I'm having trouble creating a basking spot for my royal python, I'm using a dimming thermostat which is powering a 100watt ceramic bulb/heat emitter but the temperature stays the same through out the viv (28-29c). The sensor is about 9'' away the heat source can I move it away to get the temps for the basking spot,

I've worked with snakes before but we never used a thermostat in an individual viv as the the whole roomwas heated, do I need an extra heat source?

The viv dimension are L3' W1.5' H1.5'

regards
