The environment in which seeds germinate also plays a role in the outcome. While there are several different germination methods, each requires proper moisture, minimal handling, and warm springtime temperatures between 68-72 degrees Fahrenheit.

Preparing to germinate cannabis seeds

Whether you’re planning an indoor cultivation or outdoor grow, it’s best to germinate your seeds indoors. It’s easier to maintain proper temperature, light exposure, and moisture inside, and you can protect your seeds from the elements. Indoor germination, whether using soil or paper towels, will ensure your cannabis seeds have the best chance for survival.
First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.
You can place the pot by the window sill or under a light. Wait a few days, and you will see the plant emerge from the soil.
Weed seeds can grow indoors or outside, but growers need to pay attention to the time of year before planting outdoors. Cold temperatures can kill a cannabis plant, so you will need to place it outside as soon as winter ends. The recommended period is between April and mid-May. Seedlings require the entire growth cycle before temperatures drop again.
When you place the germinated marijuana seed into the small dimple, make sure the root is facing downward. The root part needs to go deep into the hole as much as possible. The skin of the seed has to be at least .5 cm beneath the surface of the soil.
What to Avoid When Planting Cannabis Seeds?
After you are done filling the pot with soil, make a small hole for the germinated cannabis seed. Since the seedling is tiny, a clean pen or pencil can make the dimple the appropriate size. Place the writing tool on top of the soil and push it down to create the dimple. The depth of a hole matters for the growth of a weed seed.
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.
Some cannabis growers may fill the cup about halfway before planting the young seedling. Adding more can be beneficial for the root system. Continue putting soil in the pot until you reach about 1 cm below the edge of the container. You can press the growing medium down lightly, but do not compact it. When you have the amount you need, you can move to the next step.
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.
