Thx for th advice, but i already did that. i have a a 120 mm pc fan exhust. instead of a 80 mm basic. it has the yellow thermo sencer wire thing. i cliped and taped that one off cuz i don't us it. i have it in the middle on top of top box. i also have 4 1inx3in holes for intake 2 on each box. i knew i needed High N for veg and high P for bloom. also im goin to start at 2 weeks at 1/4 strength so not to burn.
