nothing wrong with those, when used correctly. (you mean zoomed reptivite, right?)
there are a lot of factors - what type of prey, gutloading, lighting...
Mostly crickets, hoppers and flies for the moment. Have some silkworms coming in next week. Reptisun 5.0 UVB Gut loading is also being worked on, as I have a cheap store bought gut load and occasional fresh veggies. Going to order some bug burger. I appreciate your help and blogs! Reading up on some today at work
