Flower loses terpenes and potency fast when it's stored wrong. Here's how to keep your stash tasting the way it did when you bought it.

The enemies of fresh flower

Light — degrades cannabinoids
Heat — dries buds and burns off terpenes
Air — oxidation
Humidity swings — too dry crumbles, too wet molds

The right setup

Airtight glass jar, kept in a cool dark cabinet, with a two-way humidity pack (58–62% RH) tossed in. That's it. Skip the plastic baggies and the fridge.

How long it lasts

Stored properly, flower stays great for 6+ months. Pre-rolls dry out faster — smoke those within a few weeks of opening.
