Hi all, I found this tray in my basement and was wondering if it would work as a humidity tray. I am planning on putting my bonsai on the bumpy parts. Thanks!

The effects of humidity trays is negligible.

If the humidity tray does not provide substantial humidity, what would I use to do so?

Nature.

In the room with my tropicals there are three large aquariums pumping water into the air. The humidity spreads into the rest of the house immediately. You would have to deal the plants up and that would stop any air circulation.
