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 Germinate Your Own Pot Seeds
We value your support now more than ever.
All year we’ve been covering the issues that matter most to you—the pandemic, the election, policing, housing, and more—and now our end of year membership campaign is here. Will you support our work to ensure we can bring you the same informative local reporting in 2021?
Hopefully all of you aspiring growers have been able to get your seeds so we can move to the next step: germination.
Take great care handling seed and seedling. Most flower and vegetable seeds are simply planted directly in the soil, but because of the value of cannabis seeds, germinating seeds prior to planting is encouraged. Growers can achieve a much higher survival rate by germinating in a non-soil medium and then transferring the seed to soil once the tap root has emerged from the seed.
Here is one of the simplest and most successful methods: Put a double layer of paper towels on a dinner plate, then thoroughly soak the towels with water and tilt the plate to drain off the excess. Place your seeds on top of the wet towels and cover with another double layer of soaked paper towels. Be sure excess water is drained off—you don’t want the seeds to be swimming.
Cover the plate with an upside-down plate or pot lid. A plastic bag or plastic wrap also works. Don’t make the seal tight—you want to leave some openings to allow air flow.

Keep the germinating seeds away from direct light. For best results, keep them at about 75 degrees Fahrenheit. A radiant heat source, like a heating pad, helps expedite the process. If you’re using a heating pad, be sure to keep the heat setting on low and place a folded hand towel between the heating pad and plate: Direct contact between the plate and heat source can cook your seeds.
Under the right conditions, seeds usually open in one to five days, so check them daily. Do not allow the towels to dry, and add water as needed to maintain moisture. Some seeds can take as long as 10 days to germinate, but if seeds have not opened within 10 days, they are not viable.
When the seeds open, the first thing to emerge is the root. Once the root sprouts it can grow quite fast.

When the root grows to a few millimeters in length, the seed is ready to be transferred to soil. Always take great care not to damage the tap root when handling. The best soil to use for a sprouting baby ganja plant is a “seed starter” or “seedling” mix. These are light neutral blends with very little fertilizer. Heavily fertilized soils will kill seedlings quickly, and cannabis seedlings prefer loose, aerated soil that their roots can easily penetrate. A bag of good starter soil is easily identifiable: When you pick it up, it should feel light and fluffy. Soils that are heavy and compact are not good for seedlings.
Now, on to potting (no pun intended). A healthy seedling will be ready for transplanting into larger container, with richer soil, in about a month. A 16- to 20-ounce container is ideal for a seedling’s first home (many growers use a Solo cup). The container must drain, so punch some holes if needed.
Fill your container with pre-moistened soil and create a hole about a half-inch deep for your seed. The tip of a pencil works well for making the right sized hole. The seed should be about a quarter-inch below the surface.
Place your germinated seed, root down, into the hole and cover lightly. Do not pack the soil on top of the seed; a light protective layer of soil is all that is needed.
Once they sprout in one to three days, new seedlings will need lots of light, and fluorescent grow light works best. Give your baby ganja plants 16 hours of light per day.
It’s very important to have a breeze on your plants immediately. A fan placed at the proper distance and speed should create a breeze just strong enough so your plant “dances,” but not so strong that it’s bent in one direction.
Without a breeze, indoor ganja plants won’t receive the stimulus needed to develop sturdy stems and branches, which the plant will need to bear the weight of big, sugary buds.
