Grow Chest + UV-B

Hi RUI,

So since my 400watt HPS wardrobe grow got canned (No available room)

I decided to do a CFL grow chest - dimensions around 80cm(L)x50-60cm(W)x60cm(H).
To still get an OK yield I was thinking around 3-4small SOG plants, with around 4-10 65watt 2700K and some 6500K to bush them out in the beginning. (Too bad I have to keep the CFL's really close)

I'll throw some UV-B emitters in there too on a pressure switch to turn them off when the lid is open. Does anyone have any experience with these lights?

How much exhaust would I need? I've still got my 400+ CFM fan sitting around but I was thinking of using this 100CFM fan to exhaust, I don't think it will be enough though. Especially for upto 600watts of CFL and a UVB light too. I might throw in another 150CFM fan later in the grow.

Here is the fan's specs http://www.onlinecomponents.com/etri-rosenberg_148ve-0281-030.html?p=11313616

I'll probably have a drip feeding system too, just to make sure I can use all of that space. (in a separate sidetable)

Cheers for reading, input would be great!
