i have a few plants and i'm not sure that they're doing so well. one of them is a month old, two three week olds, and three sproutlings. should my oldest one be flowering yet? at what age are they supposed to start flowering? i don't know where to find proper lighting, and i don't know how much i should be spending. i'm only planning on keeping the few that are the best, i'm not looking for a whole extensive operation to take place here. i'd like to know how much would it cost for just one or two lights? i've heard they can cost anywhere from $5 to $500 for these lights, but i don't know. can someone enlighten me, please?
