I've started using the stalks for various art projects, and we process out all the trim and fan leaves into bubble hash. We've adapted Cannabis into our life completely and I feel we should be using the whole plant. I'm looking to take it to the next level and use the roots for something as well. Any advice would be greatly appreciated! We currently run everything on a hydro system so there is just a hefty root ball in the end. It has to be good for something!?
