I use the brown natural parchment placed on a baking sheet in a cedar box in a 60 degree room. I plan on getting a wine cooler fridge eventually. The 150-200 watt ones are extremely expensive. The cheaper ones pull 1500 watts.
You can get natural parchement at Target. It's hanging next to the pots and pans. It's not in the same aisle as the other brands. or there's Raw brand you can get on amazon
