I have a larger PVC hoop house that is more or less permanent. I also have a second one in progress, but ran out of money for the clips and screen. I can stand up in both of them and they span raised beds (a walkway in the center between two beds) In other threads, I think I have mentioned that I abandoned bird net and deer net in favor of fiberglass screen which is what I use exclusively now. It lasts a lot longer than birdnet and keeps the bugs out. Besides the robins, I have two other pests to deal with. One is Japanese beetles and the other is a fruit eating wasp. They would both do a lot of damage if I did not use the screen. The wasps pollinate my raspberries, but do major damage on the fruit, so I leave my raspberries uncovered until the fruit starts to develop.
Your screened house is a lot like many others that I have heard about. It seems to be a popular approach in CA. I've seen pictures of people that erect pole frameworks high enough to span trees - 10 feet or more high. They then permanently erect screen or bird net, depending on needs. It's really nice to be able to garden outdoors, but not worry too much about the various pests. Sometimes I'll just go out to my screened hoop house and sit for a while, just to relax.
Our robins show up in early spring and then stay for the whole season - we still have robins here, even though we are now getting frosts.
Where robins are concerned, diversionary crops just do not work. I've planned my fruits so that there is something that should be ripening all year long (May through October) and the constant pressure of the robins makes them a problem all season long. I also am limited on space, so could not grow a lot of excess to share with them.
I am a fan of Autumn Olive, but they are considered invasive in many places (not here) and I do not know if they will grow in FL. However, they can be highly productive and are very easy.
