We use horse bedding pellets too, have for years. Just this year in our brooders though...game changer!It's only about 20' from my kitchen so that would probably work. Thanks for the suggestion. I had stumbled across that light and/or some very similar items that seem to be able to do the auto on OR auto off, but not at the same time. I'll keep looking and hopefully something turns up that can handle both.
In the meantime, I'll work on some repositioning possibilities and try to get all the coffee grounds out of there. The pelletized bedding is cheap enough that I am okay starting over in there. I've got another 4-5 bags in my garage, as-is.
