We ran into a similar problem a few years back. We ended up reusing some greenhouse plastic and wood we had lying around to make some short greenhouse covers similar to the image below. We got the grow plastic here if you are interested. https://jigglygreenhouse.com/store/
When we first started out, we built a small growing tent using greenhouse materials. That way we could do more vertical growing in a smaller space. Just a simple shelving structure wrapped in UV plastic with some good sized pots got us a small but goof harvest early on. We got our supplies here...
