I've got a couple ideas for ya, use high intensity led lights the more the merrier. If you are growing in pots, you may get a better yield for you have complete control of your watering cycle,nutrient content. Most folks kill plants with kindness. That's one thing I have learned in my 20+ years of growing, for medical needs. I am a believer in radio playing mellow music, and when your with your plants, talk to them, I know they aren't going to talk back, however there is something about soft talk, and mellow radio that helps plants grow, after the years I've grown alot, and always talk and have a radio going with mellow tapes or cd sets going.try it, you might be really surprised
