....I found out a long time ago that limitations were meant for those who lack imagination and the will to excel, that being said, I hope to prove you "misinformed" so to speak.
.......................I am aware of factors beyond lighting, which have a major impact on growth and flowering in general. I aim to hopefully eliminate my dependence on HID for hi yeild grows. Just the elimination of heating control systems alone could make it worth the effort. Not everyone out there is able to maintain HID type grow rooms, there are alot of people that wont even grow because of all of the factors that are involved, but I digress, and again have to point out that I am doing this to gain knowledge of a new and expanding "class" of growers that are not in this for the money, but need MMJ for use as a means of relief from ailments. It only makes sense to put my best effort into it.
.......stay tuned, you just may be gettin the lip balm out for this.........................
LOL, seriously though,...Personally, I think you're best bet, would be to go with large CFLs, in the 200+ watt range(actual watts) setup for a vertical grow. Flouros simply aren't that efficient(per watt), so you have your work cut out for you, to say the least, if you are to achieve 1 gram per watt. I'm not dissing your growing skills, I'm just saying that you'd be one of the few in the world, to have achieved this. If you manage to pull 2 grams per watt, you might just be the first, with CFLs.
