Tori, there's a whole thread (started 2yr. ago) about that Harbor Frieght greenhouse you mention above. Lots of advice and tips on what to add and how to make it work better. As with most things from HF, it's not . . . ahhh, shall we say perfect? But a good value.
Be sure to scroll down to Dave's first post, because strangely enough it starts out talking about one from Home Depot.
