I want to start breeding Leopard geckos and i want to get a hovabator!! mainly because there the cheapest!! What temperature should they be set at. should i be misting the cantainers everyday? how does the hovabator heat itself....? is it like an oven with a S shaped coil...? and how do i adjust the temperature on the unit to what my hatchlings need.? i know its a lot but this would help a lot.
