Anyone switch from reptile bulbs to semileds uv?

Has anyone done this and felt there was a difference and if so what spectrums of leds did you go with? Rapidled sells uva boards and now pucks but neither include any uvb leds. Is only uva needed to affect trichome production and terpenes? I thought it was a mixture of both but not too much uvb because that could degrade thc and bud production.

Search posts by nachooo. He might have some info, as he seems pretty interested in trying various uv options.

Also have a look at this thread.

UVA seems to affect thc and terpenes but also work well for general plant health if you dont over do it.
+1 for checking out nachoos stuff. He uses both uva and uvb.
