Though it’s January, the gardening season isn’t far off. But in cold regions gardening outdoors will be still impossible without a greenhouse. A greenhouse is a great piece for growing capricious plants and flowers, or if the climate is changeable, or in case you want to continue gardening in fall or start early in spring. Decide on the size – big or just a small one, make a frame of steel, plastic or wood – wooden pallets or any recycled wood. Choose the material to cover the frame: polythene, recycled glass, plastic, glass, maybe you’ll use some old windows. Have a look at the tutorials below to choose what’s better.

Using recycled windows and a couple of old doors from another neighbor who was getting new ones installed, the author worked out this design. It’s rather big so it can accommodate a lot of plants, and I totally love the bold blue color.

Make your own row-cover hoop house using a few simple materials. Lay out your design to suit your garden. Remember that while the PVC pipe is flexible, it doesn’t flex a lot, so your frame will need to be fairly short and wide. Farm-style spun-bond row cover material is available at farm and homesteading supply stores, and frost blankets can be found at most home improvement stores.

Love the simple cross arch which is perfect for smaller raised beds like the 4′ by 6′ one here. Instead of pressure-treated lumber, consider using 2×12 redwood or cedar, which are non-toxic.

A brilliant use of an old trampoline -no cutting of the steel required- just pull the frame pieces apart and there you have 2 halves of the frame. The old jugs that have been spray painted black are filled with water. During the day the water heats up, and at the night, they radiate extra warmth inside of the greenhouse!
