We have a 16 x 30' greenhouse that we have always wanted to build a raised bed inside of so that we could garden all year. This spring we finally did it! The bed is 18' 9" long by 3' 9" wide, with a height close to 3 feet above ground, perfect for sitting on the sides while working in the bed or just enjoying the ambiance of the greenhouse. We are currently harvesting many varieties of lettuce, bok choy, collards, spinach, mustard greens, and several varieties of tomatoes are going crazy, along with eggplant, peppers, walla walla sweet onions, cabbage and dill.
