// Definition
Sulfur-containing aromatic compounds in cannabis responsible for the 'dank' and 'gassy' smell profiles. These volatile sulfur compounds (VSCs) are derived from sulfate uptake through soil bacteria, liberated as H2S, and converted by the plant into thiols and thioates through amino acid metabolism. They are far more potent odorants than terpenes at equivalent concentrations.
// From the Episode
Bubbleman discusses how certain strains like Renee and UK Cheese have aromas that transfer through water without dissipation — suggesting these are thiols and thioates rather than terpenes. He suspects the dankest strains owe their pungency to sulfur compounds rather than traditional monoterpenes. Discussion of how sulfur from soil amendments (magnesium sulfate, calcium sulfate/gypsum) feeds through soil bacteria into plant amino acid pathways. The connection between sulfur nutrition, soil biology, and eventual aromatic expression represents a frontier in cannabis cultivation science.
