watching the thermometers

My gardening has turned into watching the thermometers from inside the window. The bigger monitor has a sensor inside my cold frame, and the little one is outside. (The balmy 63.3 is inside the house.) I took this photo on a recent chilly night. The cold frame stays warmer when the temps dip low. They go up quite a bit when in the morning when I get a bit of sun on the frame. But right now, as I look, outside is 55* and inside the frame is 50*. The greens inside are still OK. I picked a dinner of broccoli by flash light last night - 2 minutes from garden to pan. I love it!
