not sure as to the exact size that i am going to build the cab; but it probably be about 3 ft tall give or a take a bit, probably 2 1/5 feet wide and a depth of maybe 2 feet? again, these are just numbers im throwing around nothing exact. i had a question about ventilation though, got a diagram made up here to see if this would be a valid way of venting the grow, all input is welcome and much appreciated. im assuming a passive intake would be sufficient?
