Yeah, I won't be caught without a T-stat. I'll be getting the hydrofarm one.

RetiredJedi- do you have anything else with your T-stat to regulate it or something? I was told to like, put a piece of glass or something underneath one so it would heat up slower and cool down slower with the on/off t-stat. But I don't think I'd need to with an ultratherm that doesn't get too hot.
