I can day-dream about them all day long … greenhouses and cold frames!
Far and wide I searched, to gather some of the BEST tutorials on how to build amazing DIY greenhouses from tiny to magnificent.
Every one of these is a labor of love. You will find ingenious ideas from passive heating elements of painted jugs, straw bale as building material that needs no tools, to using tree branches, old bottles, windows, and even a trampoline!

Before we dive in, I want to share with you two of my FAVORITE books on greenhouse gardening-
The classic is Four Season Harvest: Organic Vegetables from Your Home Garden All Year Long by Elliot Colman. He gardens year round in cold Vermont, and shares simple, inexpensive designs for cold frames, unheated mobile greenhouses, and root cellars in this amazing book.
The new ground breaking ( literally) book The Forest Garden Greenhouse is written by the brilliant permaculture designer Jerome Osentowski who grows bananas and citrus on a rocky hillside in Colorado with winters in -30s.
1. Cut Bottle Mini Greenhouses
The easiest 1-minute greenhouse, yet surprisingly effective. Check out the 3 secrets to success! ( A Piece Of Rainbow )
2. Cedar Branch Hoop House
Find a good quality greenhouse plastic.
The cedar hoop can last 30 years! If you have Cedar or other rot resistant trees where you live, they can be an attractive and all-natural alternative to PVC pipes. ( Earth Easy )
3. Hardware Fencing Hoop House
Great idea to combine straw bale gardening with hoop house design! The livestock panels used here are a heavy gauge galvanized welded wire fencing material. The plastic cover can be removable to allow beans, gourds etc to grow in the summer! ( Dave’s Garden , and Peak Prosperity )
4. Pallet Greenhouse
Having 2 greenhouses is 8 times more amazing! ( The Green Lever )
Here’s our favorite tool for taking apart pallets – a Duckbill Deck Wrecker that makes it so fast and easy!

5. Hoop House Over Garden Bed
Two variations of PVC hoop houses over garden beds – first one has a great video showing how to secure the PVC onto rebar stakes, while in second one the PVC goes into the ground directly. ( Bonnie Plants , and Whole Lifestyle Nutrition)
6. Straw Bale Cold Frame
So simple and so ingenious! Straw Bales hold the heat as walls that need no tools to construct, just add windows or plastic, and frame. I especially like the first design where the frame is sloped towards the south with tiers of growing space! ( High Mowing Seeds )
