Here is another wonderful tutorial inspired by Niki’s book : The The Year-Round Vegetable Gardener: How to Grow Your Own Food 365 Days a Year
19. Cold Frame Along Masonry Wall
This one runs the length of a stone wall, facing south : ideal spot for a cold frame, as the stone (concrete works too) absorbs solar energy during the day and radiates it back out at night. ( Deep Roots At Home )
20. CD Case DIY Greenhouse
CD cases open and close, how smart! Meg‘s tutorial is filled with great details!
21. Simple Cold Frame and mini greenhouse
In Rob’s Northeast garden, plants such as lettuce, kale, broccoli, were able to survive the sub-zero weather in these cozy cold frames. He has some fabulous free plans of DIY cold frames and DIY greenhouses to download. ( Bepa’s Garden )
22, 23. Easy to build A-frame greenhouses
24. Super Easy DIY Hoop House
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. ( QT’s Random Ramblings )
25. Trampoline Hoop House with Passive Heating
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.
I also LOVE the use of old jugs that have been spray painted black. They are filled with water. During the day the water heats up, and at the night, they radiate extra warmth inside of the greenhouse! ( Heather | How Does She )
26. Mini Box DIY Greenhouse
Anne‘s simple and beautiful DIY greenhouse is made from old windows, and the box shape makes it easy to build!
27. Retractable Hoop House
The smart design makes it easy to work on the garden beds! The hoop house is framed with o.5″ PVC pipe. They fit into 1″ diameter tees that glide over the aluminum pipe rails that are 3/4-inch-diameter. The garden beds are from 8-foot-long, 2-by-6-inch untreated fir.(Grit )
28. Hinged cover DIY greenhouse
Stephanie‘s greenhouse has a hinged cover on top of a raised bed: an easier way to remove the greenhouse cover!
