Hey MPers I got a question on ventalation.
My grow room is 4x4x8 and I'm using a 400w HPS light.
I have a 424cfm inline fan and a 250cfm duct fan.

I currently have the 250cfm hooked up to the hood and the 424 venting the room.
Is that fine or should I swap the two and have the 424 vent the hood?

Thanx

well i suppose the real question for you is, is your room cool enough with the 250cfm on the hood.....if not, switch it.

Thats the thing, its alright. It gets to about 79 lights on and just wondering if switching the two will help that.

Thanx

Use the big fan on the hood and the small for to vent the box. 79 is a little warm. The light produces the most heat, the more heat you remove from the light the cooler the box will be. 70 to 75 works best for me.
