I'm planning on getting the T3 and am considering on getting the 11" flexwatt to go with it. That is slightly less than 1/3 of the cage.. does the flexwatt seem to heat enough to be a singular heat source? My room temp is 70-75. Would a Zoo Med UTH work better (I could get a larger one)? Either one, I'd probably use with a Hydrofarm thermostat.
