There appears to be a slight slope on the tin but there won't be enough water to worry about. Just occasional spraying to keep it moist and add some humidity. Might hang some plastic gutter up on the lattice behind the plants for like a green wall but that would block the light so scratch that. Maybe put the gutter on the house wall behind me. Hmmm, my brain is too active.
Have socks on this morning, no carpet in the house and no fireplace. Down close to 60f again.
Off to breakfast at the Volcano House restaurant this morning. Looks right out over the rim of the caldera if its not socked in with cloud.
