The THC molecule is made from carbon, hydrogen and oxygen, and it seems to be true for all cannabinoids. So if we can extract the cannabinoids but leave the rest of the organic compounds (big "if", I know), one could theoretically recycle the other required nutrients. In which case a steady supply of sugar might indeed be enough for the most part.
