Hash me about LEDs.
Easy to google and search for on youtube, this guy pulled 46 oz from one room, a 600w hid lamp, no reflector, and what looked like 50 plants. His 4 inch diameter plastic plumbing was set up in a downward spiral with holes for net pots drilled into the top. A water pump sent the water back up to the top and he treated the whole system as one plant... must have been the same strain. That guy is a genius.
