im a little confused, why not just ask what the ideal light is for your own available area, thats what you want to know, right? If i vote for a 400 watt its totally irrelevant to you as a statistic as im only choosing it because i use it due to height restraints.
ya deff what he said I didn't know it was a grow tent. You would need a pretty big one for a thousand watter. If you don't mind me asking what are you planning on growing or which strain?
