Keywords i keep hearing about Hydrofarms is , YET,AT LEAST,WEEKS,MONTHS,VARYING DEGREES,BUT.
Thoses that use it, may get a good unit but these were designed cheap for the use of gardening. They were designed for seasonal use and not 24/7 365 use. They most likely fail in the ON position where your snakes will be fried. I Just couldnt trust them with larger collections that have Thousands invested. If you cant afford a good thermostat, Sell something to get the funds.
When buying the better thermostats, their programed to fail in OFF position. Always remember, your better off with a snake that got cold rather HOT and suffer problems from it.
