Yo. I just had my first successful clones take root in a week in rockwool, and it was really easy. Just soak them in 5.5 pH water for a day. Then add about a third of the recommended dosage ( I used 3ml in my little container with 8 cubes in it ) of Clonex liquid to it. Stir it up a bit, pull them out, take the cuts, dip them in the water quickly after taking the cut, then put them into the cubes and into the dome. Spray ph'd water on them and the inside of the dome 3-4x a day to keep it moist.
I mean, I literally just topped my one-month-old from seed plants and got them to root doing it that way. I also plucked off the lower leaves with my bare fingers like 3 days into it, and pulled two out to check out the bottom of the stem - aka doing everything wrong, and yet it still worked fine.
