GROW TIP: You don`t usually need 8" hood venting, you just need more AC, since unless the bulbs are allowed to reach high temperature they will not get to the maximum lumens output, and you`ll be cheating the light as if you had old bulbs, and your growth rate will suffer. Use 6" at most, and also put a speed controller in line to the fan pulling the air flow so you can dial it down to 1/2 speed, or dial it up if it`s too warm in the room.
