if your growing for a collective i guess that means you live somewhere that its legal to grow cannabis for medicinal use? that would help out with not being so suspicious. i wouldnt give up i tried a closet grow 2 yrs ago it didnt work out and i gave up myself now im back i went the right way about it actual lights and a grow tent, i had an issue with my heat aswell it was because i didnt have enough air from inside being pulled out, so i put a bigger exhuast fan in or i guess you could say the correct size fan lol, a cfm fan isnt enough to cool a 600 watt mh/hps in a 4x4x6.5 tent lol, but i am managing it now. and yes it does look that way, i had trouble setting up my one light and ducting i could not imagine trying to do 11 lights and exhuast!
