garden outside my bedroom is framed with a very low straw
bale wall. I set the bales up on cement blocks, so they wouldn't
get damp from the ground. They are held in place with rebar
that goes into the ground. Then, I roofed them with some leftover
material from the house construction. They stayed this way
for 5 years, and then I wired and stuccoed it, staining the
stucco with ferrous sulfate fertilizer mixed in water and
sponged over the dried sutcco.The tub is made from bricks,
earth and stucco, with a lawn sprinkler plumbed into the bottom.
It's all I need to cool off in a hot summer.
