This is the guest bathroom bathtub-shower. Kinda dirty
The is "worm dirt" or worm poop, formed into a dirt clod, and a seed from Mrs. Carrera's garden from last year. The stuff already sprouting is the milkweed for the Monarch butterflies to eat. The other dirt clods have yet to sprout. She had the tubs covered with plastic wrap for a couple of weeks, so they were mini hot houses. The black thing under them is a heating pad for starting plants that is warming the plants to 75 degrees. No doubt that tub would be much cooler as it is against the east wall of the house, and porcelain. There is of course a light shining on them 24/7 right now.
