From what I just looked up hempy buckets are basically filled with coco and a perlite below with a hole for water to exit a couple inches up from bottom with fresh water being supplied.
My plants roots grew out of the pots sitting in the openings of the jar rims. The roots went into the bubbling nutrient solution that was just below the bottom of the net pot, the roots loved the bubbling water and grew huge.
I have learned that maybe the bubbling water is not needed to keep the roots from rotting and only an air space is what is required between the bottom of pots and water surface, will have to test the difference some day as I would like to run a couple cannabis plants this way.

It's similar to your cloner but a single unit.
