I am building my first enclosure, and i would like to heat it by using flex watt. The Dimensions are 36 x 24 and 16 high. is it possible to only heat this with only flex watt, i wanted to use 2 pieces, both 11inches wide and 12 long. one on the warm side to 90-92 and the other to about 82-84 to think this will keep a good ambient temp in the cage. i will be using 3 digital thermometer and i am trying to buy a thermostat off ebay, there is a guy right in my town that has one on ebay, but i dont think i can really afford it this week. so anyone let me know if this setup is gonna work
