I am under fluorescent lighting for three months. My acclimation is as much for wind exposure as sun. My area has some pretty decent wind well into June and a fan in the lighting area can't duplicate the back and forth snapping motion of severe outdoors wind. I view the acclimation as cheap insurance for my investment of time and money. No different than doing a credit default hedge on investments.As does mine. High quality or nothing. But the means to which I put it outside are hardly gonna determine final product near what dna and many other things would. Though I do have to re-cant. If ur under floros increasing sun exposure slowly day by day would be best. But anyone under hid, well my statement stands don't waste ur time
