i'd be leary of that tent. ask them does it contain PVC. and they don't accept returns. i've read at the most a 250 HPS will cover a 3' x 3'. i don't think the 250 HPS will push enough light to the edges. so either you can supplement the 250 or you can just put plants under the "solid" footprint of the light and keep them away from the edges.
