As a general rule, the seedling should be kept at 77˚F with a humidity of around 60%. Often, marijuana prefers a light cycle of 118-hours of white light per day once the leaves have emerged. You should be using a nitrogen-rich fertilizer at this point. Remember that all this is a rule of thumb. To get the best results, read up on the requirements of your particular strain.
There are a few ways to germinate a cannabis seed, but most people use the paper towel method. It’s super easy and won’t take long at all. Here’s what to do:
4. Flowering Stage: 6-8 Weeks (Most Important Stage!)
When the taproot has emerged, you can transfer the seeds to a growing medium. Depending on the strain, your growing experience, and your budget, you might want to use a different growing medium. Some people prefer a hydroponics setup, but first-time cultivators are likely to prefer soil.
If you want to try your hand at cannabis growing, check the laws in your state beforehand. Then, it’s vital to read up on all this related to cultivating cannabis so you can have a successful grow. In this article, we look at the seven steps of cannabis growing and harvesting to help you get the most out of your grow op.
2. Seedling Stage: 2-3 Weeks
Pick the fan leaves off the buds, and then trim off the sugar leaves. You can use these leaves for edibles, or you can throw them away. It’s also a good idea to collect the resin which accumulates on your gloves to use for dabs – it’s pretty potent stuff!
Marijuana light cycle: indoor—16 hours a day; outdoor—at least 6 hours of direct sunlight (“full sun”), plus several hours indirect sunlight
Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
Marijuana light cycle: 16 hours a day
As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.
Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.
Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.
Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.
Seedling stage length: 2-3 weeks
