I really wish some university would go ahead and do the study on UVA So there can be conclusive evidence!
I think despite fighting the damn gnats, I had some extremely frosty girls in the 4x4 tent with the supplemental UVA. Not having to deal with gnats this time I might get even better results!......................edit.............and I'm only using them 12 hours mid cycle of the regular 18. The last run I ran on the same schedule as the main light. Actually, I think there's a bit of damage running it like that.
I thought Dr Bugsby had sort of come to a conclusion about UVA. But I guess it's not conclusive evidence.
