I'm waiting for the day when cannabis will be grown in full-par bio-luminescent biotic fluid that is impervious to molds, mildews & pests, and is infused with varied strata of microbes that process their environment based on the plants needs by creating exactly perfect amounts of nutrients, oxygenating the fluid in the rootzone with perfect amounts of oxygen, both based on biofeedback properties of the fluid and microbes, and then microbes of a lower specific gravity above them would convert the Oxygen to CO2 for the rest of the plant and then collect the Oxygen at the top of the fluid to re-infuse at the bottom of the tank for recycling.
Then, come harvest time, the microbes form strategic alliances and develop Weapons of Nano Destruction and wage war on each other, destroying the small stems where the buds attach to branches and where leaves attach to stems (neatly stacking & storing said leaves for convenient hash processing, and stems for composting).
When all buds are separated, and the microbes have killed each other off, the buds dry (the biotic fluid absorbs 38% of all moisture) and cure, in situ, to protect from mold & mildews until the biotic fluid is drained & strained to collect any errant THC heads lost as collateral damage in "The Microbe War To End All Microbe Wars" and make pure bubble with.
The biotic fluid is actually a "canna-phobic" fluid and no traces remain on the plant or cannabanoids once the growth tank is drained.
Just my wild imagination...
... or
IS it!?
