Moving Bed Bio-Film Reactor (MBBR) to replace Hydroton/Coco/Lava

Check out the root structure of my plants in this thread, that’s how they work in a hempy cup/bucket, they only populate the area where the water is. All of the other root has air directly in touch with the media. Bottom third is the reservoir and the remaining is just air with the perlite (or in this case MBBR)

Check it out.
