This wall is composed of pressboard, and absorbed any humidity from misting almost immediately. An inexpensive, very thin plastic painters dropcloth tacked to the wall solved the problem. The plastic lattice ($12) allows me to hange such things as plastic lizards on the wall. The tomatoes are doing nicely, but they will have to go if I want orchids to bloom here, they will have to go. The ripening tomatoes produce ethylene gas which caused orchid blossoms to drop off.
