couple of q's about the xxl budbox, (2.4m x 1.2m x 1.2m). Have got a 6 inch rvk fan with carbon filter for top of budbod and an oscillator but do i NEED an intake fan for the bottom or will sufficient fresh air be sucked in naturally from the bottom vent? Also hasanyone got one of these beauties? If so is it easy enough to set up a partition to seperate veg, (clones) from flower?
