I don't need it. I have another 400 plus 216 watts of T5 florescent and the area is only 4' x 3'. I added a 750 w space heater to bring up the soil temps and I am returning the extra 400 I borrowed.

Purple doesn't impress me unless it's a killer purp strain. A purple pheno of most strains isn't anything special. I like the hashy or the gold tasting phenos, usually not purple.
