OK, I have an idea that I am wanting some forseeable issues with... I am pretty excited about it and will probably try it even if it does end up failing miserably.
So Here goes-
I am cobbing a 2 foot wide base around my house/greenhouse to be, then framing up a space above it about 3' wide by 6' high and the same 2' in depth as the cob foundation. Then covering the framing in plastic and putting a slanted piece of metal barn siding at the base (touching the cob).
Then, covering the framed rectangle, front and back with either hardward cloth or lath. Maybe some mosquito netting too.
Then, filling the "boxes" with dirt and cobbing around the frame.
The slanted barn siding at the bottom is for drainage. Sufficient overhand over the cob foundation so it doesn't soak the cob.
The idea here is to have more growing room and to get walls up quicker than it would take if I were cobbing the whole thing.
I still need to devise an efficient way to water everything from the top, but that shouldn't be too hard.
Will a depth of 2' of soil be enough to retain the interior temp of the house? Or will it just go right through the soil? Soil seems to keep it's 50-60 degree temp pretty well but I'm not sure about at only a 2' depth.
Will bugs get in through the dirt?
Other issues? Mold, yucky stuff in general?
Ideally there would be stuff growing on/in the walls year round, especially on the interior of the house.
I know there are "living wall kits" out there but this would be a wayyyy easier and cheaper solution than those things.
