Lost space?

[terrestrial_man]

Just wondering if there are any great suggestions on what to do with the space under the plant benches.

At the moment most of this space is just used for storage of my jugs of r/o water and some unused aquariums and pots and one aquarium with aquatic plants in it including an aquatic moss, Java Moss.

Just like about every surface in my greenhouse, the area gets a good soaking when I spray down the greenhouse to push up the humidity. So my own use of this "dead" space seems pretty well restricted.
