lol, ah a class. I get 100 percent germination this way. I had lost some seeds before using the paper towel or just popping them into media. No paper towel is needed with the cup of water. Just dark. I, in fact use plain tapwater straight from the faucet. Not cold not hot. Then place them in the dark. Traditional knowledge says that when they sink they are ready to go into soil, rapid rooter, rockwool, etc, etc. However, I dont mess with that and simply wait until I thinj the taproot is out far enough for how I feel that day, lol. That simple.
Rapid rooters are a gift from god. Or whoever it is that makes them. Very nice. Google `em. Very cheap and very handy. A coco peat or something material that is meant for hydro or soil. I have used them succesfully 100 percent of the time for both. No lie. They are also the perfect cloning medium.
When a seed has the taproot I use tweezers and place it into a rapid rooter cube or cone. Then I take a little peice of anything handy and gently cover the whole in the rapid rooter cube. The seed needs darl to keep sprouting and take root. After a day or two tops the seed will be poking out. Then just let it go.
Here it gets tricky about half the time. Because the seed does not half to push thru dirt the shell is usually stuck so a little very very very areful nuding is sometimes needed or the plant will die in the shell. It is Very obvious when this happens and what needs to be done and is actually pretty fun to do. SO dont stress. Also I like to put a clear plastic cup over the rapid roooter or the patch of dirt I bury the germed seed to keep the humidity up.
Keep the rapid rooter soaked. Keep the dirt wet too. Whatever you use. Rapid rooters are impossible to overwater. If you sprout in dirt be careful and just wet the the toplaer so as the seed stays moist.
