wow nice work man i just finished reading both your 2000watt grow and this one i like what i see. im setting up a similar set up right now but with 70 plants in 4" rockwoll per 4x4 with an air cooled 1k, no c02 and my temps are 25c with no ac(gotta love the cold winters of canada). im also using a 4x4 tent. now my question for you is how high up do you have your tables from the ground my rez is 15.5 inches tall im thinking 2 feet up but that wouldnt leave much room for the light to move. but i guessing you probly dont have to move your light to much. im only doing 5 to 7 days veg when ever there 6-8" tall.
thanks for all the very useful info and keep up the good work
