Jared_Lstarted grow question 4 years ago So as of right now I have 1 400w mh/hps light in a 4x4x6.5 tent. I know for a FACT that I can have way more light inside this tent. But my question to you guys is what kind of light do you think I should put in with my hps? Would like to have around 1000w or equivalent in PAR
