Spent a bundle getting a robust watering system installed in the way back yard. Then we started getting freezing weather at night. The valve that feeds the system could easily freeze and burst the pipe, so I decided to enclose it. Simple project to build a box large enough to cover it and got me out into the shop again. Made it of redwood fencing, and it will be lined with 2 inch foam. Will likely add a number of nice sized rocks to hold heat. For wood that cost less than 2 buck a board, it turned out to be a fairly precise piece of work. The lid on top will get a solid covering in case of rain. I'll give it a month of manual operation to make sure nothing leaks, then wire it up to a controller for automatic weekly watering.
