I run my 6 in a 4'x4' tent....with pretty decent light penetration still around the outside edges....40"x40" would be awesome use of the 600 with the outer edges not being much different than right under the bulb.Sweet, thanks!
Edit: Also....If you're serious about getting a tent I wouldn't waste money on the cheapo ebay tents...it's gonna leak light at the stitching and seams after a grow or two...especially if you run a negative pressure in the tent like I do....Look into GrowLab tents...the GL120 is what I use....got mine for like 240 or something like that.
