The positioning can help the top of the plant and its roots grow out correctly. The stem could bend and not develop properly, and the roots might sprout upward. The weed seedling might not turn into a healthy adult plant.
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.
Step 4 — Cover the Seed With a Thin Layer of Soil
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.
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.
Try not to cover the pots with plastic or create a humidity dome over them. Air needs to pass through easily, and a buildup of humidity may damage the plant. Besides avoiding the wrong soil, make sure it is not too wet or too dry. Whenever you water the seedling, make sure it does not have the wrong pH level.
The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.
Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).
CHOOSING YOUR GERMINATION METHOD
Before we jump straight into the germination methods, there are a couple of germination golden rules. For the best results, we recommend staying within these guidelines, no matter how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a sign that they need to do so.
Maintaining the ideal temperature (between 22–25°C/71–77°F) and moisture for germination is tricky. Leaving seeds out in the open environment or on a windowsill is far from ideal; a DIY climate-controlled cupboard would do a much better service. A warming mat is perfect for maintaining a constant temperature, but it doesn’t tackle the issue of moisture.
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
