Ive been planning on building a temperature and humidity controlled cabinet. i was planning on building out of wood but when faced with the cost of plywood i started thinking of other methods. i had an idea to use a refrigerator box lined with styrofoam and painted inside and out with drylock concrete sealer to guard against humidity. i would use a 2x2 in each corner and around the top for added stability. shelves attached to these supports. a zoo med reptifogger would be placed on top and run thru a hole to provide humidity. i have a zoomed temp and humidity controler that would be hooked up as well. a glass cabinet door on front. the whole thing would be placed inside one of those big trays u get to go under ur washing machine so any extra humidty would go there instead of the floor. would elevate the box about 2 inches so it wouldnt be sitting in any water collected at the bottom. also 4 computer fans will be wired and placed on a timer to cut on every six hrs or so for a couple of minutes. to me this sounds like a good idea but i wanted some opinions from the community. also im not sure how to heat this beast. as humidity will be high im concerned about a short resulting in fire. any ideas or critiques to the design would be greatly appreciated
