Hey everyone. I see that there is a workshop in GA In april.
But I also found a man who runs a workshop all year in texas. He provides videos on this website showing the entire process you can buy to learn the ropes. He also goes beyond the workshop teaching you how to finish, do plumbing and electric to bring it up to code.
I won't say his name but you can find it through youtube if you look up aircrete dome.
He also has private workshops that you can pick out the topics you will go over.
