How To Store Cannabis So It Does Not Dry Out

Nearly every complaint about harsh, dusty, disappointing flower comes down to storage rather than the bud itself. Getting how to store cannabis right costs almost nothing and makes a jar last months instead of weeks. Here is the whole of it.

Glass, not plastic

A sealed glass jar is the entire answer for most people. Plastic bags carry a static charge that strips the trichomes off the outside of the flower — that is the fine frosty layer you paid for, ending up stuck to the bag. Plastic also breathes, so moisture escapes steadily.

Any small glass jar with a rubber-sealed lid works. Fill it about three-quarters full: enough air to avoid crushing the flower, not so much that the jar dries it out.

Keep it dark

Light is the fastest way to degrade cannabis. UV breaks the plant down, which is why a jar left on a sunny windowsill is noticeably worse in a fortnight. A cupboard or drawer is fine — you do not need anything special, just not the light.

Stable temperature beats cold

Room temperature in a cupboard is ideal. Do not put it in the fridge or freezer: the swings in temperature cause condensation each time you take it out, and moisture is what starts mould. Cold also makes trichomes brittle, so they snap off when you handle the bud.

Humidity is the one people get wrong

Too dry and it turns to dust and smokes harshly. Too damp and you risk mould, which is not worth gambling on. Somewhere around 55 to 62 percent relative humidity is the range to aim for, and a small two-way humidity pack in the jar holds it there without any thought.

A quick test: bud at the right humidity springs back slightly when you squeeze it. If it crumbles instantly, it is too dry. If it feels spongy or smells of damp, do not smoke it.

How to store cannabis day to day

• Grind as you go, not in advance. Ground flower dries out several times faster — see our grinder and gear guide.
• Keep strains in separate jars. Aromas migrate and everything ends up smelling the same.
• Do not store it in the grinder. It is not airtight and it is usually in a pocket or a bag.
• Open the jar briefly, not often. Every opening swaps the air inside.

Does the grade change how you store it?

Not really — the rules are the same across the shelf. It just stings more when it happens to the expensive stuff. Dense indoor holds moisture a little longer than airy outdoor, and greenhouse sits in between, but glass and darkness serve all three. If you are choosing between tiers in the first place, our indoor vs outdoor guide lays out the differences.

We do not stock jars — any airtight glass jar from the kitchen shelf does the job, and a dark cupboard does the rest. What we do stock is the gear you use around it: grinders, papers and cones are on the consumables shelf.

Herb Shack runs a loyalty membership: it is free to join, you need to be 18 or over to register, and registering is what unlocks the THC side of the shelf. Members earn a point for every R1 spent and put those points towards money off future orders.
