HI! I purchased a 14% HO T5 UVB by Arcadia and put at 20" high from the substrate, do I run it all day? My I have a hermanns btw and will probably get another one for my baby leopard. Another questions is if I need to get another light running for UVA or the arcadia one should be enough, it says on the box that about having 30% UVA. Thank you for all your answers. New tort parents here btw, just wanted to give the best for my torts.
