If you have any soil layers, the easiest would be just to hollow out a big room with soil floors (make sure sunlight never touches it, or it'll permanently only grow surface plants). Once you breach a cavern that contains cave fungus, spores will start growing the treelike cavern mushrooms all over the undergorund soil.
Supposedly you can use cave-ins to move blocks of soil down to a lower level if it's more convenient, but keep in mind the whole "Once exposed to sunlight, always exposed to sunlight" rule.
Keep digging!

Imagine them making a moat around your fort to try to starve you out.
