so with my last time around things were good. had a successful grow. but i hated having things out in the open. if a cop wanted to look in my closet, they would have seen some massive plants with huge buds and all my supplies ..etc. so now i want to do a stealth grow. something small with SCROG. to cool my closet last time i had to rig up a portable a/c unit. i did some fancy duct work and made it work. but now i wanna do some kind of cab/ box grow. is there any way to cool a 600W hps WITHOUT using a water cooled light. ive already got a couple of sweet inline fans that i used last time. what im thinking about doing is having 2 exhaust OUTS (with the inline fans) and 3 fresh air intakes. im not exactly sure what im gonna use as a box/cab, but im thinking about using a cheap gun safe. what you guys/gals think?
