So I wanted to buy a big grow tent big enough to fill a normal size room, I want to grow 25 plants (clones) I just had a few questions, I know when the plants are in the veg state a MH light would be better and when in the flowering state a HPS light would be best. Say I got the tent how many MH lights would it take to grow 25 plants in a tent that size? Also when the plants are done in the veg state how do I switch lights (from MH to HPS) do I just unplug all the lights and plug in the HPS lights? How many HPS lights would it take? (Let's say the HPS and MH lights are all 600W) or is there a way I can plug all the lights in at once but ony use the MH for the first month or so then flip a switch and turn on the HPS light? Thanx guys
