Reminds me of stuff I have seen in the 3D printing groups for controlled drying of 3D prints. With the plethora of sensors and cheap programmable controllers you could probably whip up a chamber that could control both heat and humidity without much trouble. A quick web search turned up this page: https://reprap.org/wiki/Heated_Build_Chamber https://reprap.org/wiki/Heated_Build_Chamber I'm sure with some more digging others already have designed chambers for controlling heat and humidity. Might be fun extension/dual use for 3D printing and crystal growing. Overlapping hobbies are the best!
