I got roots in four days flat with my rdwc contraption, put them in Sunday night, just checked them and they are rooted as of Thursday afternoon. Tap water at 5.5 pH and some Clonex gel on the cut ends, jam into the rockwool and forget about them for a while. I put bleach in the water if I see any bacterial growth, 6 drops per gallon. Conventional wisdom be damned, it works! Rockwool is too wet, they say, aerocloners rule, they say, plants won't root if they stay wet, they say. I'm glad I can afford to explore a bit and learn for myself. Aerocloners probably are the best, but this works too.
