2. Pallet Greenhouse Cold Frame
This is another smaller greenhouse cold frame set-up. It is great for hardening off seeds, giving some plants an earlier growing season, and giving other plants a longer growing season.
So if you have a small open area in your yard, then you could easily construct this design for a greenhouse.
Though you’d have to basically work from the pictures instead of having an actual tutorial, if you have any building experience, you could probably figure this out.
3. The Pallet Window Cold Frame
This is another pallet greenhouse idea. It doesn’t have a tutorial, but if you have any building experience, you’ll probably be able to figure this out.
So you’ll use the pallets to construct the box. Then use old windows to construct the doors on it so the sunlight can get through.
Again, this type of cold frame is great because it doesn’t take up a ton of space, but yet you can still grow plenty in them.
