Hey! Im working on setting up a similar idea to a computer grow box. Sadly though, i cant seem to find a way to wire the 3 12V fans i want in order to keep the environment perfect. I tried doing it through a powerpack (from the computer i ripped the fans from) but i get the feeling that i should have left the switch on to make sure everything was a complete circuit, though i chopped it off hehe. Also i am going to put one of those automatic air freshners that squirt out some scented crap, but this time fill it with water to control humidity. This will be wired to the bulb probably after i have the fans sorted. It'd also be great if you have any advice on optimising time for harvest, i'm willing to make yield sacrifices. ANY ADVICE? Thanks, Aaron
