water chestnuts

Hi there, I would love to hear your experience, methods and yields in growing water chestnuts.
I'm in South Carolina, zone 7b.
Thank you so much you fabulous growers

also- Is there a forum for aquaculture? I'm not finding one...

My experiences in Zone 7(a) Oklahoma are mostly detailed in this thread: https://permies.com/t/159346/easier-ways-enjoy-fresh-Chinese

The short version is, they are essentially perennial here; they even survived last winter's coldest-on-record drop to thirteen below zero (F).  However I have pretty much given up on harvesting them because they don't grow as large as the ones in the Chinese grocery.  And at the sizes I can grow, they are too big a pain to peel -- to much work for not enough meat.  

I keep them around because they grow easily in very small pots and the reeds help me attract and retain dragonflies in my garden, which are an essential part of keeping pest insects under control.

The nearest we have is aquaponics which is under the building forums.
