How To Germinate Marijuana Seeds

How To Germinate Marijuana Seeds

Germination begins the life of your plant, so it is essential to understand precisely how to do it. There are many methods for germinating marijuana seeds – some more successful than others. This guide will discuss the many ways to germinate your seeds as well as some strategies for ensuring you get the best results possible.

It Starts with the Seed

It Starts with the SeedLike all plants, marijuana starts as a seed. What looks like a pebble is actually an entire plant conveniently stored with a few day’s supply of food to support itself. During germination, this food is converted into sugars that the plant uses to break through its shell and form its roots. From that point forward, the young seedling depends on its environment to provide the nutrients it will need to survive.

Germination brings a seed out of its slumber and triggers the growth process. A seed will begin germinating once it receives enough moisture. At that point, it will increase in size and break open its shell. A germ opening forms and a root will emerge, which will help the plant absorb nutrients from the earth. Nature and gravity ensure that the root grows downwards and the stem upward, creating a young seedling that can survive off light and earth.

Since all marijuana grows from a cannabis seed, many people want to know how to identify a healthy seed. Honestly, it is difficult to tell if a plant will be healthy based on its seed alone. There are, however some tell-tell signs. Generally speaking, a pale-green or white marijuana seed will not germinate. A dark seed, on the other hand, is always worth trying. If you are unable to use all of your seeds, store them in a cool, dark and dry place until you can. A refrigerator is ideal.

Planning for Germination

Seeds are designed to germinate, but they are more likely to do so if given the ideal environment. There are many methods of germination, but they will all require:

  • Moisture to help the seed expand and break through its shell
  • Minimal interference so that delicate structures aren’t accidentally broken
  • Temperatures that mimic springtime (between 20°-22° Celsius or 68°-72° Fahrenheit)

Planning for Germination

If you remember these three things, your germination attempts are more likely to be successful.

It should go without saying that successful germination is important. Your seed is the foundation for your plants – which is why many successful growers choose to start with high-quality seeds. You can also improve your germination attempts (and possibly speed up the process) by soaking your seeds in 1% hydrogen peroxide or a compost tea solution for 12 hours before using them. This process will kill any infectious agents.

3 Simple Ways to Germinate Your Seeds

The best germination method is the one that works for you, and if you are like me, you’re going to want something simple and natural. My favorite way to germinate seeds is a 24-water soak followed by soil germination, but something else may work better for you. Here are three of the easiest ways to germinate seeds.

Directly in the Soil
Directly in the Soil

Planting your seeds in the soil that you intend to grow in is the most common and often, most successful method of germinating marijuana seeds. This method is perfect for ensuring young seeds have minimal interference since the fragile root is protected by the soil. It’s also the most natural way for marijuana plants to grow.

When using soil, first make sure you use the right type. Use mildly fertilized potting soil or a seed starter. It should have a pH of approximately 6. This type of soil will have spores and mineral that help young marijuana plants thrive. Do not add nutrients – potting soil has enough nutrients for at least the first two weeks of the plant’s life. If you add any more nutrients, you risk killing your seedlings due to a nutrient overdose. Place your soil in a small pot.

To prepare the soil for your seed, push your finger into it to create a small hole that is up to 1.5cm (0.6 inches) deep. You can also use a pen or pencil. Place one seed into the prepared hole and cover it with soil. If you’ve already germinated, the seed will have a root - place the root facing downward. (More on that later) After you’ve covered your seed, do not mess with it. That includes pushing it down further – this will happen naturally as you water it.

Use a plant sprayer to moisten the soil and place the pots under a fluorescent lamp. Don’t use a windowsill, because the temperature is not stable enough for germination. The temperature of the soil should be 22° Celsius or 72° Fahrenheit which is easy to achieve with lighting.

Keep monitoring your soil to make sure it stays moist. Within a week (or as little as 4 days) you should start seeing stems emerge from the soil. You now have a seedling! Once your plants are 2 to 4 inches tall (5 to 10 centimeters), move your plants into a larger pot with the stems further in the ground. Your plant will now have many roots that will support it for the rest of its life.

In Water
In Water

As I mentioned above, germinating in water is my favorite way to start my seeds. It may seem like a bad idea, as there is more water and light than recommended when using this method, but it works! I’ve found that it is around 90% effective. The “trick” is not leaving the seeds in water too long. I tend to leave mine in water for around 24 hours, but you can leave them soaking for up to 7 days without too much of a worry.

Water germination is useful because it assures that there is the right amount of moisture to begin germinating. If done for just a short period, it can help crack open the shell, pre-spouting the plant right before your eyes. Water germination shortens the process by making it easier for the plant rather than having to push through soil.

To germinate with water, fill a glass with tap water and allow it to reach room temperature over a few hours. The temperature should be around 18° C or 65° F. Do not add nutrients. Drop 2-3 cannabis seeds into the water and watch for any changes. Refill the glass with fresh water every other day while maintaining its temperature.
After about 2 to 4 days the seeds should start to split. You can place your seeds in soil at any point, but once the roots are 3 to 5 mm (.1 to .2 inches) long, they must be moved.

As much as I prefer to germinate my seeds in water, it does have its downside. At some point, you will need to handle your seeds, and this is risky. Germinating seeds are delicate, and the roots are especially fragile. If you harm them in any way, your plant might not develop well. Be very careful when placing your sprouted seed into the soil, and if possible place the root facing down.

In between two cotton pads
In between two cotton pads

Another easy way of germinating your seeds is to use cotton pads or paper towels. This is a common way of doing it because the cotton pads or paper towels can keep the seeds moist and protected. While cotton pads (or balls) or the best for this method, cheap, non-porous paper towels will work as well. Just make sure they are plain single-ply paper towels – the cloth-like ones may cause your roots to grow into the towel.

To germinate using cotton pads, place a few seeds between two cotton pads and moisten with a plant sprayer. When using a paper towel, place the seeds in between two paper towels and store the towel-cushioned seeds in between two plates, under an upside-down bowl or in a plastic bag. Keep the temperature around 22° Celsius, or 72° Fahrenheit, and (once again) do not place the seeds on a windowsill. In about 2 to 5 days, the seeds will start to split open, and a tiny root should appear. Place them in the soil when they are 3-5 mm or 0.1- 0.2 inches long.

Like the water method, germinating this way has its risk. If you are not careful, you can damage fragile roots while transporting them to the soil. You can also tangle the root in the wet paper towel if you are not extremely careful. Use your fingers or tweezers to move delicate sprouts, and don’t allow the root to grow too long before moving it into the soil.

Other Germination Methods

Water, soil and cotton balls are the easiest ways to germinate your seeds, but they aren’t the only ways. You can also use starter cubes or plugs. Simply drop the seed in, add water, and wait for it to germinate. They aren’t always as successful, but they eliminate the risk of damaging your root when transporting a young sprout to its final growing home. Below are two types of starter materials that can safely germinate your seeds.

Rockwool Germination
Rockwool Germination

Rockwool provides the perfect environment for germinating seeds. It is a mineral wool that is made from volcanic rock and other materials (such as basalt and limestone). Rockwool is man-made by melting its ingredients into molten lava that is quickly spun into threads. These threads are then compacted, cured and cut.

Rockwool is an ideal growing environment, but it will need to be amended slightly for marijuana plants. First of all, you will need to add some fertilizer before you use it to start seeds. The TDS should be around 600ppm. You’ll also need to lower the pH since Rockwool has a pH of 7.0, which is too high for germination. To lower the pH, soak Rockwool plugs in water for at least a day. Since water has a pH of 5.5, this will bring down the pH.

It should also be noted that there are some serious drawbacks to using Rockwool. Because it does not occur naturally, it’s not the best for the environment. It’s also not the greatest for your health; wear gloves and cover your mouth and eyes when handling this stuff.

Because of the extra steps involved (such as adjusting the nutrients and pH) and handling issues, this method is not recommended for beginners, although it is not terribly difficult to do. You’ll need to purchase and TDS meters for the most successful germination, but outside of that, the material is very affordable and easy to find. Because it does not require soil, this method is ideal for those who plan to grow hydroponically.

Peat Pellets
Peat Pellets

Peat pellets are another way to germinate seeds without the risk of damaging young roots. Peat pellets are compressed peat, which is made of partially decomposed vegetable matter and is simply yummy for young plants. The pellet enlarges when you add water to it, forming a container of nutrient-dense soil alternative around germinating seeds.

Unlike Rockwool, peat is already optimized for cannabis germination. It has a pH of 5.5 and a TDS of 625, so you don’t have to worry about making any adjustments. The only preparation required is soaking the pellets in warm water. Once the roots become visible, (by popping out of the peat), simply move the entire pellet into soil, rockwool, or coco coir, where it will continue growing. This type of germination is not recommended for hydroponic setups.

Peat pellets have a good germination rate, are easy to use and are suitable for beginners. They are also ideal for cloning. I recommend the Jiffy brand of peat pellets which can be purchased on Amazon.

Germination Environment

In addition to the material used to germinate your seeds, the environment you provide will play a huge role as well. Your seeds will need the correct temperature and levels of moisture to sprout into a strong, healthy plant. Below are some tips for creating the perfect germination environment.


Watering is essential throughout the cannabis life cycle, and germination is no exception. Not enough water and your seeds do not germinate, too much and that root doesn’t survive. Excess water keeps oxygen from the roots and can attract mold, which is why you have to be very careful not to overdo it.

When germinating indoors using soil or another growing medium it is relatively easy to monitor the water levels. You should water your seed until you see water dripping out from below (and not more). Even though the seedling cannot absorb that much water, it will evaporate quite quickly, so you need to make sure there is always enough around. If you water it until it reaches this point, it should supply enough moisture for a few days.

Lighting and Temperature
Lighting and Temperature

Like water, lighting is essential to a cannabis plant. In a mature plant, light enables the plant to form sugars from carbon dioxide and water. The plant then uses those sugars to power its growth – something we humans call photosynthesis.

For a seed, lighting is important as well because it provides heat, which a seed needs to push open its shell and send its root into the earth. The best way to give your seeds the temperature it needs is with fluorescent lights. (T5 high output with a color temperature of 6500K). Fluorescent lights are ideal because they do not use too much power, and they don’t give off too much heat. You can place them as close to a young plant as you need, and although your seed doesn’t need it at this point, it will as soon as those first leaves start peeking out from the top of the soil.

Incandescent bulbs can also be used because they are great at generating heat. You can’t use them as grow lights, but for germination, they work just fine. You can also use a seedling heating pad (available at most gardening stores). These heat the seeds from the bottom instead of the top. They will not be enough once your plant has started growing, however.

Keep the temperature of the soil around 72 degrees. Seeds germinate best in warm, humid temperatures, similar to springtime. To create a humid environment, wrap plastic wrap around your pot, creating a biodome for your plants. Just remember to remove the plastic wrap the minute you see any sprouts emerge from the soil. If the soil, or water, or whatever you are growing in is hotter than 72 degrees Fahrenheit, move the lamp further away from the plant. Dry air won’t kill seedlings, but if you can reduce it, even better.

It’s best to germinate seeds indoors. This is because indoors it is much easier to maintain the correct temperature, water levels, and light exposure. Even if you plan to grow your plants outdoors, you do not want to try starting them outside (unless you absolutely need to). Outdoors you must worry about rain, clouds and plenty of other things that could keep your seeds from sprouting. You’ll also have to wait until the final frost has passed, meaning your growing season may be delayed compared to if you had started the seeds inside. Starting indoors give you a head start and your plants a better chance at survival.

outdoor germination

If you still plan to germinate outdoors, choose a location that will support the plant its entire life. You will not be moving the plant, so choose wisely. Plant seeds when corn is typically planted in your area. Dig 6x6x6 holes at least three feet apart and fill them with potting soil. This will give the seeds enough nutrients to start. Then, dig a small, quarter-inch deep hole into the potting soil and drop the seed in. Soak that soil with water, and water it again in a few days if the weather is warm enough. You can use row covers to protect your seeds and keep the area warm but be careful to not leave them on too long – young plants will need the light once they break through the soil.

There is, of course, a benefit to starting your seeds outdoors if you plan to grow outdoors. Your plant will have more time to adjust to its environment and will be less likely to suffer from shock when moved outdoors. So it might be worth it if you know what you are doing. Just remember to leave plenty of space for your plants (those little seeds can grow quite large), know the weather patterns in your environment, keep your eye out for animals that may eat your seeds and use potting soil to provide the right amount of nutrients.

Planting your Germinated Seeds

Planting your Germinated Seeds

Once your seeds have sprouted, they should be planted. If you’ve used a germination method that requires you to move your sprouts, do so carefully, as the taproot is very fragile. You do not want to touch it. If you touch it or break it, it may survive, but it will definitely stunt your plant’s growth.

When planting, drop the white root downward. It should be placed about half an inch to an inch in the growing medium (knuckle deep). The top of the seed should sit just below the surface. Cover lightly and allow about a week (10 days maximum) for the seedling to break through the soil. It may emerge the same day – but if it hasn’t peeked through by 10 days, it likely did not survive.

If your seed is accidentally planted upside down, do not worry. Nature has a way of working itself out. As long as there is enough room for the roots to grow down eventually, they will. Give it some time and let it do its thing!

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.

Thanks, this was very helpful.

By Erin on 7 August 2018

Please do yourself a favor. Buy clones to start. You're guaranteed to get a female plant, and just one male will ruin your whole harvest. I grew my first time with seeds. I didn't know how to tell the difference between the two, even though my brother in law explained to me what a make looked like, it's EXTREMELY difficult, especially your first time, to tell the difference. I germinated my seeds in a wet paper towel and it worked beautifully. I probably pruned and dried to early out of anticipation, but the males fertilized the females and I ended up with more seeds than weed. I'm trying to find some Massachusetts laws on cultivation if anyone can help me!!

By Peter on 30 January 2015

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 Deepsand on 21 September 2018

Peat pots have no nutritional value to provide the rapidly growing plant. I plant in the small jiffy pod and once the seedling has grown for a week or so I place the pod directly in the soil in a small pot with ocean forest soil and no fertilizer as the ocean forest has all the natural nutrients your plant needs for a few weeks and it wont burn it.

Hi Maz, Just email our customer service at [email protected] and they'll make sure you get it!!

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

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.

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.

By Jennifer ILGM on 4 March 2016

Thank you M! We look forward to your updates, If you have any questions let us know.

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

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

By Griz on 4 May 2016

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.

By FyshhTrap on 26 June 2016

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

By jason on 30 June 2016

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.

By Tim on 12 July 2016

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

By Happy Larry on 16 January 2017

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.

By Mark on 1 February 2017

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.

By Dylan Cletus on 4 February 2017

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

By Anna on 27 April 2017

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?

By matt on 28 July 2017

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. 🙂

By Mahlon on 16 August 2017

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.

By shawn on 27 August 2018

You are rite on the mark.I drop my seeds in water and when I see the tap root pop out I put it in the soil with a success rate of 100%.

By Markie on 5 September 2018

I am not optimistic about this attempt to be a grower again, I am out close to $200 over the last 2 or 3 month's, and it looks like all i have to show for it ? is 3 small seedlings that survived a germination attempt with 12 seed's. (not from ILGM) so I bought 20 or so seed's from ILGM, over a week ago I attempted to germ 10 out of the 20 that I purchased. all ten popped and exposed there tales within 2 daysl, then 1 out of the 10 sprouted and started to show some leaf, I so I put that one in a cup with perlite and cocoa, and put it under a small powered grow light, that was almost a week ago. the other 9 seed's I put into the little rockwell cube's where they are still and not showing any signs of life. and the one that did pop and show leaf? has done nothing but stay frozen like a statue since its transplant over a week ago. I afraid that I have lost all ten out of ten seeds., that's pretty sad. I want more seeds or my money back..

By latewood_ILGM on 24 September 2018

As long as you have your order number and contacts [email protected], you should get a response.

If all 10 seeds popped and only one grew; It is highly possible you have something going wrong. We have all of customers claim super high success rates during germination unless they are doing or applying something wrong.

Coco and perlite is a terrible medium for a sprouted seed. Use Pro Mix,r, or something without fertilizer. Coco causes PH problems. As far as seedling not growing. Seedlings must establish roots before you see top growth. Meanwhile it appears not to grow. Patience is key.

No nutrients or fertilizer should be used and water should be PH'd at 6.1-6.5

I suggest you join our polite and friendly support forum and allow us to help you figure out what you are ding wrong. No offense. It happens to everyone at 1st. 🙂

p.s. I start all mt ILGM seeds directly into rockwool. Soak the rockwool in warm water. Gently shake some excess water out...Gently!...Do no squish the cube. add seed into hole in cube and pull a little piece of the corner and light place it into the hole over seed. All my seeds pop in 2-3 days maximum using this tried and true method.

By latewood_ILGM on 12 September 2018

John Hayes,

If you have determined females and plan on moving plants to a dedicated location, do it now before there is any chance of contamination or pollination. Since you are sexing, I must assume you bought regilar seeds from somewhere. Perhaps feminized seeds would suit you better, if you do not plan to breed seeds. Happy growing 🙂
