Quick answer
Store flower in a clean, airtight container in a cool, dark place with a stable environment. Heat, direct sunlight, excess air exposure, and uncontrolled moisture can all affect quality over time.
Choose the right container
A well-sealed glass container is a common option because it limits air exchange and does not readily hold odours. Keep it clean and use a size that does not leave excessive empty space. Avoid containers that have held food residue or strong fragrances.
Control light, heat and humidity
Keep containers away from windows, radiators, cars, and other hot places. Excess moisture can encourage mould, while very dry conditions can make flower brittle. Humidity-control packs are designed for certain storage uses, but follow the maker’s instructions and do not treat them as a way to rescue mouldy material.
Can dry flower be revived?
A humidity-control product may help moderate moisture in some circumstances, but it cannot restore lost aroma compounds or reverse degradation. Do not add fruit peels, bread, or other food to a container; they can introduce moisture unevenly and may encourage microbial growth.
Signs to avoid
Do not use flower with visible fuzzy growth, unusual dampness, or a musty smell. Do not scrape off suspected mould and assume the rest is safe. When in doubt, discard it safely.
Keep it secure
Use child-resistant storage where possible, keep products clearly labelled, and store them separately from food. Follow local laws and never leave cannabis where children or pets can reach it.
