Plant Moisture Content

Plant moisture content refers to the water present in cannabis plant tissue, expressed as a percentage of fresh or dry weight. This is a cultivation and post-harvest metric rather than a terpene, but it significantly influences terpene preservation, volatility, and stability during drying and curing. Breeders and cultivators monitor moisture levels because excessive water can promote mold and microbial growth, while insufficient moisture may accelerate terpene loss through oxidation. Proper moisture management—typically 10–15% in cured flower—is foundational to maintaining the full aromatic and chemical profile that breeders intended. Understanding moisture dynamics helps preserve the genetic expression of terpene-rich cultivars across storage and processing.

Breeders select for plant structures and leaf density that support optimal water retention during growth and drying cycles. Cultivars bred for specific terpene profiles require controlled moisture environments to prevent degradation of volatile compounds before harvest.
