This soil germination method is a low risk, easy method that that take up to 3-10 days. Read our guide to learn how to germinate seeds in soil.

How Deep to Plant Marijuana Seeds

There are plenty of suggestions and advice out there on how deep to plant marijuana seeds ? How deep should it really be, anyway? Well, professional marijuana growing has observed that the best depth of the dimple to make in the soil or the growing medium is about 1/2 to 3/4 inch and no deeper. One way growers do it is by marking the side of the pot to ensure they don’t go too deep and use the blunt side of a pencil or a pen to poke a hole in the growing medium.

Well, the idea is to position the seed shallow enough so it will not have a hard time sprouting while ensuring that it has still space to grow roots before it would need to totally support its full weight, this way the seedling will have time to develop support from its roots while in its early days. On the other hand, going too deep may restrict one element that is really required for the seed to germinate and grow. Only experience will give you a personal preference, but learning the basics of cannabis seed germination will lead to a successful grow. You will understand later as you read through this article.

How to plant marijuana seeds directly in Soil

1.Germinate your Cannabis seeds

There are 2 common and popular methods for this one and they are the Wet paper towel method and germinating directly in the soil. If you wish to do the latter and opt to go direct, it is recommended to soak your seeds in lukewarm distilled water for no more than 24 hours.

You will notice around the 12th hour that some seeds will sink to the bottom and together with those that will sprout a tiny taproot will be your most viable seeds in that batch. The idea is to fully saturate the seed with water which in turn will trigger the seeds to sprout.

2. Prepare your Pot where to Plant/Transplant your Cannabis Seeds

Fill 2-inch garden pots with your preferred growing medium or potting soil mix. At this point, use a pot that is small enough just to house the seeds, using smaller containers to start is always recommendable. Use potting soil or soilless mix that is loose and airy. They should be most to the touch. Make sure not to overfill your pots.

Alternative option – You can use starter cubes at this step and they are quite inexpensive and simple to use. This option has proven to be very effective when sprouting cannabis seedlings.

3. Make a Hole

Position your seed hole in the middle of the planting surface of your pot, aim around 1/2 inch deep and make sure not to go over 3/4 of an inch.

Tip! – You can use a pencil or a pen to poke a hole for the seeds to lay in and remember not to poke too shallow or too deep as this is crucial in this process.

Premise – Planting too shallow will not allow the plant to develop its roots while planting too deep will make it more difficult for the sprout to push through.

4. Planting/Transplanting your Cannabis Seeds

This step is fairly simple but there should be some things that we have to do correctly.

When dropping your seeds in the hole that you have made on your planting medium, make sure that the taproot is facing downwards or towards the ground.

5. Cover your seeds

Once your seed is well-positioned in the hole, gently push the growing medium over the seed and pat softly.

Tip! – Do not press too hard on the soil as this will disturb its growth.

Alternative Option Tip! – If you are using cubes, just gently pinch the hole shut and do not press on the cube.

The Bottom Line

When you are planning on starting your marijuana plants from seeds, a particularly “good start” will have a very crucial and influential role in the plant’s overall outcome. So, it is important not to over complicate it and let the plant do its thing. What is important on the other hand is us, the grower, must be always prepared to make sure that we can also provide the best environment for our beloved sensimilla.

Grow strong marijuana plants ready to transplant

All cannabis plants start as seeds, and they all require water to germinate properly. Each seed contains a full, little plant that has a root, stem and a couple of leaves. But you might want to know – how deep to plant marijuana seeds and how to grow strong marijuana plants ready for transplant?

How to grow strong marijuana plants

There are enough nutrients in the seed for it to survive the first portion of its life. During germination, these vital nutrients (proteins, carbs, etc.) are transformed into glucose, which all plants need for growth.

Soaking seeds

1. Let the seeds soak in water that is 65°F (18°C) until they split open and roots appear.

When seeds achieve a nice moistness level, they will enlarge and split open. A single root will grow downward with gravity out of that split. The root will always grow down no matter what and the stem will always grow up.

Placing your seeds in water ensures that they have achieved the proper moisture level for the process of germination to begin. The seeds will not take on excess water and drown until about 2 weeks after they have cracked open (you will have already transplanted them into soil by then).

When you fill your glass with water, simply put it in the living room so that it shifts to the temperature of the environment. Tap water is fine, but don’t give the seeds any extra nutrients because they already have everything they need. The seeds will crack open in between 2 and 7 days. Make sure to replenish the water in the glass every other day. Start transplanting when the roots reach 0.1 to 0.2 inches (3 to 5 mm) in length.

Planting

2. Place your seeds in a ½-inch hole in small pots with seedling soil
The nutrient level of the seeds is already adequate, so you should use a soil with fewer nutrients to start. Soil made specifically for seedlings and clones that has low quantities of nutrients is ideal. Plants are very susceptible to nutrient burn at this stage if you give them too many nutrients.

The pots should be filled halfway with the seedling soil. To make the half-inch hole, use your finger tip or a pen. Each seed should have its own pot. Since the roots will always grow down, you don’t have to worry how you place the seeds in the soil.

Place the seed in the hole, and cover it up with the soil. When you spray the soil with water, it will tamp down on its own. Avoid pressing the soil. The germination process will continue until the plant starts to surface within a week. The taproot will produce other root offshoots so that the system is strong.

Watering

3. Use a plant sprayer to moisten the soil
Water is responsible for both life and germination, making it the most vital component early on. It is extremely important that you give the plants plenty of water and keep the soil moistened.

Plants that don’t receive enough water will compensate by not growing to full capacity. This is largely to increase the plants’ chances of survival. Of course, too much water can cause the plants to lose out on valuable oxygen. Leaves will start to wither and the marijuana plant and growth medium will become more susceptible to diseases and bacteria.

Tap water is fine, but don’t give the seeds any extra nutrients because they already have everything they need. The seeds will crack open in between 2 and 7 days.

Soil Germination Method in 8 steps

Amongst the best ways to germinate cannabis seeds, this soil germination method is a low risk, easy method that explains how to germinate your seeds in soil. Germination can take 3-10 days, depending on environmental conditions and variety

Never use soil from your backyard! It can contain pests and moulds that will damage or destroy your seeds, seedlings or plants.

How to germinate seeds in soil

Read here which 8 steps you have to take for this soil germination method.

Step 1: Prepare your soil

Prepare your pots with clean fresh soil. It is often easy to use small pots for this, and transport them to a larger container later.

Step 2: Watering the soil

Make sure your soil is wet, but do not soak it. It needs to be damp but not soaked, otherwise you risk your seeds to rot. In most countries, normal tap water is clean enough to use. Do not add any additives to the water.

Step 3: Placing the seed inside the soil

Make a small dimple in the soil and place the seed 3-5mm deep inside the soil. Don’t bury your seed too deep! When you put your seed too deep inside the soil, it will struggle to reach the surface, and have a high risk of dying before it does.

Step 4: Cover the seed and press gently

Cover the seed with soil and press the soil gently.

Step 5: Cover the pots with kitchen foil

Cover your pot(s) with kitchen foil or microwave foil (with the small holes). The foil will act like a small greenhouse, keeping the inside of your pot warm and moist. Perfect for germination.

Step 6: Poke some holes

When you use normal kitchen foil, poke some holes through the foil. This will avoid the risk of overheating and let air flow true.

Place your setup in a room with stable temperature. 20-25 degrees is ideal. We often advice your living room

Step 7: Wait for germination

All you have to do now is wait. In our experience it often takes about 4-5 days for your seedlings to show. But to calculate for differences in conditions and seeds, we say 3-10 days is a safe estimate. As soon as your seedling has sprouted (first leaves reach the surface) you can remove the foil.

Step 8: Take care of your seedlings

All 5 seeds germinated in 4 days within 24 hours of each other. You can now place them under a grow light, behind your window or outside (during spring / summer of course).

WARNING! Do not place this germination setup outside in direct sunlight, especially during summer. Day and night temperatures vary too much and sunlight will cause the temperature inside your soil to rise to a point where your seed will be damaged or killed by the heat.

buongiorno dutch passion ho seguito il vostro tutorial e dopo 4 giorni la germinazione è avvenuta.una domanda vorrei fare,devo aspettare che si aprono i cotiledoni prima di rimuovere la pellicola o posso mettere il vas gia al sole anche se non sono aperti i cotiledoni. grazie e buona domenica

tutto ok germinazione perfeta.

When a seedling is in its first days its best to not place it in direct sunlight. This can be too much for a little seedling. When the seedling starts growing a little bit you can place it in direct sunlight

ok perfect I do this because I saw that it is the best method.I had put it in direct sunlight and it was dying, I managed to save it in time.I have one in germination and I will apply your advice.thank you very much Joe

Once the stem has come through the soil how long till you put it on a larger pot and up the tempreture

It depends a little bit on the pot size you started with.
Additionally, if you grow an autoflower its best to germinate them in the pot they will also flower in. They don’t like to be transplanted a lot.
If you grow feminised seeds than you can put them in a larger pot after 3/4 weeks.

Greetings,
Joe

Sweet thank you ,

Hi, Joe answering?? I did an error putting seeds in soil not enough wet and under lamp … I choose Orange punch feminized and autoflowering…Is a good choice for me ad a beginner or could you give me best options? (Medium-high THC and quantity of final result) I also need some good ideas about the soil to use and the power of led lamps (I’ve buyed 2x100watt multiple ranges led lamp for plant grown for about 60cm x 40cm for 4/6 seeds). I have to do another order and I’m trying to do all well. Waiting hopefully for your answer, my best regards, thanks. Heathcliff

Critical Orange Punch is a good strain to start your growing career. Please try to follow the germination steps from this blog and you should be fine Don’t start your light if the seeds have not germinated yet. For your soil I advice you to have a type of soil that has minimum nutrients because seedlings cannot handle too much nutrients, these should be added later :).
