I soak my seeds in a shot glass of tap water (my well water has a ph of 6.0 and only 105 ppm) for 24 hours. At the same time, I soak my rockwool cubes in tap water and 1 tsp of clonex liquid. After 24 hours I swirl the seed. If it sinks, I put it in the rockwool, if not, I push it down and check back a couple of hours later to make sure it stays down, then plant it. If the seed floats back up, I chuck it. Rockwool cubes go in a germination tray on a heat mat, with a dome. Usually, I have sprouts in 48 hours or less. Some strains have taken a little longer, like 3 or 4 days.
