Can I use HPS during flowering and a six light t-5 setup for vegetative? or can i use HPS for the whole entire time? I am trying to spend as little as possible, and I was thinking of running a six light t-5 for veg and then a 600 mh. Will I get decent grow from MH too? I mean from my understanding, HPS and MH are different, and are for optimum grow. Can MH or HPS be used the whole way? thanks.
