DIY greenhouse project you can make against the side of your shed or garage. I like this off an existing building instead of giving up a new space in the yard for it. It is a nice space to start without a large outlay of cash for a full size greenhouse and it doesn’t take up a lot of yard. I think this is the perfect size greenhouse to start with.
The windows can be cut from glass or plastic, and since it is against an existing building you don’t need any trusses in this greenhouse. Runnerduck shares the instructions and plenty of pictures of each step to help you build one.
