Hash Storage: Temperature and Time
How temperature, humidity, and oxygen exposure change hash over weeks and months — and the storage protocol professional connoisseurs actually follow.

Terpenes evaporate. Cannabinoids oxidise. Both processes accelerate with heat, light, and air exposure. A premium piece of hash stored on a sunny windowsill loses 30% of its aromatic compounds in three weeks.
The ideal storage envelope is 4–10°C, 55–62% relative humidity, in an opaque, oxygen-limited container. A refrigerator drawer with a calibrated humidity pack hits all three. A kitchen cupboard hits none.
Avoid freezing. Below 0°C the trichome structures become brittle and shatter on handling — you lose resin every time you cut a piece off. The flavour penalty is real and irreversible.
If you are buying hash worth grinding on an H-Masters, the storage investment is a $40 humidity pack and a $25 borosilicate jar. There is no excuse for treating premium material casually.
