The seeds should start sprouting in about two days, though older seeds can take up to a week to sprout. You can remove them from the water and place them in the soil at any point once they’ve sprouted. Once the roots are about five millimeters long, they need to be planted.
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.
You can also germinate your seeds by placing them in water. It’s slightly faster than the soil method, but you need to adjust your environmental factors accordingly. Remember, successfully germinating seeds requires a perfect balance of ideal growing conditions. When germinating in water, seeds need only 24-48 hours to pop their stems, though cultivators can keep them soaking for up to a week as needed. Water germination is faster because the seed gets all the moisture it needs immediately, and the shell softens and cracks more easily after soaking.
How to germinate seeds using paper towels
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 best germination method depends on the cultivator’s choice. Here are some of the most common ways to pop your cannabis seeds.
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.
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. Photo by: Gina Coleman/Weedmaps
Note: Move grow light down early if seedlings start getting tall with long stems. Tall, stretchy seedlings are telling you they want more light.
Sometimes leaves get stuck in the shell. Here’s what to do.
Create happy little seedlings in less than a week!
7.) Check on Seeds at Least Once a Day
I used to use my fingers to remove shells but it can be hard not to disturb the seedling. Then I learned that a pair of pointy tweezers can be inserted into the crack and allowed to gently open to pry the seed apart. Don’t tug or use any force whatsoever. Just gently and slowly release the leaves. The leaves may be stuck to the shell at first and it can take several seconds of gentle tugging for the leaves to slowly loosen and pull away from the shell. If you’re having trouble, add some water to the stuck part and wait a few minutes to help soften it up.
Did you know the first two round seedling leaves were already fully formed inside the shell? The germination process only releases them. New leaves are yellow at first but turn green once they start getting light.
At this point, you may see some seedling leaves have already broken free of their shells. That’s awesome. These seedlings often grow the fastest.
Seeds typically germinate in 1-3 days!
Keep it moist – Make sure that the cannabis seeds are kept moist but not soaking during the germination process. On average you should soak the seeds for 24 – 32 hours. They shouldn’t be left to soak longer than that. By keeping them wet and not moist you could actually drown your seeds.
Leave them alone – Make sure to not disturb your seeds while waiting for the taproot of the cannabis seeds to grow.
That small white tendril that breaks out of the seed when germinating cannabis seeds is your plants very first root. This root is also known as the taproot. This is the main root of the cannabis plant and every other root it produces will grow off the taproot.

Be gentle – Always be gentle with new seedlings. Do not touch the white taproot they produce. It is very fragile in the early stages of its life. Always be gentle with planted roots south africa.
Take the plate to the sink to drain out all the water around the paper towel. Tip it and make sure that all access water has been removed from the plate. You want the towel moist not soaking wet.
The taproot of the cannabis seeds will begin to grow longer. As it grows longer the seed will get pushed upwards. Eventually, the shell of the cannabis seeds will push up through the growing medium you have used. The first leaves are known as “cotyledons” and they will begin to appear soon.
