flooding? as in flooding the bed so as to submerge the roots entirely? and then my next question - flooding every 3 hours during light cycle, is it the same in veg (18-6) and budding (12-12)? thanks for all the help! Also is it critical to have 2 hps or can it just be 1? atm i realli only have enuf space to experiment with 2 lights and i would prefer to use 1 of the lights to veg and 1 for budding that way i break down the cycle into a 2 cycle, less wait time =)
