Found it! About the middle of the first page in the Greenhouse forum is the Harbor Freight Greenhouse Thread. On page 7 of that thread, twoards the bottom is a post with pictures. I think there are more photos after that in different posts as we all commented on the cool sun shade he built.
The thread "Harbor Freight Greenhouse projects" in
Greenhouses forum
Towards the middle from DavidDeLand who is no longer here.
