So I see a lot of people associating light with yield saying that a 600w HPS will normally put out about 1lb. Well I have a 400w MH/HPS should I be expecting a certain amount from that or is skys the limit? I'm only running the mh right now but will be switchin to 12/12 hps in about 3 days. do I need to? will I see a difference.
