okay, I was reading a care-sheet on day geckos, since I intend on getting one, and it said that some of the top breeders and hobbyists don't use UVB lighting, rather they use clacium supplement with D3 in it.... i've heard this before, and, don't get me wrong, i understand UVA is also good to have, but if UVB produces vitamins, the more important of which is d3, then couldn't you substitute costly UVB lights with affordable vitamin powder and seperate calcium powder that had D3 in it? I mean, I plan on using UV tubes anyway, but has anyone here and any succes with powder sans light?
