Heating rack system with flexwatt and thermostat

[Spaniard]

thank you halfdawg, the 15 qt tubs would be used for a baby ball until it reached bigger size and it would be put in a 32 qt, would it be bad to run the 3inch flexwatt length wayz on each shelf (24 inch)?

Won't be bad as its commonly done in racks of your set up.

and also i would like to know the difference between ranco and johnsons thermostats, and the difference between those two and an Alife unit
thanks

Never heard of Alife but my personal opinion is this...

The success of your snakes relies heavily on temperatures so why try to cut corners when it comes to such an important part of husbandry? There isn't much difference between Rancos and Johnsons; they both control temperatures by turning off the heat element and then turning them back on in order to achieve the desired probe temperatures. I think you'll get around a 4 degree swing using a ranco or johnson.

Going a little more up the ranks and you get to Helix and Herpstat thermostats which are digitally proportional. These devices constantly adjust the flow of energy to the heat source so that the probe temperatures are always at on constant temperature.

I've used many different techniques to try and control temperatures and in the end I would have saved a lot of money if I just would have bought a quality instrument from the get go.

Good luck!
