They should be.. if they get dry.. they will die off/air prune. If you cover the tray from the light, those roots may keep growing.

Not gonna hurt anything. They will prune themselves if they can't live. All the roots that matter are inside the cube
I became worried because my cubes were a little dry and was hoping they were able to get water from the roots that are in the tray out of the cubes

Yes, the roots that are in the grooves of the flood tray where water stands for a couple of hours should still be alive. In an ebb and flow hydroponic system, the roots are designed to withstand periods of flooding and draining. However, the key here is oxygen. Even though the roots are submerged in water, they still need access to oxygen to survive.

With a coco mat and some panda film, the roots can truly thrive in a flood tray.

As long as it doesn't go completely dry, you're good. A little dryback forces the roots to search for water, too much causes ph, ec, and other issues.
