I was wondering if any of you have used hydroballs to help boost humidity levels in your redfoot enclosures? For the time being I am going to be housing mine in a 40 gallon reptile tank with a screen lid (until space/money allow me to build something larger and have a summer outdoor enclosure). I live in upstate NY, so during the cold months (esp. with my electric heat) humidity will be an issue.... I was thinking of putting a layer of hydroballs in water beneath the substrate, which I plan to use a mix of repti-bark and forest floor cypress bedding. I will have an undertank heater, which I was hoping would keep the water layer warm enough to boost the humidity level in the habitat. Thoughts on this??
