if you have a small closet,,get a 430 watt son T agro hps,,when I say small,,I mean 2 feet by 4 feet by 7-8 high,,with full mylar,,and a lil venting,,you could have 2-3 four footers,,if your in a cupboard or something,,then your gonna get small yield anyway,,so the lighting you speak of would do for a smaller space,,good luck on your grow
Keep on Growin
