How to Store Cannabis Flower: The Ultimate Freshness Guide

Why Proper Storage Is the Secret to a Perfect Session

You just brought home a beautiful, aromatic ounce of Kemp Cannabis premium flower. Now what? Toss it in a plastic baggie? Absolutely not! The first and most critical step after a purchase is knowing how to store cannabis flower correctly.

If cannabis is improperly stored, it doesn’t just dry out; it loses its terpenes (those flavorful, aromatic oils) and, crucially, its potency. Over time, THC converts to CBN, a cannabinoid often associated with more sedative effects. Learning how to store cannabis flower isn’t just about tidiness—it’s about preserving your investment and guaranteeing a consistent experience. This guide covers everything you need to keep your stash potent and delicious.

The Four Horsemen of Cannabis Degradation

To fight back against a stale stash, you need to understand the four elements that are actively working to break down your flower:

1. Light (UV Rays are the Enemy)

Just like strong sunlight fades fabrics, UV rays break down cannabinoids (like THC) and terpenes.

Kemp’s Rule: Always use opaque containers. This is why you rarely see flower sold in clear jars—it’s a recipe for rapid quality loss.

2. Air (Oxidation and Dryness)

Too much air causes oxidation, degrading cannabinoids and accelerating the conversion of THC to CBN. Too little air, however, can promote mold growth, especially if the humidity is too high.

  • The Container Check: Use the smallest container possible to match your stash size, minimizing the trapped air.

3. Temperature (Keep it Cool, But Not Too Cold)

High heat can evaporate volatile terpenes, stripping your flower of its flavor and aroma.

  • The Spot Check: Keep your stash below 70°F (21°C), ideally in a cool, dark place. Avoid storing near appliances, vents, or sunny windows.

4. Humidity (The Moisture Sweet Spot)

This is the most critical and often overlooked factor. The ideal relative humidity (RH) for cannabis storage is 58% to 62%. Too dry, and it crumbles and burns fast; too wet, and mold is a serious risk.

Choosing the Best Cannabis Storage Container

The container is your first line of defense. Ditch the plastic baggies and cheap containers—they can actually leech terpenes!

Container TypeProsCons
Airtight Glass Jars (Best)Inert material (won’t affect flavor); excellent seal; affordable.Breaks easily; must be opaque or kept in the dark.
Canning JarsExcellent seal (like mason jars).Usually clear, requiring them to be stored inside a drawer or box.
Metal/Aluminum TinsDurable, light-proof, travel-friendly.Can develop a metallic taste over very long periods.
Wooden BoxesEsthetically pleasing, discreet.Wood is porous and offers poor air sealing; often not airtight.

Do You Need a Humidity Pack? (The Answer is Yes)

For long-term storage, a specialized two-way humidity control packet (often found in 58% or 62% RH) is a game-changer. These packets actively add or remove moisture to keep your flower in that ideal 58-62% range, protecting those precious terpenes.

Keep your Kemp flower at room temperature in a cool, dark, airtight container with a humidity pack, and you’ll enjoy peak freshness every time.
