What effect does placing marijuana in a freezer have on it? Does it keep it fresh? Will it turn purple? — Genie
Some people will tell you to freeze your cannabis or to store it in the fridge to “keep it fresh”. Of course, marijuana can be frozen but should it? The long and short answer is no.
Freezing your buds will not turn them purple or keep them fresh. They can turn purple from either their genetics or cold temperatures as they approach harvest but they won’t change color drastically after harvest. Green buds will typically get a little less bright green as they cure but none will turn purple after they’re chopped down.
I don’t ever recommend placing marijuana in a freezer or refrigerator. Freezing temperatures, fluctuating humidity and bright light all degrade THC and other cannabiniods. This will ultimately result in less flavor and potency.
The best place for storing pot is in a cool, dark place in a dark-colored or opaque sealed glass jar. Also, marijuana should really be consumed within a year or so of when it’s grown. Some connoisseurs have longer cured stuff that’s several years old, and it does take on interesting qualities as it ages, but ultimately, it eventually degrades. For every expertly long-cured, three-year-old bud I’ve smoked that burned perfectly and preserved the terpene profile, I’ve smoked far more old pot that’s simply past it’s prime. Besides, you can always grow more!
