I prefer to grow in dirt myself.
Building rafts for residential use was common in the culture, and the gardening was done on the same raft. It's an interesting idea. More secure for its time, as well.

In the 1930s-50s, a French Canadian Indian named Joe squatted on an island on a small lake in Maine where my family has a summer camp. He built up the island by hauling dirt and rocks over the ice that would settle on the shore in the spring. (He also ran a moonshine operations — my cousin found it while scuba diving off the island.)
My mother likes to talk about how his vegetable garden was lush and productive — and about the standing family rule, “Never eat Joe’s tomatoes”.
