I use these, but wind is a problem so heavy water containers on the bottom shelf.
Right now I have a 4 foot by 6 foot walk in one.
It is good for holding plants as they harden, but I lost half my petunias when I was away---- and it turned warm.
Over the summer I can do peppers, eggplant and one or two tomatoes in there.
The shelf kind are good for seedlings, but vigilance is necessary if the door is zipped closed.
These are temporary solutions only. If I were planning on staying in this home, then I would go
for a proper greenhouse.
