starting cannabis seeds in soil indoors

But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.

Within a week or so you should see a seedling begin to grow from the soil.

Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.

Is a bagseed good or bad?

Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.

Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.

Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.

Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.

Monitor your soil every day and keep it moist. Within four to seven days, you should see tiny stems sprouting from the soil.

To germinate seeds indoors, use any of the methods described above. Within a few days, you’ll have popped seeds ready to transfer to a growing medium.

When a seed enters an environment with enough moisture, it will increase in size and slowly break out of its shell. A seedling or germ forms from which roots will emerge, helping the baby plant absorb nutrients from the soil. Seeds naturally develop roots facing down and stems stretching upward, allowing the young cannabis plant to simultaneously feed off light and earth.

The downside of water germination is that once they’ve popped, you’ll need to maneuver them into their growing medium manually. This is a delicate process, as germinating seeds are extra fragile, and any harm risks the development of your plants. Make sure to place the seed roots down in the soil when you transfer to a pot.

Now that you know how to plant cannabis seeds in four easy steps, you might still have some questions about the details. Here is a list of frequently asked questions to answer some you might have:

You can lightly pat the soil to ensure that the plant can absorb the moisture correctly. However, try not to press down on it firmly once it is covering the young seedling. If the soil becomes compact, the weed seed might have a hard time getting enough oxygen. Not to mention, there might be a higher chance of disease from poor drainage.

There are multiple things to avoid when you plant weed seeds. Common tips include not fertilizing or adding extra nutrients to the seedling. As mentioned before, the plants can be vulnerable to too high amounts of minerals.

What to Avoid When Planting Cannabis Seeds?

Some growers use the damp paper towel method for the germination process. Sometimes, the newly-formed root of the seed can get stuck to the paper towel. The first instinct is to pull it loose carefully, but the action could potentially damage the plant. Instead, spray it with some water to encourage the root to let go of the paper towel.

The dimple should be about a couple of centimeters deep. If you are using a pencil, an easy way to measure is by making the tiny hole erasure-deep. Like any plant, you do not want to plant the weed seed too far in the growing medium.

The final step of the planting stage is one of the quickest ones to do. All you need to do is cover the cannabis seed with a thin layer of soil. About a couple of millimeters should do the trick. The thin layer is enough to block out the grow lights or sun while giving the seedling room to grow.

The seed can easily break through the top of the soil without drying out. Again, placing a mark on the pencil can help you see when to stop pushing it down.
