im not finished yet, i need to cool my 250w Swtchable light w/ built in ballast. I have this fan or i can buy some pc fans? which would be better, i was gonna cut a whole in the back of the closet and put the (pic) fan right above the light what do you thnk
it would work well. if you put the fan at the top pushing air out of your grow room, you can put holes toward the bottom to create a passive air intake. theoretically, it will also help keep the smell in the box this way too, but everytime I have set up a box this way, it tends to help the smell, but not completely get rid of it.
