OR I was thinking I could get a hood with glass and vent holes on each side. I run intake and exhaust for the light,Then I run the exhaust fan out of the top that would cool only grow cab and some of the light heat that would come off it,I then run an intake fan right above the 5 gallon buckets with a bucket of ice water next to it (Ghetto AC) & finally run a wall mounted oscillating fan in cab. So many choices,This is gonna def be fun! I'm not aiming high for yield either! All I'm aiming for is a total of 10 grams. Would it matter if the carbon filter was on the ground?
