Proper humidity is the difference between enjoying fresh, flavorful flower, and coughing your way through harsh, quick-burning bud.

That glass jar or baggie might be your go-to for protecting your flower, but are you helping it reach and maintain its full potential? A little too near a sunny window, too long in a hot car, and BAM, there goes your potency. Lid not screw on just right? Say hello to staleness and harsh hits.
But you can avoid this reality by creating your own! Inside your stash container, anyway. To get the most out of what’s in your jar, you need to take measures to keep your flower fresh.
Three Easy Ways to Keep Cannabis Flower Fresh:
- Control the temperature
- Avoid exposure to light
- Control the humidity
Light and heat break down the active compounds, so buds should always be stored in a dark place, ideally around 60-68 degrees Fahrenheit.
Medical or recreational, professional or home-grown—humidity control is crucial. Without it, you could develop mold (eek!) or turn stale quickly and lose potency to the ravages of evaporation.
How Long Does Flower Stay Fresh?
Generally speaking, it’s a good idea to consume purchased flower within about 6 months. However, you can extend your bud’s shelf life by storing it with Boveda 2-way humidity control packs in air-tight cannabis containers.
How Does Humidity Affect My Cannabis?
When most people think of humidity, they think of the weather. Hot and sticky climates like Florida have high humidity percentages, while dry deserts like Nevada have low humidity. Humidity also has a huge impact on unprotected buds.
Humidity affects flower in a few ways. If the environment is mucky, buds get overly moist, leading to mold and other nasty pathogens you shouldn’t inhale. On the other hand, arid conditions suck out moisture, leading to quick-burning staleness.
That’s not all the damage humidity can do. Terpenes—those delicious compounds responsible for how your flower smells and tastes—are extremely susceptible to humidity. Which is to say they don’t like it. At all. If the humidity starts dipping just a little bit too low, terps begin to evaporate, even inside an airtight container.
Because when it comes to freshness, a proper flower storage container is only part of the equation.
What is the Correct Humidity to Keep Cannabis Fresh?
The humidity sweet spot for storing flower is between 55% and 65%. This guideline was established by ASTM International, a respected trade organization responsible for setting the rules and regulations for various industries.
How can I control the humidity in my stash?

How Does a Humidity Control Pack Work to Keep Cannabis Fresh?
Boveda humidity packs for weed may absorb moisture or release it as water vapor, depending on the conditions inside your airtight container. Boveda creates a microscopic shield of water around the trichomes to prevent terpene evaporation, keeping your fresh, flavorful, and potent.
