That is a fantastic post! And to have an ACTION recipe that allows people to kick of and run such a gardeners lab would be fantastic.
###ACTION size
I wonder how it could be approached the best way with the ACTION protocol idea. In the Meta-ACTION about ACTIONS we assumed, that bigger projects need to be broken down into smaller parts. So people can do first steps without a big longterm commitment. Test the waters. If it can be done with an event it might be good, because events allow to motivate people to do stuff. People come because there is no longterm commitment asked for. But you can see if there is the energy for it.
So what could be a fun first step - a fun part – easy to set up but working in the longterm vision of such a gardeners lab with connected modules.
###Build a first module?
Probably, as you are suggesting, to start with one of the modules. Set up one module. And this in a way, that it can be later connected to other modules and maintained with the methodology you describe (3-5 people etc.)
What would be a cool first module to test it?

(Some loose ideas that come to mind @dax is working a lot with mushrooms and do you know Valentinas biogas digester? I think there are a lot of Open Source resources on urban gardening are out there. It is probably good to start with something that is well documented already? But you listed such inspiring module ideas already.)
(Ps. If there is something to build for the module I am happy to throw myself in to help figure out a way how to build it with the 3erlin Grid and local circular materials.)
