Has anyone seen/used the Herpstat Humidity from Spyder Robotics?
This would be a great piece of equipment to hook up to a room humidifier to control the ambient humidity. Especially if using cages with lots of ventilation such as ARS, Freedom Breeder, or Vision racks. Have a ceiling fan and you're set.
Run the cages on that new Eco Zone thermostat, and everything's dialed in and state of the art!
With a room dedicated to boas, you couldn't get much better! Especially if you're someone working with a single locale exclusively. You could match the whole system to the wild.
