THe white thing is for a wireless thermometer that is inside my house. It tells me the temp and humidity.I live in Socal so it doesnt get very cold. i did bring him in the couple night it got below freezing.
I think its great that you are able to keep your tortoise outside year-round. This is SO much better for his mental and physical well-being. Good for you!!!
So now we just have to figure out how to keep your little electrical pieces dry if it rains. I guess you can build some sort of box-like affair that goes over the whole corner, keeping it dry. Just something to use on those occasions when it is wetter than normal??? An umbrella would semi-work, unless the wind were to blow the water in sideways. I guess even a tarp over that corner might work out. This is such an inventive group, I'm sure someone will come up with a solution for you.
