Sallyg: You have quite a diversity of plants. I just have 6 indoor jade plants.
My jades are more like your "library plants." The don't move from the windowsill. They also don't get enough sunlight, although I've taken steps to improve that. Now, my mini blinds are wide-open, rather than 3/4 closed, which helps considerably, and rotate my plants every few hours daily, in an attempt to catch more direct sunlight.
Unfortunately, I have hindered the growth of the plants. Compared to some of the other jade photos that have been shared with me, my 2 year old plants look like they are still in their infancy. It is what it is. They are very healthy, and happy plants.
Plus, The soil takes over a week to dry out, and that doesn't help with the gnats, either. So, it's a one-two punch of BTL for the larvae, and sticky traps for the adult fungus gnats.
Thanks Sallyg for the feedback.
