Better stock up on 60W bulbs. They are becoming outlawed.
(Only kidding, a resistor works as well.)
Also, a foam drink cooler will give a more stable temperature. You can make it leak a bit of heat to get the thermostat to cycle. The hard part is the thermostat; they aren't cheap - even the low cost ones at the hardware store that work on low voltage.

When I did this for testing labs, I took a cardboard box, a 60w
incadescent light bulb, and a cheap thermostat. Set the thermostat to
a bit above max ambient and you are good to go. For more precise temp
control, put a fan in the box to prevent temperature startification.
