I don't trust hose clamps used on plastic couplings. My ex came along & over tightened the hose clamps on my ebb & flow system (back in the 80's) & caused a flood in the attic because he cracked the coupling. Straight up DWC is the most reliable type of hydro with the least amount of problems. One plant per bucket so if something goes wrong, you don't have issues with ALL the plants. Have you ever grown is soil? If you haven't & want to try something different, try organic potting mixes. Just one or 2 plants beside your hydro. As long as you don't over feed & cause nute burn, its basically more forgiving & CHEAPER.
-- BTW, where the heck you been? I thought we lost you!
