wow, a very detailed and nice job you have there however the lamps that you used will actually causes electrocution due to the condensation during winter.....and the styrofoam box that you used might melt after long term running...hmm....you might want to do a test runs with the 'dampen potting medium' first before putting your babies inside...suggest you might need to use other material for the lid since all the electrical accesories are located on the lid.....
just my 2 cents
