Sprouted up some seeds(2 of each)... Front to back... Haze Auto LSD Blue Venom Tangerine Dream AMS All sprouted and were 1" tall in less than 48 hours. Not all the seeds looked that great but sprouted just fine. I used 6.65ph 304ppm tap water with recommended amount of Clonex Seedlings nutrient and soaked the Root Riot cubes. Then I placed the seeds, 2 at a time, under my tongue, for approx. 5 minutes. Then sowed them into the cubes approx.1/4"-1/2" deep. The longest I've had it take for a seed to sprout, using this technique, was approx. less than 96hrs. In the near future, I will conduct a germination test with seeds using the mouth technique and seeds not using the mouth technique. Perhaps, it will show nothing, or perhaps it will show a trend of faster germ times.
