During May - September I am able to keep my chams outside most of the time. I know there are different UVB needs. With Jackson's being different than the Veiled & Panther [two being similar]. What I'm wondering is how many ReptiSun 5.0's to use. I have two 48" T8 fixtures [5.0 (x2) & Daylight (x2)] on the 24x24x48 ReptiBreeze cages & 36" T5 HO [5.0 (x1) & Daylight (x1)] & regular T5 36" [5.0 (x1) & Daylight (x1)] on the 18x18x36 ReptiBreeze cages [covering 2 cages side by side]. I keep the Jax (T5) and the Blue Bar Panthers (T5 HO) [as they average 4 months old] in the 36" and the Veiled in 48". I'm worried about them not being able to regulate their D3 intake with too many 5.0's. [I had been keeping them all under 2 5.0's and 2 Daylight dome lamps per each cage, as of today] YES, there are dividers between each cage, so no one can each other, before you yell @ me. Thank you for any and all advice.
