I am about to embark on a similar journey. We are putting together a 220 litre cube made of 25mm laminated  mdf (500mm x 500mm x 1000mm) to hold a 60 litre Carboy/vat as we brew double batches of beer. We have done some research into the thermal properties of the mdf and it would appear to be ok.  The vat hold about 48 litres of brew and is usually started within a few degrees of the required temp. The cube is in my shed which may get to 30 occasionally but not often as it's quite sheltered from the sun. It does get down to single digits in winter though. I would expect that the cube will require very little temp adjustment during fermentation. The shed is typically low 20s most of the year.  I get what you are doing, which is pretty much what I am doing but I was wondering about more of the exact details.  1.  How many watts is your peltier and what are the specifics of the transformer that drive it? 2.  Is there any advantage in getting a higher watt peltier and if so, what is the impact on the transformer? 3.  What specs do you think I would need to use to achieve the desired results. Ie 2 peltiers?  I am currently brewing beer at 22c (yeast pitched at 25c) but would like to try lagers at about 10-12c so the temp control will need to be able to maintain that.  Thanks in advance.  This is really interesting.
