Unknown pest on plants and walls
I seem to have some sort of pest I've never seen before. I guess I don't know if it is a harmful pest, but I've never seen these things in all my years of indoor growing.
They're these tiny, brown/dark maroon, almost teardrop-shaped pods/shells. It's almost like they're some sort of tiny cocoon. But there are several of them - probably a hundred scattered about - always attached to something, and under the direct light.
They're attached to the walls and leaves of many of my plants. One of the pictures shows one of these hard-shelled "pods" attached to a grapefruit leaf. The other is shown next to a dime in order to give a grasp of size.
