Hi, Im trying to decide what type of light setup to have in my grow space. Im not going to be able to have any ventilation in there. Planning on doing about three plants. I've attached a pic of my grow space. Was hoping someone could suggest based on my pic where you might reccomend putting the lights and what type of lights, hps or fluros. I understand hps must be about a foot away from the plants? Could that prove a problem in the shorter height parts of my grow space? Or can you keep the plants short under hps or do they like to stretch? Thanks.
