Hey guys, This is going to be by 1st grow and I've been reading up a bunch of stuff on this forum. I think the following will be my set up. 4x4x7 grow tent in my bedroom 600 watt hps/mh light set up 4 plants in hempy buckets carbon or charcoal filter exhaust The questions I have are the following: 1) Is the 4x4x7 tent enough room for 4 plants? 2) Is the 600 watt hps/mh light combo enough for the 4 plants? 3) How much wattage do they suggest per plant? 4) Will this set up spike my current electric bill? (I don't think it would) 5) Will I need to be concerned about humidity? 6) What type of seeds are good for a 1st grow?
