How about using Moving Bed Bio Reactor (MBBR) by it self as a media to sustain the root of a plant the same way that hydroton would in a hempy bucket, it’s Virgin Polyethylene, and it has no pH or any kind or holding capacity at all, which makes it perfect for hempy cups/buckets. I am gonna buy some and try it out, gonna be doing passive hydro with plastic media and force feeding the nutes!
People use this stuff to make a natural habitat for beneficial bacteria to clean the water in tanks/ponds, it’s for a self maintained water filter that never needs to be cleaned, perpetual clean water, but the plastic little thingys i wanna use as a hydroponic media to grow in hempy buckets, you know the way i did it with the perlite or doing with the coco right now, but instead i’ll use plastic pellets as media.
It would be good to re-use and super easy to clean, just pour some bleach water on it for a few minutes and it’s clean, after that just rinse it to remove any traces and VOILA!
