I'd like to experiment more with microclimates. I have great growing conditions but my property is a field, and reducing wind and cold as a factor would be very helpful.
I need some ideas for materials and techniques that are cheap, fairly durable, and hold heat well. Thoughts?
The cob, maybe topped with flat stones, could be good.
Charcoal or lampblack could be used to blacken your plaster.
The strawbale wall would be insulative, but not a thermal mass.
Strawbales on the north side of the wall, water barrels on the south, roof feeding water into the barrels, and a big olla buried deep in the tree planting hole, feed directly from the barrels.
Maybe grow azolla fern in the barrel and toss in some koi it goldfish.
