how to store cannabis flower

Keep cannabis flower in an airtight, opaque container and store it in a cool, dark place around 60–70°F with relative humidity near 58–62%. That combination slows moisture loss and protects the terpenes and cannabinoids that give flower its aroma and character. The whole routine takes about a minute, and it makes a noticeable difference the next time you open the jar.

Key Features of Good Flower Storage

• Airtight seal: a screw-top or gasket lid keeps outside air from drying the flower out and keeps the aroma in.
• Opaque or UV-blocking material: amber, frosted, or sleeved glass blocks the light that degrades cannabinoids.
• Humidity around 58–62%: the sweet spot where flower stays pliable without inviting mold.
• Right-sized jar: match container size to the amount you keep so there is little empty headspace.
• Cool, stable temperature: a dark cupboard beats a windowsill, a radiator, or the top of the fridge.
• Minimal handling: open the jar briefly, take what you need, and close it again.
• Separate containers: store different strains apart so strong aromas do not blend together.

Materials and Specs

Glass is the usual pick because it does not hold onto odors, does not carry a static charge that pulls trichomes off the flower, and cleans up easily between batches. Look for soda-lime or borosilicate jars with a tight-fitting lid and a capacity close to what you actually store — a quarter-ounce of flower sits comfortably in a small 2- to 4-ounce jar. If you use plastic, choose a thick, food-grade, opaque option and replace it when it starts to smell like the last strain. Two-way humidity control packs can be added to larger jars to hold the target range, and a simple hygrometer takes the guesswork out of it.

Shipping and Returns

Orders ship in plain, discreet outer packaging with the contents protected and sealed so nothing is crushed or exposed in transit. If a jar or accessory arrives damaged or is not what you expected, contact support for a replacement or return under the shop's standard policy.

How long does cannabis flower stay fresh in a jar?

Stored airtight, dark, and within the humidity range, most flower holds its best quality for about two to six months, with aroma fading gradually after that.

Can you store cannabis flower in the refrigerator?

It is usually not recommended. Fridges are cold and humid, and the repeated condensation each time you open the jar can encourage mold.

Should you use a humidity pack?

It helps for larger quantities or long-term storage, but it is optional for small amounts you will use within a few weeks.
