I was speaking to a friend recently who has a bunch of money to invest in her horse farm. Her goal is to cut out some expenses by doing more herself. One thing she really wanted was fresh grass for her horses during the winter months. I suggested that she build a greenhouse attached to the barn, equiped with lights, humidity control.... basically the works. She also liked the idea that it could be used during the winter to grow veges. Anybody out there done a similar project?
