Just received my Hydrofarm in the mail, yesterday. I don't plan on breeding snakes, just owning one.
I understand that when breeding, you should have an incredibly accurate t-stat, such as the acclaimed Herpstats, VE's, etc.
But, these H-farms have such raving reviews! Worrying about the 2 degree fluctuation, imo, is kinda silly. If your cage/tank/whatever isn't insulated enough to hold 2 extra degrees inside, for a minute or two, something must be wrong with your enclosure... Down the road I do intend on picking up a VE, and I'm fairly sure the H-farm will be one hell of a fail-safe! Got change for a nickel? There's my 2 cents.
