Kingramo, the box idea sounds good i have that mini cardboard box on top of my set up just for now but i was thinking along those same lines i leave it ( box ) on top because i do have some air flow coming out the ac unit its not as stealthy as id like so thinking of relocating to attic but remember you need a compartment for your pumps, timers and fan exhausts/can filters etc.. to make it extra stealthy. Also i need the whole A/C unit because my summers reach 110 degrees in my garage so keep location in mind, on another note this is my first Hydroponic Grow and box so better installments waiting to come
