Germination itself is a crucial aspect of cannabis cultivation. The seed germination process is the foundation of every marijuana plant, and steps can be taken to boost successful popping. For example, some cultivators improve germination attempts by soaking seeds in 1% hydrogen peroxide or a compost tea for 12 hours beforehand to kill any dangerous pests.

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

When the seedling stems reach two to four inches in height, it’s time to transplant your cannabis into larger pots with more room for roots to spread down and out. After you’ve done this, you’ve successfully germinated your cannabis seeds into proper, young plants.

Germination is the first stage of the cannabis growth cycle : the process that brings a cannabis seed out of its hibernation period and starts the cannabis growth process. After all, seeds in a bag don’t spontaneously start developing roots. Also known as “popping” seeds, seed germination begins when a seed receives environmental cues letting it know the setting is perfect to start growth.

Use a spray bottle to moisten the paper towels and then store the cushioned seeds between two plates, under a face-down bowl, or gently place them in a plastic bag. Maintain a temperature of about 72 degrees Fahrenheit, keeping the paper towel wrapped seeds in the dark and away from a windowsill. In two to five days, the seeds will pop inside the paper towel sandwich and emit tiny roots, ready to plant when they reach about five millimeters in length.

If the seedling leaves aren’t opening up because they’re stuck inside the seed membrane, wet the membrane and give it a few minutes soften up. Then use tweezers to gently remove the membrane. In some cases, it’s easier to stick the tweezers inside and pry the leaves apart just like with a shell.

Seedling Tray to hold Rapid Rooters

9.) You Have Seedlings!

At this point, the seedlings are ready to be put under a gentle light. A sunny window works well, though your regular vegetative grow light should be fine as long as you keep it twice the normal distance away. Avoid touching the seedlings if possible. This is when they’re most vulnerable.

If there’s a short root or seedling hasn’t germinated yet, put the paper towel back and gave the seedling one more day. Seedlings grow faster if they have a bit more root before being planted.

Rapid Rooters (note: extra Rapid Rooters can be stored in a cool place for future grows)

The leaves should appear above the Rapid Rooters within a day or two.
