I spent way too much money. Thank goodness HPS AND MH lights and ballast were given to me, with replacement bulbs. Though I am sure one day I might want to bump the HPS from a 600W to a 1000W for that size of a tent and when if I do a larger crop. I would like to get a rotation going eventually, but it seems like I will have to veg in the walk-in closet, and flower in the tent. Dunno. Have you heard of a product called "Dense Buds?"
