I have tried to paper towel method myself quite a lot of times and it does work well most of the time.
To prevent this from happening, I highly recommend soaking your seeds in a weak bleach solution for 20-30 minutes.
Step 1: Soak your seeds for 30 mins in a weak bleach solution to kill of any bacteria and / or fungus
How much faster exactly is also dependent on the seed, but generally it will cut down germination by a few days.
After 1-2 days all you do is spray the surface of your soil/rapid rooter…that’s all your plants need in this stage if you didn’t skip step 4 (so don’t water your seeds in the next few days, only spray them).
With hydro it is essential that you prepare your rapid rooters / riot plugs by soaking them in water for 12 hours.
To employ water germination, fill a glass with tap water and let it sit until it reaches room temperature or around 65 degrees Fahrenheit. Add two to three plant seeds per cup and allow them to sit, watching for any changes. Change the water to fresh tap water every two days, making sure it stays at room temperature.
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.
To germinate seeds this way, lay one paper towel on top of a countertop, place a few seeds, and cover them with a second paper towel.
How to germinate seeds in water
First, make sure you use the correct type of soil, either gently fertilized potting soil or a seed starter with a pH level of approximately six (6). The soil contains the right acidity and enough nutrients to strengthen your young cannabis plants for the first two weeks. Be careful not to add more nutrients, or you risk overfeeding and killing your seeds.
While many plants can be germinated in the ground, cannabis seeds are fragile enough that you should germinate them before planting.
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.
Soil is an easy, more natural method with which to germinate your cannabis seeds because the soil protects the fragile roots from any interference. Photo by: Gina Coleman/Weedmaps
