mixing heat elements for large cage(cold room)

[Dan84]

I mentioned heating the cool side because my cold side can dip into the upper 60's even with a RHP and flexwatt on the hot side heating the ambient air. I have a 106 Qt Sterlite tub with a 40W RHP and 1.5' of 11" flexwatt. My plan for when I upgrade my boa to a 6x2 will be to use flexwatt to maintain the entire enclosure at a 73-75 minimum temp, and to use the RHP to get me to the 88 degree hot spot.

I am just offering a different approach. Just don't make any permanent installations and find what works for you. Update your post as well being that I will be in the same position as you very soon.
