Tom, I see more and more UVB lighting showing up in various lights,.. usually these are some sort of fluoro' bulbs, notorious for weak penetration,.. We know for a fact UVB exposure does increase THC content, but there's NO comparison to the Sun vs. a bulb,.. the skeptic in me says such UVB bulbs offer little help for this overall,. just those bud under most direct exposure,...
Mark and Tom, have you seen any credible info about how UVB affect CBD content, or may in fact, destroy it, unlike THC , which empirically seems to shield the sensitive DNA in forming seeds>
