This is the second time I've mentioned Hydroponics on this forum... didnt get much responses the first time. But I think you guys will agree this Mini Greenhouse could work as a humidbox enclosure. It has vents on the top to control air flow thus regulating humidity. The price is awesome too! $25 with thermometer. This setup would work for a hatchling..but there was a 2x3? same design; heavy duty plastic. Let me know what you guys think.
