I have an inline scrubber, vented hood and a big green inline fan - what is the setup? Do i put the fan near the exhaust out and suck the air thru the scrubber, then thru the hood, and out?
if you do it that way then your sucking the hot air from your room and across your light not good, you can also push air through filters if thats an option
Are you going to run a dedicated intake to the hood?
Then its intake > hood >exhaust fan > out
If youre going to use the room air to cool the hood its:
Filter > hood > exhaust fan > out
Technically "scrubbing" refers to circulating air within a sealed room. The room air is sucked through a carbon filter and blown back out into the room.
