Temperature Humidity

Temperature and humidity are environmental factors rather than terpenes themselves, but they fundamentally influence terpene expression and preservation in cannabis plants. During cultivation, these conditions affect which volatile compounds plants synthesize and accumulate—higher heat can drive certain monoterpenes while lower temperatures may favor others. Post-harvest, temperature and humidity directly determine terpene retention; improper storage conditions cause volatile compounds to degrade or evaporate. Breeders and cultivators monitor these variables to stabilize desired aromatic profiles across growing cycles.

Breeders selecting for specific terpene profiles must account for how environmental conditions interact with genetic expression. Stable growth environments help isolate which traits are genetically fixed versus environmentally induced, improving breeding consistency.
