Thermal Processing

Thermal processing in cannabis genetics refers to the spectrum of post-harvest heat applications—drying, curing, roasting, and decarboxylation—that modify cannabinoid profiles, terpene expression, and plant material structure. These techniques convert THCA to THC and CBDA to CBD through controlled temperature exposure, fundamentally altering the chemical composition from fresh plant matter. Breeders and cultivators document how different genetics respond variably to thermal stress; some lineages retain volatile terpenes better under low-temperature drying, while others show stability across broader temperature ranges. Understanding thermal processing is essential for lineage preservation, as storage conditions and heat exposure directly influence long-term cannabinoid stability and degradation pathways. This family encompasses both intentional processing methods and incidental heat expos

Breeders select for thermal stability and decarboxylation efficiency when developing cultivars intended for specific processing workflows. Lineages with robust cell structures and stable terpene profiles under heat are prioritized for commercial extraction, infusion, and long-shelf-life applications.
