Quick exhaust help please

[Type_S150]

I have 2 fans and want to know what the best way is to set up the exhaust. Should I do:

A. Charcoal filter> exhaust fan>air-cooled hood>exhaust fan>ducting out of room

B. Charcoal filter>exhaust fan>air-cooled hood>ducting out of room (then use the second fan I have to just suck out air by itself seperate from the filter/light)

C. What you think I should do

Thanks for the help.

dont use one fan to suck out of the room, it will defeat the purpose of having a filter

Sorry, Im a little confused (novice grower)- can you elaborate a little bit? Do you mean dont use 2 exhausts?

If you have one fan with carbon filter and one without, you might as well not have any since one of the fans will be exhausting unfiltered air.

I would pull air from outside the room to cool my light and then it wouldn't need a carbon filter. I would use the other fan with the carbon filter.

Fan 1: Ducting from outside room>air-cooled hood>exhaust fan>ducting out of room.

Fan 2: Ducting pulling air from floor level>charcoal filter>exhaust fan>ducting out of room.

Can you just use one fan? I am currently using a 6" fan on top of a charcoal filter ducting through the hoods and out of the room. I recently got some advise to vent air from outside, through my hoods and back out, and to use a fan on top of a charcoal filter to scrub the air. Does that sound correct. There are many ways to do it and I guess I get a little confused. Thanks

The way I am setting mine up is I have my two 600's above my table with my charcoal filter attached to the ceiling between them. I run a 6" duct off the filter through the first light, then the second light, then up through the ceiling into the attic. That way i can cool my fans and exhaust my room at the same time, and eliminating odor. I have my second inline fan pulling fresh air through a hepa filter from outside. That duct runs to the floor. Whatever you do make sure your exhaust starts at the ceiling because that is where the hot air sits.
