aw sorry bout the link thing i didnt know. im half way through makin a new vegative grow box and a flower box, the veg box is 2ft by 1 ft and 1.6 ft high. im thinkin of changing fans as im gettin a 200w cfl light in there and i was thinkin of getting 2x 140mm 800-1500rpm fans. i was thinkin if this wil be be plenty would it be ok for a flower box a little bigger, i havent thought of that just yet. And thanks for helpin me out. (y)
