I made this one out of an old ikea file cabinet. First I gutted the thing and cut out a hole on top for the lights. Next I glued 1in thick pink foam to the sides for cold retention then covered the whole inside with 2 coats of drylok to seal any cracks and keep the moisture away from the foam and wood.
Inside the tank is an ultrasonic fogger for humidity and a waterproof fan connected to a radiator that will have cold water/antifreeze (I havent decided yet) from a chest freezer pumped though it when I need the temp to drop.
Tonight will be the first run, wish me luck. Should it fail to get the temps I need at least I will have a new terrarium for sundews!
