You have a very reasonable assumption. I guess when it comes down to is if you believe providing a wide spectrum of light through out the entire life cycle is more beneficial than tuning your lights to the life cycle. If money is an issue (which I totally can empathize) than I would suggest two red suns and one super actinic... there is some literature circulating that suggests UV light aides in increasing the amount of terpenes, essential oils, and capitated, trichomes. I do not have ANY empirical evidance to back that up. But I think of that as more of a Pascal's Wager
