I used two longer planks that had actually been the sides of my trailer before I rebuilt it, and some leftover bits of what had been an insulated, heated, paneled, doghouse. (Long story.) The corner braces were made from parts of pallets I picked up for free. Topped with a couple of old windows a friend gave me after a remodeling project, and lined with black plastic left from landscaping, it's not pretty but I hope it will be enough to protect the plants. As I have time and can find a matching third window, I may refine it and try to use it for growing some greens during the off season.
|I did say 'primitive'|
Until next time, God bless, and take care, my friends.
