Other than drying out over time, one disadvantage of the paper towel method is that there is a chance of hurting the taproot. Be careful when checking on the seeds, and do not move them too much.
Peat pellets, starter cubes, and seedling plugs are easy to use, which is beneficial for beginners. You do not have to worry about spending time for preparation. Another advantage is that you can transport the cubes with ease, especially if you use a tray.
Place the seed inside the hole and cover it up. Then, you can add some water. The packaging should have instructions on how much water to add. The weed seeds can take anywhere from two to five days to finish germinating.
Wet Paper Towels (recommended)
Now that you know how to germinate cannabis seeds, the next step is to plant the sprouted seedlings. You do not need much in terms of planting. For example, you will want a large enough pot and a plant sprayer. If you used incandescent bulbs to keep the seeds warm, switch them out for actual growing lights.
Some people use paper towels right after the water soaking method to get the remaining seeds to germinate. You can use paper towels from the start as well. The first step is to dampen the paper towel and put it on a plate. Place the seeds on it before folding the paper towel over.
The paper towel can dry out, so put a bowl or another plate on top to trap the moisture. Alternatively, you can spray the towel every five hours to keep it wet. The process can last one to four days, so check periodically to see if the taproot appeared. If you have older seeds in the paper towel, you may end up waiting longer. Afterward, you can place the young seedling into a growing medium.
At first, the seeds will float, but they will sink to the bottom after a few hours. Carefully push them down if they are still floating. You can leave the cup in a kitchen cabinet or dark area. Keep the glass there overnight or for 18 to 36 hours. Try not to leave them soaking for more than 36 hours. If there are any seeds that have not finished germinating, leave them in a moist place until they sprout.
Soaking seeds in water/wet paper towels is a method which can be used for old seeds (3+ years) that are drying up and losing germination power; and for pure land race equatorial strains such as from Africa. Both factors do not apply to our seeds. Fresh seeds have a healthy embryo whose cells are filled with water. But excess water causes the cells to bloat, depletes oxygen and leads to the tissue rotting away before the seed embryo can germinate. Old seeds have lost water in the cell tissue, the embryo starts to shrivel, which is why germination rates drop the older the seeds are. Therefore, old seeds (ie. 3+ years) can soak up more water before adverse conditions cause them to rot. This is one of the main reasons why various seed stock reacts differently to pre-germination methods. Some growers make the mistake of soaking our seeds in water for up to 1-2 days because it may have worked in the past with other seeds. This does not mean, however, that this method can be used for all seeds. In fact, old stock or equatorial cannabis seeds should only be soaked in water for a few hours at the most. Always consult the web site of a seed bank for specific advice and instructions on how to germinate their seeds.
Humidity domes are only required for rooting cuttings.
Germinating cannabis seeds is not difficult.
We provide the basic information and many hot tips on what is important to support you in having a successful start!
Cannabis is not an orchid or swamp plant! The seeds need a well aerated growing medium to germinate well. Seedlings also cannot tolerate high humidity and can easily be attacked by fungus such as fusarium and pythium. Only the soil or growing medium should be moist for optimal germination and seedling growth. Ambient humidity is best at or below 50%.
Due to our high standard of pollination, attentive grow methods, and the dedicated hand selection of seed stock for sales, our seeds are always perfectly matured and can be quite large. They also possess a particularly intact and hard seed hull. The robust genetics of our cannabis varieties, and our innovative Deluxe seed production methods, leads to the development of healthy and strong seeds with a good resistance against environmental factors. Due to the firm seed hull and large size some of our seeds may require a slightly longer germination time. Most seeds sprout in record time and others take a bit longer. Once the seedling grows through the substrate it will develop quickly and vigorously regardless of the germination time.
