In my colonizing business, some colonists build a underwater base on a all-about nice planet. They are using food storage right now; but now they need to start farming. Ive looked up some farming things. They have set aside lots of resources and space to build the farm, whatever it is.
My question is:
How can I make large industrial scale underwater farming?
What can they farm, animals and plants?
I live in a agricultural community so I will understand agricultural stuff.
