Info on building a greenhouse

Do a search at Hometalk or use the browse, there have been a number of good ones made from things that they had laying around.

I've seen them done with screen doors, windows, plexiglass, extra plywood and lumber. Repurpose pallets for wood or use as walls and cover with heavy plastic. Depends on how big and elaborate you are thinking. Are you wanting to leave it up or disassemble in the spring? Food for thought

Since we don't know what you have lying about... I will refer you to YouTube videos on how to build a greenhouse which can be from recycled soda bottles, to flexible PVC pipe and plastic sheeting, to old windows..... https://www.youtube.com/watch?v=2PXscRG3yXw

If you need free materials, I sometimes use Freecycle.org to get materials like windows. Join for your state and town, and simply post a wanted post. And if any member has the item, you just need to go pick it up.

Gete two books:

The Solar Greenhouse Book by James C. McCullagh and Greenhouse Gardener's Companion by Shane Smith. Both are excellent books telling you everything you need to know from the direction it should be placed, to heating to what plants grow best for year round gardening. Easier than taking notes from things on-line.

A greenhouse can be as simple as a wooden frame shed type structure made from pallet or scrap wood covered in a skin of vapour barrier plastic, you could also make it from recycled windows and doors if you want to get fancier or pvc tubing in a hoop shape covered in plastic
