Hi, @florio. Well done with the garden. I've just looked at some of your harvest posts and that broccoli for new years looked especially tasty!
Have you ever heard of Rick Austin, The Survivalist Gardener?
I have his garden book and I have seen a presentation he did on his greenhouse build. Pretty cool stuff. Only thing I'd question so far on what I've see from him is that he keeps his rabbit cages on a wire shelf in the greenhouse, their dropping become fertilizer, but as I understand it, rabbits need access to their poop. Other than that, I am super excited to put into action what I've seen him do.

I see he has a livestock book now too.

Keep kicking ass in the garden!
