Thank you, Im no stranger to electrical or electronics. Part of my plan was to use a RaspberryPI to monitor and control the heat, light, and humidity of the enclosure.. But that is to come. As for personally wiring up the heating element or device, why would I need an electrician to do so? Im in BC, I just moved here from Ontario, and Iv never herd of that. Other then running the mains conductor from the pole thru to the pannel, Iv wired everything else up in the house from the pannel to the outlets, and building electronic devices.

an 11" x 12" and an additional 3" x 11" patch of flexwatt or generic heat tape was what I was thinking, that would give me the 16" coverage I need for the 1/3 rule. Wired in parallel. Controled by a thermostat of course.
