im hydroton rocks and flood and drain tanks filled with pots, allthe way. the versatility allows for removal rotation of plants, and is very good comercial set up. controlls real easy,and makes massive crops!
root in hydro straight into the hydroton in a rain forest cloner, plant in pot and move to the grow room tanks, later remove in the same pots and take to the flower chamber! the water or solution in the large flood tanks is sprayed in under high presure, making a massive airation rate in the root tank, which always has 1 inch min in reserve to keep those roots healthy that are growing out of all the pots into the system under and around the pots,
