not sure yet on ventilation fan, looking at a 2x120mm computer fans than push 70CFM and are very quiet (i have 8 in my pc and it peaks at 43-45 decibles). 1 or 2 other fans mounted on bottom of side pannel hooked to a variable speed controller to control intake and temp. no automatic h20 pumps bc of cost. using for personel consumption, max 2 plants, OG kush. and ventiliation will be ran into an active carbon filter ($200) with shelf life of 18-24 months. cloning will come later. whats your opinion on cloning a clone?
