Stalks of plants grown in the typical indoor grow way are only good as very low grade biomass for methane digestion or as chips that might serve in hemplime or hempcrete. An insignificant market so far as these technologies are still going through the regulatory processes to be used more widely.

There are effective dual cropping systems that can yield cannabinoids from flower and get useful fiber but it is not common yet either.
