Terpene Freezing Point and Hash Washing

๐Ÿ’ง Extraction First mentioned: Ep. 094

A theory proposed by Fletcher (Archive) explaining why some high-terpene varieties fail to produce hash when washed or dry-sifted: certain terpenes have freezing points well below 32F/0C, so even in ice water the trichome heads remain semi-liquid and burst rather than snapping cleanly off the stalk. If the terpene-to-THC ratio is too high, the resin never solidifies enough to be mechanically separated.

THC becomes solid below about 65F. Varieties with high THC AND high terpenes may wash better because the THC provides enough solid structure to stabilize greasy resin heads. Fletcher's HP13 example: tons of smell and flavor but extremely greasy, low potency, wouldn't wash -- resin felt like oil on fingers, not sticky. Sam confirmed related observations about haze varieties remaining greasy even after months of curing.
