okay i have heat wave, terrarium substrate heater from exo terra. 10" x 11" 16 watts.

okay so here's my problem. the temps in my viv are reading 79 degrees. is this going to be warm enough for dexter? the cool side is approx 73 degrees.

i have this stuck right on the plastic rubbermaid container. i'm using an inch or more of aspen shavings.

yes, my temp probe is taped to the bottom of the viv under the aspen.

darn it this heater cost me $35!!!

we have not added a rheostat yet, but if we did, could we make it warmer that way?
