I'm pretty new to cloning myself first off. Don't let the rockwool dry out, I'd give 30-60ml(maybe more, I use jiffy #7's, not cubes) water each day(to the cube, enough to keep it moist, not wet), and spray the clones twice a day (some people just spray the inside of the dome too, may work better for you), in a week of 18-24 hrs light they should have roots, again YMMV. Anyone feel free to correct me. :stoned:
