Kathy, Sorry I didn't reply to a couple of your questions. The bins contain orchid potting materials. That shady pic is looking to the south east in late afternoon. That 10' block wall is the east end of my lot, so in summer I'll get no sun till late morning. At this time of year the sun is still a bit on the southern horizon. In the winter the sun is low in the south, so I get good light most of the day. I'll have to watch it closely and move things as needed. That area is a natural breezway, so I think I'll have to put shadecloth on the ends to slow the winds when they get bad. I'll also have to rig some misters for humidity and heat soon. This week the temps are at 66, and humidity at 81%, but when summer really arrives it will be a lot hotter and dryer.
A prefab greenhouse would have been far easier, and cheaper, but I would still have these issues, and I couldn't find one that I could fit in anywhere without removing a tree.
