UVb an experiment

But my favorite sativa dominate didn't seem to react at all. Plus, a mixed bag of results from various other strains of hybrids. Once I realized I was out of options to experiment further without having a baseline representative strain from each pheno, in my mind...it's a crap shoot for an average med gardener like me to go any further. Worth the toss of the dice, but no guarantee.
Close (under 1 foot) works best for those strains that react. But over time, would 6 inches be more of a benefit...? (more usable UV:M2) Would 2 feet be better...? (less UV:M2) Is fast and hard better, (6 inches, but only half-way through flowering) or is slow and steady (18 inches, but all through growth and flowering) the best...? Schedule for peak sunlight, or all day...?
And if the closer distance is better, is it because there is more of the "usable" UV bandwidth along the outer edges of the spectrums of light output by my particular bulb, and placing it closer increases this benefit, (inverse square law) or are the usable bands centered in my UV range, and my indica simply eats it up like candy...?
I also wonder what happens when you add UV in growth stage, but discontinue it in flower...? <doh> Sure wish I had more time to talk to the breeder when I last saw him. (the one that recommended I add the UV to my growth closet) His techniques are large-scale, (grows everything in both hydro and soil saying it provides different nuances to the flavors and effects) and I'm no threat to his cashflow, so am doubtful his insight was off. Nothing we talked about on other subjects was bogus, so am intrigued by his even mentioning it.
Ouch. My head hurts. <sigh>
