yeah i agree with this guy enzymes eat protiens AKA dead roots but it well probley take a while you might try screening the big stuffmaybe hygrozyme? I heard someone say they use worms, then pull them out. I just mix the hell out of it and let it sit nice and moist for a little bit. That being said I think you should look further into reusing coco with your growing techniques, I've heard bad things about reusing.
cannazym is what you are referring to. Rhizo is a stress reducer.Rizotonic...Canna Nutes.
