So using the 3 heat panels, one in each enclosure what would be recommended for a thermostat? I was looking at the Herpstat 4 since I will have 3 enclosures. Also with the building of the cabinets in the video he didn't show any sort of ventilation? I am trying to get a list of things together to start piecing this build together and try and get a ballpark of the cost for everything.
