Anyone searching for detailed info on growing Eleocharis dulcis, I found a very in-depth feasibility study that was done in Hawaii which discusses things like climate, temperature, soil fertility, how deep to plant, etc... Very thorough and helpful. Even for those of us in colder climates.

I would attach the document if I could figure out how, but am working with a computer that is new to me and unable to figure out how.
--- good luck
