I have constructed a small shelf attached to the south side of the orchid room to hold the Zygopetalum seedlings. I have had them in shady, non-direct light, areas (first in the kitchen, and second on the upper shelf of the orchid shelves). This is the first time that they will receive bright diffused light, and we’ll see how they do.
The shelf will probably need a post, as it is heavy. I don’t anticipate putting heavy things on it, or large plants on it, but to use it for light things, like seedlings.
