I'm taking clones, and plan on planting them directly into the net pots filled with hydroton. Theres a thread on here showing how to correctly transplant them into the hydroton, its easy. As far as using the rockwool, most likely the same method except cover the rockwool up a bit with hydroton or whatever media you have. A very experienced grower convinced me to use a drip system over my ebb and flow. If i could remember why I'd share his reasoning on the matter but it might be worth while to research it. If you have ebb and flow you hardly need anything besides some drip line.
