How to properly plant weed seeds after germination?
In our previous blog about “Germinating weed seeds” you can read how to germinate marijuana seeds. Germinating is the preparation process to successfully grow a cannabis plant. It’s important to plant the seeds as soon as the seed has a sufficient root. Planting cannabis seeds is not complicated, but it does require some basic knowledge and skills. So how to plant weeds seeds? In this blog we tell you exactly how to do it!
Why germinate before planting?
Of course you can place a cannabis seed directly in the soil, but this has three disadvantages:
- The seed can become too moist, causing it to rot.
- The seed stays too dry so it can’t grow and because the seed is under the ground you can’t control it.
- You can’t determine the direction of the root. In short, our advice is to germinate before you start planting cannabis seeds.
When are you going to plant your weed seeds?
Once you have followed our advice, your seeds have germinated and you can start planting the cannabis seeds. Make sure the seeds have a root of at least 1.5 to a maximum of 2.5 centimetres. Are you planting the germinated cannabis seeds too early or too late? Then there is a chance that the plant will die at a young age. It is therefore important that you plant the germinated cannabis seeds as soon as the root is long enough.
Always plant indoors first
Good to know is that you first plant the cannabis seeds indoors, even if you will eventually grow them outdoors. The reason to let a young weed plant grow indoors first is because they are fragile in the beginning. A gust of wind can blow the plant over or be damaged by animals. Indoors you will have a safe environment where the young seedling can become strong enough before it is moved outside.
What do you need to plant cannabis seeds?
Fortunately, you do not need much to plant your germinated cannabis seeds. You often have a lot of stuff in the house already and otherwise you can buy it at any garden centre.
What do you need?
- Light-tight pot or cup from 1 to 2 litres
- Potting soil (light mix for cuttings and seedlings)
- Pen or pencil
- Germinated cannabis seeds
- Plant sprayer
Have you collected all the necessities? Then the real work starts: planting your cannabis seeds. Use the step-by-step plan below.
Planting cannabis seeds in 4 steps
In four simple steps you will learn how to successfully plant cannabis seeds. Whether you are advanced or a beginner, want to grow indoors or outdoors, the process is always the same.
How to plant weed seeds in a cup or pot?
Follow the steps below carefully and you’ll grow your own beautiful cannabis plant.
- Fill the pot or cup with potting soil
- Make a dimple in the earth
- Place the germinated seed in the dimple
- Cover the seed with a thin layer of earth
Step 1 – fill pot or cup with potting soil
Fill the cup or pot up to 1 cm below the edge with potting soil (light mix for cuttings or seedlings). Do not add extra nutrients. Seedlings get more than enough nutrients from the soil. Too much nutrient will have a negative effect.
Step 2 – make a small dimple
To plant your cannabis seeds, make a dimple in the potting soil. You can easily do this by inserting your pen or pencil into the soil. The dimple should be about 2 to 2.5 cm deep. If you mark this out on the side of your pencil, you can be sure that the depth is sufficient.
Step 3 – place the cannabis seed in the dimple
Use your fingers or tweezers to place the weed seed in the dimple. Do this carefully, because if you squeeze too hard you can damage the germinated seed. The root of the seed must point downwards (!).
Tip: Did you use damp kitchen paper when germinating and is the root of the seed attached to it? Do not pull it loose, but spray the seed again with water. You will see that the seed now easily lets go.
How deep do you plant the weed seed?
Make sure that when planting your cannabis seed, the root disappears as deep as possible into the hole. The skin of the seed should be at least 0.5 cm below the surface.
Step 4 – cover the seed with a thin layer of soil.
Carefully cover the seed with a thin layer of soil after putting the seeds in the dimple. Do not press the soil! A few millimetres of soil over the seed is more than enough. Spray the surface moist with the plant sprayer and place the cup or pot in the window sill or under light.
Your cannabis seeds have been planted. How to proceed?
You are already well on your way to growing your cannabis plant. But you might eventually want to let the cannabis plants continue to grow outside. As said before, you do the beginning of the growing process indoors which takes about two weeks. After two weeks the plant will be strong enough to repot to another place to continue growing. We will tell you how to do this in the blogs:

How to Pre-Sprout Seeds for Faster Germination
One of the most frustrating things about starting vegetables from seed is waiting for them to emerge from the soil. You can eliminate the wait time by pre-sprouting seeds. Presprouting seeds, is a method used to germinate seeds before they are planted into a growing medium.
I had pepper seeds that were several years old. I hated to throw the package away without checking to see if they were still good. I checked the viability of the seeds by doing a seed germination test.
About half the old seeds sprouted and the rest were duds. I planted the sprouted seeds and watched the seedlings carefully to see if they would grow. I didn’t expect much from them, but they did grow into healthy transplants that were eventually planted into the garden.
After experiencing how easy it was to see which seeds germinated, I decided to pre-sprout more of my indoor seedlings. I routinely pre-germinate tomatoes, peppers, eggplants, Swiss chard, melons, cucumber, squash, cilantro, spinach, and kale.
Benefits of Pre-Sprouting Seeds
A seed is triggered to sprout by warmth and moisture. Normally, you sow a seed into a growing medium, such as damp seed starting mix or peat pots. Then you cover the seed with soil, water, place in a warm spot, and wait for the seed to sprout and break through the soil surface.
Pre-sprouting lets you germinate the seeds first, and then you can place the sprouted seed with the root into a seedling container to grow. You can see the seed and don’t have to wonder if it is doing anything under the soil. Other advantages of pre-sprouting your seeds include:
- Saves money: Instead of throwing away older seed packages, you can pre-sprout to see if some of the old seeds are still viable.
- Conserves space: You don’t have to sow a whole tray of seeds hoping that at least half will germinate. Instead, you pre-sprout the seeds in a small container, and only plant the ones that germinate.
- Saves time waiting for seeds to sprout: Pre-sprouting accelerates germination because the seeds can be given ideal moisture, air, and temperature conditions indoors.
- Excludes the bad seeds: You only plant the seeds that geminate. Simply throw away the duds.
- Eliminates the need to thin out seedlings: With pre-sprouting, there is no need to toss three or four seeds into a pot and hope at least one will germinate only to have all four seeds sprout forcing your to eliminate the extras.

Materials needed to pre-sprout seeds:
- Containers or plastic bags: Any container or zipper bag will work. My favorites to use for pre-sprouting are the plastic see through mini muffin bakery containers or egg cartons. These are divided into small cells that are ideal for organizing and labeling individual seeds. The cover can be snapped closed to keep in moisture. Since the containers are clear, you can check on the seeds without opening the cover.
- Paper towels: A damp paper towel will help deliver consistent moisture to your seeds without drowning them. Too much moisture will cause your seeds to mold or rot.
- Water resistant labeling material: I cut strips of white duct tape.
- Water resistant marker: Sharpies work well and will not wash away if splashed with water.
- Spray bottle: A spray bottle filled with water is the easiest way to moisten the paper towels without soaking them.
- Seeds of choice: Larger seeds seem to work best. Try pre-germinating tomatoes, peppers, eggplants, Swiss chard, melons, cucumber, squash, cilantro, spinach, and cole crops.
- Warm and safe area: Moderate heat will help your seeds germinate quicker. Consider locating your containers in a warm area, such as near a heat source, or on top of the refrigerator. Around 70°F to 75°F is average for most seeds. Choose an area away from drafts and a place where the containers will not be knocked over or forgotten.
- Seedling containers: Have your seedling pots ready to plant once the seeds germinate. I like using soil blocks to grow seedlings. I make up a tray of soil blocks ahead of time so I am ready to transfer seeds when they sprout.
Directions for Pre-Sprouting Seeds
Step 1: Line your container with paper towels. I like several layers of paper towels, so I fold them in half and cut to fit. If you are using plastic bags, fold and cut your paper towels to fit.
Step 2: Label your containers. Use a water-resistant marker to label your containers or bags.
Step 3: Dampen your paper towels. Spray the paper towels with your spray bottle. You are aiming for the paper towels to be damp, not dripping. If you notice the water pooled in your container, dump out the extra.
Step 4: Add your seeds. Spread your seeds out on top of the damp paper towel. If you are using containers, simply close the cover. If you are using plastic bags, fold the paper towel over the seeds and place in the bag.
Step 5: Place in a warm area. Locate your seed containers in a warm area away from drafts. Also consider choosing an area where the container will not be knocked over or forgotten.
Step 6: Check seeds daily. Examine your seeds each day for germination and to make sure the towel stays damp. Spray the towel if needed.
Step 7: Transfer sprouted seeds to growing medium. Some seeds will sprout quicker than others. As soon as a seed shows tiny roots it is ready to plant. Carefully transfer your sprouted seed to your prepared seedling containers or soil blocks. Be very careful not to damage the root. If you do, the sprout will die. If the root has grown into the paper towel, snip around it and plant paper towel and all.
Place the sprouted seed on top of your growing medium and cover with dry seedling mix. Mist with your spray bottle and place under your growing lights.
Step 8: Keep your seedlings warm and moist. Use your spray bottle to keep the soil surface moist and continue caring for your seedlings as described from step 5 on in this article: 10 Steps to Starting Seedlings Indoors.
One of the most frustrating things about starting seeds is waiting for them to emerge from the soil. Pre-sprouting seeds germinates seeds before planting.
