I like a lot of growers used to do the paper towel thing until I read the words of Mike at Mandala seeds. I quit doing the paper towel thing last year and have never looked back. If you think about it for a second in nature how many cannabis seeds in the wild happen to fall on wet paper towels and germinate. Most fall where they may and do just fine. Don't believe it take some old bag seed in the spring of the year and broadcast them along a ditch bank and see what happens without the paper towels.
I just germinated 15 Mental Floss, 5 Northern Lights and 5 Blueberry X Ak47 seeds this week in 16oz cups with potting soil and ph'd water. 100 percent success, no problem. BTW the Image Reaper is right on.
