy Cannabis SeedsLike every plant, marijuana begins with a seed, which requires water to grow. The seed houses the entire plant and can survive the first few days with a reservoir of food.

While it's germinating, the seed can turn this saved food into sugars, which it uses to grow.

A seed increases in size and breaks open when it's received enough moisture. A germ opening forms, allowing the root to go through, and it goes down into the ground.

Because its downward motion is due only to gravity and not some other force, the root will always grow downward--even if the seed is positioned in a different way. Consequently, the stem consistently grows opposite to the root, so it will always grow upward.

How to germinate cannabis seeds?

Germinate Cannabis Seeds MethodsGerminating cannabis seeds methods come in many different shapes and sizes, each with its pros and cons. Rockwool cubes, soil, or peat pellets are all suitable locations for the germination process.

As long as the amount of moisture and temperature are right, they should all achieve the same thing in the end. Let’s start out by going through my favorite method of germinating cannabis seeds: water germination coupled with soil germination.

I first submerge the cannabis seeds in water and let them soak for 24 hours. This assures that there is the right amount of moisture to begin germinating. The seeds won’t absorb too much water unless they’ve been soaking for 7 days or more, so don’t be concerned about that.

Pour tap water (no added nutrients needed) into a cup and let it sit for several hours, allowing it to get to a room temperature. Even if the seeds haven’t broken open, the seeds will have begun to germinate after 24 hours.

Germinate seeds in soil

Germinate cannabis seeds in soil

Because soil makes a cushion of water and nutrients, it is very easy to germinate cannabis seeds in soil. You should use mildly fertilized potting soil or a seed-starter; the pH level of proper soil should be approximately 6. Read the article Best Ph levels for more about pH

Seeds are delicate and can negatively respond to an overdose of nutrients. Potting soil should contain the right amount of nutrients to work for two weeks or so, and it is available in most garden centers.

After putting soil in the pot, (one pot per seed), you can use a pen or pencil to make a quarter-inch-deep hole. If a root has already popped out of the seed, you can help it grow faster by making sure that part faces downwards.

Once the seed is in the hole, make sure it is topped with soil; don’t push down the soil, however, since this will occur automatically when you water it.

All this will let the seed germinate, and you’ll soon find evidence of your work when the plant pops out of the soil in a few days or a week. Below the soil, many new roots will grow from the main root and a solid system of roots will form.

Watering seeds

How To Water Marijuana Seeds?Like all living things, water is the most important element in germinating seeds. For this reason, you need to be sure that you feed your plants the perfect amount of water. If you water it too little, the plant will try to conserve energy in order to survive, and won’t grow to be very large.

If you water it too much, the roots will not get enough oxygen, making the roots rot and the plant above to go limp. The soil could also attract mold and other harmful bacteria.

The way to make sure your plants receive enough water, add water until you see it seeping out from the bottom. Even though the seedling doesn’t absorb this much water, it evaporates very quickly. Consequently, this amount will just last for several days.

Light and temperature

Best Temperature for Cannabis SeedsLight is the second most important ingredient to growing a healthy marijuana plant. Light gives plants the ability to form sugars from carbon dioxide and water. These sugars are used to power the plant’s growth. This is referred to as photosynthesis.

The amount of light is also very important, as it affects the precise way in which plants grow. For instance, if plants receive too little light, they will only grow in height and not in breadth, and won’t produce many branches.

This is due to natural selection in their natural habitat; if a plant can grow above the others, it has a competitive advantage because it will absorb more light.

Plants that already have access to enough light will also achieve growth in breadth. More branches and therefore buds will crop up, which is ideal for these cannabis plants. If you keep light throughout the day (both day and night) you will accomplish a consistent temperature and can maximize your plant’s growth.

Download my free marijuana grow guide at this link for more growing tips

Placing your seeds in containers under fluorescent lights is best, since the lights do not use too much power and don’t emit much heat, allowing you to place them quite near the plants. Although the seeds don’t actually need the light at this point, an immediate exposure to enough light once they pop out of the soil will help them develop best.

The temperature should remain near 73 degrees, but if it’s too hot then simply move the lamp further away from the plant. Wrap plastic wrap around the pot so all the extra moisture cannot escape, thus creating the perfect humid climate for the seeds to germinate.

The plants should start popping up after 3-7 days, as long as you are closely monitoring the temperature. You should remove the pot’s “lid” (plastic wrap) as soon as you see the first sprouts; then have the lamp on at intervals of 18 hours on, 6 hours off.

Germinate seeds in rockwool

How To Germinate Cannabis Seeds in RockwoolRockwool is mineral wool that comes from volcanic rock and other materials (basalt and limestone, for example) and provides the perfect environment for the growth and germination of plants.

The stones are formed by heating them up to 1500 degrees Celsius, turning them into molten lava, which is then quickly spun, releasing drops of lava that solidify to form threads.

These threads are further processed with compaction, curing, and cutting, turning them into the Rockwool forms that we know (including slabs, blocks, and plugs).

Download my free marijuana grow guide at this link for more growing tips

Starting seeds in rockwool

The main difference in this process is the addition of fertilizer; rockwool doesn’t contain the nutrients that soil has, so you’ll need to add a bit of fertilizer (TDS should be around 600ppm ) when you start seeds in rockwool cubes.

Additionally, the pH level is 7.0, which is too high for optimal germination, meaning you’ll need to lower the rockwool pH.

This is achieved by placing the ockwool plugs in water (pH value 5.5) for a full day, allowing it to bring down the Rockwool’s pH level.

Although it can be a bit trickier, there are some pros to using rockwool instead of soil. First, while transplanting, rockwool cannot have a harmful effect on the roots (which can occur when using soil). Of course, pH and TDS meters are necessary for successful rockwool germination. The rockwool cubes are available by online order via Amazon.

Germinate seeds in peat pellets

How To Germinate Cannabis Seeds in Peat PelletsPeat pellets are simply compressed peat within a bag made from mesh; this peat enlarges when you add water and turns into a sort of container.

With the pH level of 5.5 and the TDS at 625, peat pallets create the ideal environment for germinating your cannabis seeds and growing your plant.

You can also put the peat pellets straight into the soil or rockwool right when you start to see the roots popping out, thus avoiding damage to the roots altogether. Peat pellets are also available for online order via Amazon.

Germinate seeds in water

How To Germinate Cannabis Seeds in Water?How to germinate seeds in water? If you allow marijuana seeds to remain in water for 24 hours, the seeds can be pre-sprouted. This allows you to view the seeds, and it ensures that they have plenty of moisture for starting the germination process.

Additionally, germinating cannabis seeds in water is a faster process than planting them directly into the soil.

This method isn’t perfect, however, as it means the seeds will need to be picked up (whether or not a root is already emerging). This root is extremely delicate; if harmed, it could be detrimental to the development of the plant, so you must be extremely cautious when touching a seed with an emerged root. To save time, plant the seed with its root facing down.

Although others might disagree, I have found that this method is the best one, so I’ve continued to use it for years.

Germinate between cotton pads

How To Germinate Marijuana Seeds Between Cotton PadsGermination cannabis seeds between wet cotton pads is also a suitable method. Like with placing the seed in water, this process ensures that the seeds will have plenty of moisture.

On the other hand (also like the water method), the seeds will need to be picked up and moved, thus risking harm to the root. If proceeding with caution, however, this should not present many problems.

In 2 to 5 days’ time, the roots should be visibly growing out of the seeds, at which point you should move them. This is simply done by removing the cotton pads with caution and placing them into the soil or rockwool, either with your fingers or tweezers.

Germinate seeds outdoors

How To Germinate Marijuana Seeds Outdoors?I would not recommend you to germinate cannabis seeds outdoors, as it easier to maintain the suitable temperature inside, as well as the level of water and light. This applies even if you will actually grow the plants outdoors. Outdoors there can be variants in rain, clouds, and other things that can negatively affect the germination of your seeds.

Germinating inside also allows you to end up with bigger plants and a greater yield since you can start the growth earlier.

Germinating seeds outdoors means that you would have to wait until the final frost has passed before you can begin. You can easily grow your plants outdoors by germinating inside and then moving the plants outdoors once they are bigger and stronger, having begun with a healthy germination period. These plants can endure much more than young seedlings that are germinated outdoors from the beginning.

Download my free marijuana grow guide at this link for more germination tips

That being said, it is possible that germinating inside is simply not possible or not worth the inconvenience to you. In this case, you can begin germination in the location that you plan to fully grow the plants. This provides a certain advantage; since you are not moving the seeds, you’re also not risking accidental destruction of the root.

Before planting, dig holes (6x6x6 inch) in the ground and fill them with potting soil. This will provide the seeds with enough nutrients for the beginning. After that, create a small quarter-inch-deep hole and plant the seed inside. Make sure that you soak the soil in water. You might even want to add some more water in a few days if the weather is particularly warm.

Make sure to plant the seeds an 3 feet apart. Under the right circumstances outdoor marijuana plants can get very large and you do not want them competing with one another Note: if you won’t be growing the plants in your personal garden at home, some good locations for weed growing include corn fields and ditches.

Speed up the process

Fast Germinating Cannabis SeedsYou can speed up germination and kill infectious agents by soaking the seed for 12 hours in a 1% hydrogen peroxide or compost tea solution.

First, position the seeds in sterile planting mix, planting pellets, rockwool, pasteurized soil, or Oasis cubes at about a quarter of an inch deep. Then, water the seeds with a 0.5% hydrogen peroxide solution with an added bloom fertilizer at about 25% strength.

Try to keep the medium consistently moist by, for example, covering the whole apparatus with a dome to ensure constant humidity. Also, try to keep the medium out of the sun and at a temperature of 72*F (22*C). Depending on the age of the seed, they should germinate between 2 and 10 days (older seeds take longer than younger ones). Keep a firm light on the seedlings or else they will stretch out.

Download my free marijuana grow guide at this link for more germinating tips

For outdoor plants, the seeds should be planted during the season in which corn is planted in your area. You can hasten the season with row covers, but this can cause vegetative growth and flowering problems if there is a critical dark period involved. This happens occasionally when the plants are put outdoors early in the season.

The seeds need to be planted about a quarter of an inch (6 mm) deep on tilled soil or simply drilled into untilled soil. They need protection from weeds and overgrowth, but when they reach unobstructed sunlight, they will soon take over the entire canopy.

Many strategies for germinating marijuana seeds are available to you; you simply have to choose which one is easiest for properly maintaining the needed moisture and temperature level.

Thanks! I need all the help I can get. I don't have any experience growing indoors!!

By medMUser on 20 February 2016

If you put the new root tip facing down with the pointed end up, you'll have better results. Less stress on the new sprout this way. When the seeds sprout, if you have ever noticed, the root tip will ALWAYS grow up for a short ways, then will curve back down toward the bigger end. That's why it's best to always put the pointed end up.

To verify, put some seeds in a moist paper towel with the pointed ends facing the same way. Put a few with the big end up & some sideways for a control. Put the seeds in the moist paper towel into a baggie, then hang over your low heat sprouting source. The results will speak for them selves. Just be sure the seeds can't move around, the baggie is straight up & down, not lying flat & some of the seeds are pointing straight up.

The above paragraph is an old hippe sprouting trick to keep the roots from going crazy if your seeds germ earlier than anticipated.

Not trying to argue, you can place your seeds any way you want. I am just saying that 'pointed end up' is the most efficient method.

Hi Robert can you tell me what is the best type of Fluro light for germination, I'm
using rockwool and trying to grow indoors in a tent using water hydro instead of
soil, I have Gold seeds, can this be achieved using water instead of soil with these
Thanks Peter.

By Chris on 4 February 2015

Peter, the best type of fluorescent lights for germination and vegetation period are T5 HO (high output) with a color temperature of 6500K

By Icebox grower on 6 February 2015

Second grow started...I learned a lot with my first grow, not a positive experience with seed germination. This time around I read intensely and studied your Grow Bible, especially the germination section. I decided to use two methods together, glass of water soak for 24-28 hours, then planted seeds in jiffy pods in a grow dome. On day 4 in the grow dome 1 seed sprouted, on the fifth day all seeds had sprouted, which was this morning! I'm stoked to say the least! I bought my White Widow and Blueberry seeds from here and I was holding my breath that I'd get 100% germination results, which I have. Thank you for stellar seeds and stellar growing info! Kudos!!!

By Mike on 7 February 2015

what is the best way to store remaining seeds to keep them fresh and viable for my next grow.???

By Robert Bergman on 3 April 2015

Hi Mike,

It's best to store them at a cool, dark and dry place. A fridge is perfect


By SAM on 16 February 2015


By Steve on 19 February 2015

My favorite germination method is water soaking (less than 24 hours) then transfer to moist paper towel. That works for me 90% of the time.

By Clayton Parsons on 23 February 2015

Enjoy reading grow guide. Like your weekly tips and tutorials. Great service on seed orders. TY

By Jasone on 2 March 2015

In your book you talk about the white light being 4" from the leaves. The light is 240 w. For how long does this last till I move the plants to the yellow light?

By latewood on 29 May 2015

Not sure I know what you mean by 240w lamp. The white light, or the yellow light? You induce flowering when the plant is no more than half way up to the lamp, when lamp is at highest point allowed by your space.

By TJ aka Mr. Grow good on 12 March 2017

Yellow n red lights turned to 12 on 12 off will let ur plants no that the end of summer is near and let's ur plants no it's time to start flowering. use a light for veg. that has more blue lumins this is great for veg. stage

By gary on 4 March 2015

hi Robert. well after much anticipation and worry, i finally have 2 seedlings. i'm sure there will be others very soon. my question now,,,,light requirements, and how far away should the light source be, to prevent spindly growth. that has always been my biggest problem in the past. any help would be greatly appreciated.


By Robert Bergman on 3 April 2015

Hi Gary,

Put the lights as close as possible but don't let temperatures exceed 76 degrees. Fluorescent lights are great for seedlings...


By ken on 17 March 2015

i grow at 8000 lumens a square foot and never have plants that streach, biggest thing is to have proper light

By Danielle on 25 April 2015

When is it a good time to start planting in So Florida? I'm having problems with my plants are always stunted these pass two times I'm trying to grow. and I'm growing outside in the back yard...Thanks in Advance

By R D P on 10 May 2015

I start indoors in jiffy pots during april through early june and when four true leaves appear move them out side I get enormous plants and bud using horse manure,compost tea,worm castings and a little blood and bone meal also plenty of sun .Make sure your seeds are for outdoors and for tropical type of weather.also make sure if in pots there is good drainage,so when the rains start your plants wont drown.good luck

By Jennifer ILGM on 11 May 2015

Thanks for all your tips and sharing your experience Danielle!

By Diane on 30 April 2015

I had 90% germination of my seeds by putting them in warm water in shot glasses. Then I sat the glasses on top of my hot water heater in the closet -- in the dark. Within a few days some had roots growing.

By Jennifer ILGM on 1 May 2015

Great! Thanks for sharing your experience Diane!

By Nicolas on 6 May 2015

So Florida has perfect weather for growing. Especially now that it's raining so much in Miami, then pure sunshine, the vegetative states should be at soaring heights

By booder23 on 13 May 2015

I started with a bag of about 15-20 seeds I turned the dirt over 12"x12" in my backyard outside picked out all the grass and just drop all 15-20 seed and now I have abou1 5-20 planets come up like side by side is thay ok to leave them like that because thay planned in my backyard not in pots?

By latewood on 29 May 2015

You need to have them spaced at least 2-3' apart. If need be, gently dig them up individually, taking care as to not disturb the roots. Gently replant them at a decent spacing. 🙂

By John Cox on 14 May 2015

Thank you Robert for those seeds .We will do business this fall after I harvest my 4 different patches .Wish me luck and keep growing it green .

By nighthawk on 29 May 2015

I have not had the chance to read all of the bible yet, but 2 things I need to ask, you dont mention the double ended light style, or sulpher plasma, LED nor anything about the Blue spectrum and its importance and effect? can you help everyone with some feed back on this?

Also, when growing with hydroponics, should the nutrient strength be diluted as you mention for soil plants?

My questions are pertaining to hydro-P (AKA..hydroponics)


By latewood on 29 May 2015

It is definitely better to have a full spectrum of light. I use HPS bulbs with enhanced blue spectrum. The industry standard is the RYE Hortilux. Most growers use 1 or another due to budget limitations. Some use MH (blue) for Vegetative growth, and an HPS (red) for bloom. The warmer Redpectrum lamps allows the plant to think it is Autumn and it oils up and finishes.

By nighthawk on 29 May 2015

with so many choices of lighting to use, which would you suggest is the best? ie..
Metal Halide, HPS, T5, LED,Induction Lighting or Sulphur Plasma? I did find this website with a comparison of all these types of lights, and it seems to show sulfur being the best, if I understand it correctly. Dont know if Sulfur puts out a lot of heat though?
Robert, can you give us your professional opinion here? Thanks

By nighthawk on 29 May 2015

addition to my last message... this is what Hortilux claims..."HORTILUX BLUE is the closest match to natural sunlight of any light source available today" But, isn't Sulfur Plasma closer match to sunlight?

By Winter on 20 June 2015

What are the best seeds for central Minnesota?

By latewood on 24 June 2015

We do not use plasma lamps; So, it would be incecent of us to speculate on whether this new idea is better. I can say; I am a big fan of Switchable digital lamp systems. They are efficient, and they are lost cost.

Eye Hortilux is a fantastic brand. Many old school indoor growers love this lamp. The best way to find out if the expense and yield work for you. leasecome to our forum and join in on the conversation. Peace, lw

By roy on 29 June 2015

newby at growing, love all the qt. and ans. and advice. it is complicated when you have limited $ and room. 65 on fixed income. old vet. hippy. love my herb. keep it green. I want to grow one or two plants to see if I can do it right and don't know the minum to make it work. love some hinks!!!!!!!!!!

By Jimbob on 25 August 2015

Try YouTube videos..some are good, some not. Bare basic Lighting: standard cfl's with a 3 or 4 bulb bath light fixture with socket splitters. Can get 6 or 8 bulbs on one fixture, need the 6500k. I think the homedepot 27w have something like 1600 lumens each, with 8 bulbs you'll get 12800 lumens. Grow space: try rigid foam board, cheap, insulated, easy to cut and tape. Fertilizer: can get pricey. I believe something on this order will work well for 2 plants and hard to get any cheaper. Just my thoughts you'll need to see what works for you. Good Luck.

" If you water it too little"
A tip, most people over water.
It's easy to fix under watered, its hard to fix over-watered
A good way to learn to water any plant, is ti pick the plant and pot up before you water it when its dry. Then after a good watering, after its soaked in completly. Pick it up again. After a while you will get use to knowing when it needs to be watered from picking it up, and just sticking a finger into the dirt.
If you stick you finger in the soil a couple inches and it feels like wet beach sand, its way too wet.

By David1954 on 25 July 2015

Hi, Another great read full of the best tips. Many thanks.

By Mattman on 29 July 2015

I use the compressed peat pods ("Jiffy Pellets") for the initial planting of seed. They're so easy and convenient to move and keep moist. Once the seed pops up and white roots are just barely poking through the sides and/or bottom of the pod, I then transplant into a larger commercial peat pot about the size of a large drinking glass filled with good growing medium. After the young plants mature to a solid adult stage (say, about the 4th or 5th pair of true leaves with at least 3-5 blades each), I then transplant pot and all into their final grow pots, 7 gallon-sized Smart Pots. Two transplantings and the roots are never exposed: seed into pod, pod into peat pot, peat pot into Smart Pot. Easy. Works every time.

By Ghostwire on 1 September 2015

I used to used the paper towel method of germination, but now I put the seeds between brand new sponges that I've moistened with water. I then places my seedling sandwich into a sandwhich bag and put the whole thing in a warm, dark place. I've had seeds germinate in as little as two days this way, with a taproot that clearly sticks out from the seedbody. Just remember to use new sponges as old sponges may harbor bacteria and fungi that can be harmful to your seedlings.

May all of you forever have a bountiful harvest.

By Jennifer ILGM on 1 September 2015

Thanks Ghostwire, great tip!

By jay sliger on 24 October 2015

Hey, what a great idea, do you keep a eye on the temp?

By jay sliger on 24 October 2015

I really love all of your articles and all that i can find, i am also a member of your blog.
So anyway as far as germinating seeds...what i do is soak them for about 24 hours in water,then i put them in jiffy pots at roughly a 1/4 inch deep,no deeper thou because the results seem to fall tremendously. So used to not soak them prior to planting them but they seem to come up quicker and more healthy..
grow happy, jay 🙂

By latewood.ILGM on 27 October 2015

Always keep an eye on temps in the room, tent, closet or...ETC.

Always make sure if you are growing ina hydroponics system to keep your water temps below 70f, 21c

"Gold Leaf" by Robert Bergmann

By Martin on 11 December 2015

Hey Robert, Im plating outdoors but I germinate the seeds in a pot in my house and then transplant them. When would be the best moment to transplant?


By latewood.ILGM on 12 December 2015


You can transplant to outdoors whenever you determine the plant to be strong enough to hold up against the wind, and after it has developed a strong root zone.

By Layton on 13 January 2016

I plan on growing inside and transferring them to an outdoor place covered by trees and next to a river. I plan on using the peat pellets, but I won't be able to use any special lighting. Would it be best to go from the pellets to a bigger pot or just straight to where I plan on growing them? And what would be the best seed for growing in central Texas?

By latewood.ILGM on 14 January 2016

If you are going to start your seeds inside and plan to move the plants outside later; You really do need to pot them and allow them to become strong young plants before moving outdoors. I am not sold on the idea of growing them under a tree canopy. These plants need a minimum of 9 hours of direct Sunlight in order to thrive.

By latewood.ILGM on 14 January 2016

As far as to what strain would work best; I suggest that you find a strain in our seed shop that fits your needs. All will grow in Central Texas.

By Taylor on 15 January 2016

So I'm new to this and super stoked. I live in southern Texas near Laredo. There is also a lot of oil in my town so I was wondering if it was even possible to grow with these conditions?

By latewood.ILGM on 18 January 2016


I can only assume that you are asking about growing outside. I am sure that there is a window of grow season in Laredo. I cannot tell you anything about the soil there, but I would grow indoors where you can provide what the plant needs.

By M on 3 March 2016

First time grower, gotta say "THANK YOU " !!!!! All seeds arrived quickly and discreetly, I followed your germination recommendations and to say all 5 seeds germinated and are looking great for only 4 days in soil.Fingers crossed, and I'll keep you posted on my results of your special blend, Goldleaf***. ILGM IS NUMBER 1 in my book, enjoy.

Livin Hi in AR. USA delivered in 10 days Very impressive ! The Ozark Mts. of Arkansas makes for some Fine Livin ! I'm told, Hill Billies love it. Thanks for your contribution to my Happiness Thank You for a safe and expedient delivery.

By Scott breihof on 7 April 2016

I have grown a few plants over the past few years. All the same way in a greenhouse in soil. Never had a problem germinating until this year the difference is I ordered seeds from this company. I bought five seeds one in each pot. I produced absolutely nothing from any of the seeds. Contacted customer service and they were absolutely no help at all. So it cost me 90.00 and not one of these seeds produced anything. I will never order from this company again.

By Jon on 9 April 2016

Just like to say that I keep things simple. I bought 10 white willow seeds. Put them in between 2 wet paper towels, put on a baggie, and put them on top of my hot water heater. In 3 days they had a root of about1" and were ready to be put in a small pot with potting soil. I read from you Bible, great stuff!! Thanks! Jon

By Griz on 4 May 2016

I tried the small peat pods in the small plastic greenhouse. When I tried to pull the covering off the top gently the whole netting came off, and all I had was a pile of peat, in which I couldn't find the seed, so I just kind of piled it up in the greenhouse and am hoping the seed is at the right depth. My first effort was successful soaking 1 seed for 24 hrs, getting a tap root, placing in rock wool and having under constant light from 2 CFCs from Home Depot, 2 30" fluorescents, and spraying plant, and keeping soil moist with a Alaskan fish fert. mixture, recommended by pro growers out west. The plant is growing well, has a good strong stem, it's in an 8" pot and 6-7 " tall and 6-7 groups of 3-5 leaf stems. Seems to be growing more out than up...time to move to 5 gal. Bucket? My point is I prefer the rock wool cubes, and be careful with the small peat pods

Problem solved . I put enough Mir. Grow pot. Soil into a 3gal pot, created suitable space for the transplant, removed plant from 8" pot, roots growing well all around outer edge. I guess that may be why plant growing more out instead of growing up? Huh?

More likely the plant is genetically disposed to bushiness. INdica maybe...

Soak in water 24 hours, into the soil outdoors. Mist multiple times daily until healthy. GL and WW Sprouts appear in 2 to 5 days.

I soaked my ILGM seeds in water and they Popped within 24 hrs. Much better than the, paper towel method I"ve used in the past, Also am Now using MG potting soil for starting plants. Very easy Thanks

most of my seed didn't germinate, the ones that did died a few days later. i followed the steps provided, and even tried different methods. Had the least amount of luck with the strawberry kush, gold leaf, and super skunk. None of strawberry kush germinated at all. (bummer) gold leafs germinated but died a few days later. super skunk germinated, grew for a bit then halted growth completely. The super silver haze are the only ones that seem to be legit... kinda bummed out due to the expense of purchasing 4 strains and only one seems to be thriving.

My ex-hippie born&bred girlfriend used to pop the seed/s under her tongue and continue doing odd jobs for a half hour or so- to get them nicely warm, wet and ready for their germination bed.
Kinda sexy at the time!

Been soaking WW seed for 24 hours and it's still floating at the top is this a bum seed or will it sprout ?

By Roy ILGM on 8 December 2016

Hi Mike, we've seen seeds sprout after a week of soaking. I'm not saying this one will need that much time but give it a little more 🙂

By Michael Douglas on 28 December 2016

Hello there, I recently put a couple seeds down in Fox Farm soil. I am indoors , and the temp is controlled.
However, my seeds have been down longer than 7 days and they are under flouresents but no germination as of yet. What am I doing wrong ?

By Roy ILGM on 29 December 2016

Hi Michael, there are a multitide of factors at work here. Actually too much to answer here. Best go onto our support forum and have our experts take a look. Create a topic there and supply as much info as possible and someone will help you out soon

It is important to start your grow with good quality seeds, bad seeds won't get you a supergroup. I always order my seeds online, straight from Amsterdam. They have over 40 years of experience there and you notice it in their genetics. I can advise anyone looking for seeds to take a look at, they have a great product range.

Thank you ILGM and Robert, I look forward to receiving my first order with you. I live in the desert, outside of Las Vegas to be exact. I intend to germinate and get started indoors using sunlight and then transplant to much larger pots and grow outdoors. My question, is how much heat and sunlight is too much? I had originally planned on shading and controlling it some on a open but covered patio, which they still would receive much light mainly morning and later afternoon for direct, but avoid the severe direct mid day summer sun. Around hear in summer we hit normal heat around 105-110F sometimes higher. So giving the plants sun won't be an issue, I just don't want to burn them up as most things will by mid summer. Watering is not an issue which I have a auto drip and sprinkler system controlled and programmable. Growing season again not an issue it is about to begin planting time here in no more than a couple of weeks, our winter is over and it was a cold month. Thank you in advance, I look forward to receiving the order.

robert i have kept approximately 50-50 seeds for germination but my problem is that i might not have enough pots to grow one in each can i plant 6-7 plants in a 20 liter pot?

By dot on 19 February 2017

budget wise i have to come up with other ideas to germinate my seeds ,, so this is it and it works great ,,get 6 toilet tissuses, fold 2 times , wet tissuses , put seeds onto paper , put second tissuse folded , on top, then get 2 container lids and put all paper onto one lid and put sm water onto paper so its just wet , add 2nd lid for top, put these onto electric blanket,on 1, with cover over top of whole thing , makes a awesm hot house,, oh blanket wz still on bed , make sure u check they dont dry out , and water frequently. they cracked overnight, and i left them till 3rd day , and into soil,, 3 were done and 3 cracked it .. yay

By Robert on 30 March 2017

Paper towel method works best for me , I have 100% success rate , just did 5 white rhino and all seeds sprouted in 48 hours !!

By Bob the Builder on 15 April 2017

A real newbie here! Have my grow space together. Going to soak the seeds 24 hours +- Then plant in 4" peat pots I have Fox Farm's soil Ocean Forest potting soil. Am I missing anything?

By Roy on 22 April 2017

Having germination problems!! 72 degrees, is that air temp of the room OR the moist soil???

By latewood.ILGM on 25 April 2017


During the propagation of seeds, we all like a warm humid climate. High humidity is key. Warm beds. Perhaps you need a heating mat.

We would love to see you around the support forum to share your experience. 🙂 – I❤️GM

I don't grow outdoors anymore however when I did, I always planted at the correct phase of the moon and you'd be surprised by the difference it makes! I used to by a MoonChart every year but I'm sure Google would tell you the information. It's nothing new as a growing tip. My grandfather was a farmer and always planted at the correct moon phase.

By Christine on 3 May 2017

Hello, im a first time grower in southern california. I have my seeds in water right now and am planning on putting them in the starter pots as soon as they sprout. What are average results of growing the plants in pots on a patio??

What happens if the seed pod falls off while transferring from wet paper towel to soil? (transferred with tweezers and placed very smoothly)

By latewood.ILGM on 25 May 2017


As long as the sprout Cotyledon, was not damaged and you are referring to just the actual husk falling off, then you should not have any worry. – I❤️GM

By glo on 21 July 2017

Hi"I'm a first time grower. some of my seeds are 30 years old, sister had them in a sealed tin. do you think they are any good???

By Roy ILGM on 24 July 2017

Hi glo, 30 years is a long time! If stored cool and dry all that time they may still germinate. Only one way to find out 🙂

By Matthew on 28 July 2017

A bunch of them will be. Seeds live a long time in the wild and these were kept dark and dry. SOAK them in water until they sink or when you tap them they sink. Then I use paper towel method w/ great results. Just sprouted 9 seeds within 36 hours. First ones within 20 hours. If some don't sprout remove from water, I know it says up to 7 days but that is not proper as seeds can drown after 24 hours. DO NOT throw away or give up on slow starters. Take an exacto, steel wool, anything abrasive will do. Scruff up the hull (don't cut in) and soak again. More will sprout. I take remaining slow starters and repeat until all spout or becomes obvious it was DOA. I have had almost 100% success on "OLD" seeds.

By matthew on 28 July 2017

Live in small condo and need to use my kitchen for veg room. North facing double slider door. Can I run lights dark hours only? Or run lights 18 or 24. I am going to be using this space for clones, veg, mother(s), and re-veg heavy producers for future grows. I also have grown from old seeds a wonderful mystery strain. How do I find out what it is? Is it possible to produce seeds?

hi. new grower here and I have blueberry, pineapple haze, and strawberry kush germinated for 24 hours in wet napkin. got a tap root and put them in peat pellets. they are under a 6500k t5 grow light roughly 2" above the pellet. the strawberry has came up and the other two have root started but haven't popped outta dirt. it's been 5 days since I put them in the pellets. I keep dirt moist around outside and spray top once a day. the one that popped has two 1/4" true leaves and don't seem to be growing now. should I add a lil nutes? on the one or all three? if not how long should I wait to add nutrients to babies? thank you for the info in advance

By latewood_ILGM on 5 August 2017


Never add nutrients until you have at least 4-5 true sets of leaves which proves there is a root zone to take up nutrients. Be patient or you will kill your seedlings.

As far as sprouts not coming up; Many things could cause this. Mishandling the sprout, planting too deep, drowning sprout with too much water, etc, etc...

Try starting seeds directly into peat pellets after following proper prep for the pellets. 🙂

I germinate my seeds the same way I make alfalfa and wheat sprouts , in wide mouth mason jars using screened lids found at natural food stores. Also been having success using my cloner and rooting directly in a foam insert, spraying 1 minute on, 10 off.

By Kelly on 16 August 2017

What can I do to help seeds that pop just enough to show white, then stall out? Never had a problem before, but this batch of TrainWreck has done it 3 times now. According to Murphy's Law #420.7, if I just germinate all the remaining ones, hoping for at least one to flourish, they will all take off and I will have more than I can use. Prefer to do one or two at a time, but apparently TrainWreck doesn't like being the only one out there. My tapwater ph could be lower, @ 8ish. Maybe I will try some ph adjusted water. Thoughts?

By Mallory on 29 August 2017

Thanks as always for your excellent guides, Rob! I'm sprouting 5 plants in a dome at the moment, and they're growing fast! I've been trying to keep my humidity between 50-60%, is this ideal? My temperature has been pretty steady around 21-23 Celsius.

By Ray on 4 September 2017

should you add nutrients to the water when you first start to germinate the seeds in rockwool, or wait till they have some good root growth first?

By Tim potter on 21 November 2017

I'm just starting to germinate some seeds inrockwall .this guy says add low nutes I've always been told the seed has all it needs for at least the first few weeks from sprouting so I think it's wrong to give low nutes rhixtonic is ok to spray o 've there little plants it don't feed for at least a week

By bill on 17 January 2018

theyre plants.just chuck em in water and voila,germination
theres no rocket science involved. Less is always better. dont change more than 1 thing at any time to see whats working and whats not.
most folk crash the 1st couple attempts so dont be discouraged

By Tim on 22 January 2018

I am planning on germination in peat containers and then going to 30 gallon grow bags. Any suggestions on soil ix for the bag?

By latewood_ILGM on 22 January 2018

from starter to 30 gallons is not efficient. You are going to waste a lot of soil because the roots will go to the bottom and all the upper soil will be unused. you must transplant in stages. several stages if you want to end up in 30 gallon pots. Any professional nursery or potting mix with peat, perlite, vermiculite, fungi, and dolomitic lime will do.

Happy growing.
