I thought Herpstat was designed so it could NOT fail on the On position?
One of my VE's turned out to be a lemon. Ticked about that, and had to use a spare HydroFarm in its place.
Waste of money!
Would like to get another snake, but need to upgrade the three I have to Herpstats first. I don't like the Hydro temp swing, but it has proven to me to be the more reliable t-stat.
I've heard of chaining two for a backup, but never done it.
