In our previous post we showed you how to germinate cannabis seeds using wet paper towel method. That method is good, but not perfect. To transplant those sprouted seeds you would have to touch them directly, which is not good. Freshly germinated seeds are like babies, you wouldn’t want to touch fetus with your hands that have oils and dirt on them. Same goes for sprouted seeds. It has to be sterile, so you would want to make as less direct contact with it as possible.

Freshly sprouted cannabis plant

Lets talk how to germinate cannabis seeds using peat pellets. We highly recommend using this method over wet paper towel method as this one is safer can gives you a better success rate.

For this to work you will need peat pellets, you can find them in any gardening store or order them online. These pellets contain lots of nutrients for your freshly sprouted seeds. They come in small, dry, compressed pellets. Peat pellets are not very expensive and definitely worth the price. They look like this:

How to germinate cannabis seeds using peat pellets – process

Once you have the pellets it’s time to prepare them. Soak them with water, we suggest that you’d use distilled water as tap water contains a lot of stuff that is not very good for these fragile younglings. Leave them for about 10 minutes and they will expand.

After 10 minutes (+/-) they should look something like this —>
You can plant your seeds in them. Use a pen to make small holes in them, about 1/2 inch deep. Put your seed using pair of tweezers in that hole and cover it up. One pellet should hold one seed for best possible results.

When you plant seeds into wet pellets, they begin their life. You should see them sprouting in 2-7 days period. Throughout this time, keep the pellets moist and warm ( 20-25°C). If they dry out, that might be the end of it. If you get good quality seeds, there’s nearly 100% success rate that they will germinate.

How to germinate cannabis seeds using peat pellets – next step

So your seeds have sprouted after 2-7 days. What’s next ? When you seed that your seeds popped out, you need to put them under direct light, cause once they pop, they crave for that light. Will it be grow light or sunlight, that’s entirely up to you and your chosen growing method. You need to do one more thing – transplant them into pots. Don’t pull them out of the pellet, there’s a very good chance you will destroy the plant. Just bury plant with the whole pellet. Roots will eventually go straight through pellet.

Congratulations! You’ve germinated some seeds. Now let ’em babies grow.

Where to get good quality seeds?

We have been using the service of “I love growing marijuana“. They ship very good quality seeds , and if you buy 10 or more seeds they throw in 10 more free off charge. They ship seeds worldwide, but if you live in a country that don’t have marijuana legalized, be cautious, make sure no one finds out about it. Be smart, be safe.

Germination Guide

If you are starting with seeds, you’ll have to germinate them to get the grow started. In this chapter, you’ll learn all about the natural conditions that cannabis seeds germinate under and then we’ll show you a failsafe way to germinate your seeds.

This cannabis seedling emerges 3 days after planted directly in soil

What is germination?

A cannabis seed is just an embryonic plant enclosed in a protective shell and germination is the process of reactivation of metabolic machinery of the seed. The outer shell splits apart and the embryonic plant emerges as a seedling. For cannabis seeds, this process takes between 1 and 7 days.

What makes seeds germinate?

Cannabis seeds lie dormant until they meet the right conditions to begin germination. In tropical conditions, cannabis seeds germinate in the warm rains of early spring. The well-drained soil of the forest floor wouldn’t be waterlogged, but it wouldn’t dry out. The ideal temperatures would be between 70°F-80°F (21°C-26°C), with 60-80% relative humidity. These spring seasonal signals tell the embryonic plant contained in the seed that conditions are right to begin its life cycles. These are the same conditions you will emulate to germinate seeds.

What’s the easiest way germinate cannabis seeds?

Peat moss pellets are pucks of dried peat moss enclosed in a fine netting. As a mostly inert medium that retains water well, peat moss pellets do a great job of mimicking the natural conditions of spring jungle floor.

What you need

Peat moss pellets – Get them online or at local department/hardware stores – they are widely available.
Filtered water – You probably have this in your fridge. pH balance between 5.5 and 6.5.

Peat Moss pellets swell to 5x their normal volume when flooded with water

Step 1 – Flood the Peat Moss

Peat plugs come dried and compressed, so you need to flood them with water. Use some warm filtered water from your fridge, rainwater, or distilled water that’s pH balanced between 5.5 and 6.5. Add water until the plugs are saturated, then drain the excess water. The plugs will swell 4-5x their original volume.

Step 2 – Insert Seed

Most plugs or pellets have a small hole in the top. Insert the seed between 1/4-1/2″ (6-12MM) deep and lightly cover with an excess medium.
All emerging seedlings look identical, and most mature plants look very similar. If you start multiple strains at once, make sure to label them. Plastic plant labels can be fixed to peat moss plugs to identify the plant through its life – adding dates makes it a self-contained record.

Step 3 – Wait for it!

The next few days is mostly a waiting game. Put the pellets in a partially covered container to prevent drying out and follow these two simple rules:

DO keep the pellets warm and moist throughout germination, cannabis seeds germinate best in these conditions.
DO NOT flood or over-saturate the pellets after the initial flooding, since this will prevent the roots from getting enough oxygen. Too much water and the seedling will ‘damp out’ and fail.

One easy method to ensure that you get the right amount of water is to use a spray bottle to wet the outside edges. Another is to quickly dip the bottom of the pellets into the water; moisture will wick upwards to the rest of the pellets. Either method will encourage roots to grow outward.

Step 4 – Care for it!

As your young seedling emerges from the seed, you’ll notice that it has a set of ‘built-in’ leaves that don’t look a lot like pointy cannabis leaves. These are the cotyledons, and they are there to help the young seedling bootstrap the photosynthesis process. Young seedlings need light right away – but not too bright for the first few days

Keep the peat pellet moist until the seedling is ready to plant in a growing medium, but never saturate the pellet since that can drown the young plant. Add water from the bottom up by dipping the pellet quickly in water. This will promote rapid root growth as the roots will grow down after the water.

When is it time to plant the seedlings?
You’ll know when it’s time because roots will be bursting out of the bottom of the peat pellet. Plant the pellet in a solo cup sized container using a quality soil mix. Water without nutrients for the first few weeks.

Optimizations & Alternatives

Germination Heat Mats

Germination heat mats are just like heating pads, but they don’t get as hot and are water resistant. These are especially useful for germinating seeds in colder conditions.

Germination Enclosures

One of the best ways to simulate tropical climates is to use an enclosure to conserve moisture and heat. You can make your own from cheap plastic containers, or buy a special purpose kit made for peat pellets. Used along with a germination heat mat, you can easily set up a tropical jungle climate anywhere.

If you want professional results with no hassle and complete stealth, try a professional grow-box.

Can I germinate seeds in paper towels?

Yes, you can germinate marijuana seeds in moist paper towels. Just put a damp paper towel down on a plate or other container and spread the seeds around. Add another damp paper towel or fold over the existing towel to cover all the seeds. You will need to keep the paper towels damp at all times throughout the germination process – a spray bottle can really come in handy for that. Covering the seeds with another plate or plastic will prevent it from drying out too quickly, just make sure that there is still some airflow for when the seedling emerges.

After a few days, the seed will crack and the embryonic cannabis plant will start to emerge. Once you see a solid root begin to emerge, you will need to transplant it into your growing medium. While this approach might be slightly faster than the other methods we’ve shown here, we don’t use this method because of the risk to the plant and main root during transplanting.

Can I germinate seeds directly in the growing medium?

That’s how it works in nature and it’s easy to do. Use a solo cup sized container filled with soil or coco and place the seeds about 3/4 inch (~ 2cm) deep. Keep the medium moist but not wet until you see the seedlings emerge between 3 and seven days later. The reason we recommend peat moss over directly planting in soil is that it is easier to control moisture levels in peat plugs due to the texture and qualities of peat. Experienced growers often sew directly into the growing medium.

Many farmers use rock wool cubes for starting clones and germination, particularly hydroponic growers. While these work well and are economical, they come with drawbacks. We recommend that new growers begin with peat pellets.

How long does it take to germinate?

From the time that you place your seed into the germination medium, you should start to see the emerging seedling within 2-5 days. Cannabis seeds germinate faster when they are kept at the correct temperatures, between 70°F-80°F (21°C-26°C), with a 60-80% relative humidity. Cooler temperatures will slow the germination process or stop it altogether. Germination is usually complete, and the plant is a young seedling within seven days. If you warm the seedlings with a heat mat, they can emerge in as little as 24 hours.

Should I germinate with nutrients?

Germinating plants don’t need any nutrients; it can burn their new leaves and roots. That’s why it’s best to grow seeds in an inert medium, like peat moss pellets or a paper towel. Young seedlings don’t need nutrients until they are a few weeks old.

Do cannabis seeds need light to germinate?

Not really, but they need light within the first day or so of emerging from the seeds, so it’s a good idea to germinate with a light source. Light sources also help increase the temperature, helping the germination process. Sunlight, fluorescent or low powered LED grow lights are all great options.

What if the seed gets stuck on the seedling?

They usually loosen and come off after a day or two. If it doesn’t come off, you can try to separate them. The easiest method is to find the direction of the crack and use a pair of tweezers to ‘help’ the seed continue cracking. Be careful that you don’t clamp the seed down or you can clip the folded embryonic leaves.

Germinating help with peat pellets

I am practicing germinating with peat pellets with some cheap seeds before I start my autoflower.
I started by soaking the seeds for 5 hours.
I got the pellets nice and moist, popped the seeds in to the pellets about 4mm deep. I placed the pellets (3 count) on to a upside down clear bottom container (9″x13″) [and dome is 5 inches tall]) with the lid on a germinating heat mat on the ground in my bed room the dome is sealed with no ventilation, there is big windows in my room so they exposed to light duringday time.
I left them sit for 24 hrs, when I checked them, they was dry but the dome was moist.
What am I doing wrong? Is the dome to big for 3 peat pellets? Do I have to keep the dome in dark room? If so could just throw a bath towel over the dome to block light to keep it still in my room? Do I need the dome ventilated or sealed?

Thanks so kindly!

I hated jiffy pots the first time i used them, they dry quickly. Push the seeds deeper To prevent shellheads and set the peat pots in a shallow pool of water til they sprout.

Here is what I usually do.

Soak seeds in distilled water for 16-18 hrs. Then I take 4 sheets of paper towel and fold in half then half again so it’s like 4 sheets stacked. Take 2 dinner plates place the paper towel on one wet the paper tower and fold open and make sure there is no pooling water. Tilt the plate so any excess water runs off. Place the seeds on the open paper tower then fold over so seeds are covered with no air gaps. Place the 2nd plate face to face with the first. If using a heat mat put a tower over it and place the plates on it. Check every 12 hrs. When the tap roots are about 1/2″ soak the peat pellets and plant about 1/2-3/4″ deep tap root down. Make sure to close the hole after. Should sprout within a day or 2. If using a dome keep the vents open. Seedlings have roots unlike clones so personally unless it’s dry I would not use a dome. They won’t need any feed for the first week or so and need very little light at first.

Alternatively soak for 16-18 hrs then plant pointed side down in peat pellets.

The pellets should never be wet or dry. If you need to remoisten use a spray bottle and mist the sides until it’s moist.
