We've already talked about storing flowers on this blog, but a customer rightly pointed out that his resin didn't behave the same way at all in its jar. He was right: hash has its own rules, closer to those of a fatty food than a dried flower.
Why it's different from flowers
Resin and hash are concentrates, denser and often oilier than raw flower. They react differently to heat: rather than simply drying out, they soften and get sticky as soon as the temperature rises, which speeds up oxidation and terpene loss. Conversely, intense cold hardens the texture and can damage the structure of the concentrated trichomes inside.
The right temperature
Aim for a stable temperature between 15 and 20°C, away from sudden changes. In summer, when your home easily gets warmer than that, the fridge is a good temporary option – ideally between 0 and 10°C – to limit softening and keep the aromas longer.
The right wrapping
Forget plastic, which sticks to resin and degrades with prolonged contact. Baking paper is ideal: it doesn't stick, lets the resin breathe just enough without letting in too much air, and protects well against light if you then slip it into an opaque airtight box. A tinted glass jar also works very well for main storage.
Keep an eye on humidity
Too much humidity and resin becomes tacky, with a quickly rising risk of mould. Too dry, and it loses its suppleness and its aromas evaporate faster. Around 60% relative humidity is the right balance, achievable with a small humidity regulator if you want to be precise, though it's not essential for normal use.
What about the freezer?
It's not recommended for everyday use. The freezer mainly suits very dry, freeze-dried-type hash meant for very long-term storage – and even then, vacuum-sealed or perfectly airtight to avoid condensation when it thaws. For your usual consumption, a good jar at a stable room temperature is more than enough.
"I used to keep my resin in its original plastic bag, stuck in a drawer. Since I started wrapping it in baking paper and putting it in a jar, it stays soft much longer and the smell has hardly faded." – a customer of the shop
My straight advice
Always wrap your resin in baking paper before storing it in an opaque airtight container, keep it between 15 and 20°C all year round, and move it to the fridge in a summer heatwave. With these three simple habits, your resin keeps a texture and aroma close to fresh far longer than if you leave it in its original packaging. For ideal storage, check out our Terpseals jars.
