NO reptile lights are rich in UVA. The reason why HIDs like MH and HPS have little UVB is that the manufacterers are required to have low UVB output.
UVB is DANGEROUS. With only a few watts you can get sunburn in minutes under one of those. Medical facilities use UVB for certain treatments. It mutates DNA, it causes skin cancer, it causes blindness.
Here's a link from reefermans board

ANd just a disclaimer, oldtimer, the guy talking about the UV on that link doesn't reccomend using them.
he says
"So IMO, again - if you want to do it right and saftely, do it outside. I answered the question of the what the right UVB lamp is, not because I would advise others to do it(as I wouldn't do it myself), but as a guide to show that it could be done if one was crazy enough to do it."
IMO start with good genetics, keep them healthy and your pot will be plenty potent. If you want more potency, smoke another joint, or make some bubble hash. Pot's been growing indoors just fine without UV supplement, I'd be willing to bet that most of the pot in Amsterdam coffee shops are grown mostly under 600watt HPS lights since these are the most popular lights over there due to efficiency.
Dropping humidity will cause them to frost up a bit more and you won't go blind doing it.
