i am going to be setting up my first grow with a grow tent and a 400w HID for lighting. the space is 36" x 20" x 63" and was woundering what would be the best fan for cooling the light and providing for a carbon filter. i just dont want to have multiple fans running unless that turns out to be the more benificial way to have circulation. any help would be much appreciated. One other thing is im going to be doing organic so would pest still be a problem inside of my grow tent?
