I guess the big question I have is how much of earthing would be needed in hot and humid weather here in eastern NC and with that, how much load would that put on the rafters? Is soil "rammed" down before applying "grass" on it? I imagine that grass was grow to help prevent erosion during the rain.

Any thought on earthing siding? I honestly would not mind adobe style on the side out of TF structure after TF has been raised because I like adobe house design myself but I'm not sure how it can handle humid weather since its more favorable in dry area such as AZ, NM, and southwest states. I read that AZ and NM has less restriction on self built adobe home using earthing since its pretty common down there while in other part such as CA and TX, permit is required. The one seen at calearthorg website is more arrtactive to me (exterior part).

Thanks!
