Grow Room Issue's

Hay Everyone?

I just have a new boxed put together the size is 4Lx4Wx6H.

The problem i have is, i dont know what size my exhaust fan and carbon filter should be for a box that size and also how big and how many passive holes should i have?

Any help would be great.

Thanks Guys.

I've got about the same size restrictions myself. Used a 6" 445cfm inline fan and was able to mount it in my attic about 7' from the outlet of the tent. No noise ! and with a speed control in place i have full control of exhaust, & temp. Hope this helps

The first thing I can think of is what kind of light are you running? If you are running a 600 w light a 340 cu ft on a rotostat dial running whenever your lights are running will probably do unless the outside temp gets to hot.

Best rule of thumb is to double the size(area) of your passive intakes in relation to your exhaust. Fan size will depend on what your running for a light. I would say a 6 inch fan should work fine. Got any pics of your cabinet? I am looking for more tweaks on my design that is going to be a similar size box to yours.

The type of light i will be using will be a 600w MH/HPS Switchable ballast, but for veg im thinking of using a few CFL's, 10 plants i plan on doing..
