I think aquaponics are a very viable solution. If we are to be using Anti grav it's very usable. If it is induced gravity there is a little more challenge but still vary possible

There's still a possibility of making it into space in our lifetime. Scientific research has allowed for an ever increasing technological advancement. Before you know it, we'll already be up there. Things may start off slow but if enough people are working on the cause, the time from project start to project end ( or at least the interesting parts) will be drastically shortened. Especially if more of the Asgardian community chip in to help advance our project. It will only take years if we do not act ourselves as a collective in good time. I'm hoping that a majority of this community will help fund the project and become much more involved. The food we eat up there could be the same food we eat down here. We just need a good artificial biosphere.
