theres a lot of places to get cheap 400w hps/mh lights. i got mine on ebay for about 120 and there are better ones for around that price or just a little more. plus three of those are going to bulky and harder to rig up in a closet. just wait untill you have the money for a real light, unless you can get these for free. but growing costs a good amount to do it right so untill you have the money just wait and save and youll like the end product better. if you skimp youll end up with fluffy buds or small buds or not very potent buds.
