Hello, I need some help designing my ventilation... didnt do any last grow and feel the grow suffered because of this. Room is 8 x 8 x 8, I have 2 blockbuster 6" hoods, 600 hps running in each...temps in room are actually a bit cold, they are perfect when lights are on, at 75, but drop down to 55-58 with lights off... so heat actually isnt much of an issue right now... Basically want the venting for odor control and fresh air. Going to be using 2 passive intake holes near floor on same wall as the exhaust near the ceiling. Just not sure how to set the rest up, I attached some pics with options and wanted some opinions on which to do...thanks much! Which option looks better and what if any change(s) would you make to the design?
