What thermostat/ where to buy?

i have two 1 foot pieces of 11inch flexwatt, one cool and one warm. i put them on opposite side of a 20L tank. the middle is where i have my water dish so belly heat there isn't that important.

i would just experiment. you could maybe get a foot piece of 4" flexwatt and use that for the cool side if you have a smaller tank.

just ask Rich when ordering if he can put the cord on the flexwatt and he will do it for free.

the "cord" that is put on the flexwatt is just a standard 2 prong plug that will go right into the thermostat right?
