Choong,
Very interesting setup Choong, thanks for sharing. I was thinking of a similar setup by using water to chill the terrarium but from different perspective. Instead of using the "immerse" style, I was thinking of the "drip method". Chilled water will be channel and flow along the inner tank walls (like a wall of water) except for the front viewing side, then I'll put styrofoam or similar heat insulating material in between the inner tank and outer tank leaving only the front viewing part visible. I was considering this method because humidity can be kept at high level at all time. Then again, for intermediate/HL species, would high humidity level be essential for good growth? I got not idea since I've yet to keep any true HL only species.

What's your view on this Choong? Thanks again for sharing, your design seems very efficient.
