What size filter and fan

[Blowinsmoke77]

I have 105cf room, have an aircooled reflector for 600whps. Thinking of cooling it separately with no air from the room. If I use a separate fan and filter any recommendations on another fan and filter for exhaust? I can use passive intake or find a smaller intake fan

105 cubic feet? That's a pretty small room. Something like a 3x5 with a 7 foot ceiling? A small bathroom fan would work in there and a DIY filter. Seems like extra work to do when you can just pull room air through a filter, through the light and then out. Passive intakes are fine. The only possible advantage that I could see would be that you could maintain negative pressure in the room with yiur smaller fan thus eliminating any potential smell. Then again I have set up 3 speed fans that stay on low until the lights kick on then they go to high.

4.75x2.75x8 are the room dimensions, currently I'm going to mainline one plant, since that's all my other half will allow for now. I currently have a vtx 600 450cfm inline from a previous time. Also have an inline 6" reflector. I've thought of buying a speed controller for my fan and using it as exhaust and cooling the reflector

That's how most of the small rooms that I've seen are set up.

Sounds like a winner, 1 hole is easier to cut in the ceiling than multiple
