What's happening in the jar depends on how you grow from my observations.
Hydro growers are waiting for unprocessed nutes to be broken down while rehydrating the exterior of the dead plant to give it a simulated texture of a more resinous, danker bud, while also attempting to preserve perpetually offgassing
terpenes created before harvest.
Soil growers are letting the living plant continue to produce new isoprenoids and store them in its fatty tissue, while periodically providing fresh air to endophytes responsible for converting starches into sugars, sugars into alcohols, acids into thiols, etc as the plant slowly dries out and never realizes nor experiences a definable moment of death.
Thats just the way I see things. Organic bud glows like a rooted plant on shrooms. Hydro is as radiant as the plastic ficus in the corner.. 2 different products, 2 different processes. I'm not saying one is a waste of time or anything, but people gotta realize the question has 2 different answers depending on if you're talking about natural or synthetically grown pot.
