I've been planing an indoor aquaponic setup.
I want to build some kind of roundish structure in my yard to grow in aprox 17' diameter and insulated.
So I'm looking to build insulated walls with natural materials that can handle high humidity and LED lights. My yard is all evergreen trees and gets very little sunlight if any.
I live in bc on the mainland in the south west corner and your ceader / clay idea sounds like it might work. Have you done any testing ? Do you think this would work ?
For the structure im considering a geodisic dome with a water proof outer skin or a circular wall with reciprocal roof.
