Weed Storage

High-Quality Weed Storage by Cannador®


55% - 62% RH


Why? Studies have empirically shown that cannabis will retain a higher terpene and cannabinoid content when this range of moisture is present for a prolonged period of time. This translates to a more robust flavor and a great high.

Previous studies like “The Stability of Cannabis and its Preparations on Storage,” conducted by J.W. Fairbairn, J.A. Liebmann, and M.G. Rowan from the Pharmacology Department in the School of Pharmacy, University of London in 1975 found that that the best long-term weed storage method required keeping cannabis at room temperature in a dark and sealed container. They stored cannabis and resin in varying conditions for two years and observed changes in THC potency.

Use an airtight mason jar and add Boveda® packs and keep it in a dark cupboard away from any light.

Whether you use glass, metal or wood, make sure it’s airtight and keep the relative humidity (RH) between 55% to 62%.

Use an airtight box, like the Cannador® or your makeshift stashbox, so long as it’s airtight, and add a humidity element such as VaporBeads or Boveda® packs. Make sure to separate strains so they’re not touching each other. Some strains have volatile aromatic compounds that can affect each others’ tastes if they rub up against each other.

Keep weed in a freezer. This will make the trichomes dry and brittle, and will break off, leaving your weed tasteless.

Keep weed in tin cans. These tin cans let in too much oxygen, which degrades THC over time. Furthermore, without a humidity element, your buds will dry out.

Keep weed in sandwich bags. The plastic has static that will pull off the trichomes, which contain the cannabinoids.

Add fruit to your storage container with the intention of adding moisture. This will create too high of an RH and will mold your bud.



There are many weed storage products available today, and more continue to hit the market each year. One of the most popular methods is using a Mason Jar. It’s both cheap and simple to use. One thing it does not do, however, is safeguard against UV light, so if you’re using this method, it’s best to keep it in a dark cupboard.

Over the years, we met with many large-scale cannabis growers to learn about their weed storage methods and practices. Many of these growers supply well-known dispensaries, so we were certain that we’d see hospital-grade storage equipment that would blow us away. After all, cannabis is a medicine that took serious capital and time to harvest, so wouldn’t they want to protect and safeguard their investment? Ironically, the most common method among growers is storing weed in large plastic garbage bags, then putting them inside a Rubbermaid® tub. Occasionally we would hear about growers inserting oxygen absorption packets, like those found in various food and textile products. Dispensaries also use basic methods like using Mason Jars and Tupperware® or Rubbermaid® bins. Many dispensaries are out of inventory by the weekend, so again, storage isn’t exactly pertinent to their process, which is why buds are extremely dry when you get them. Some states mandate that the cannabis be sold in airtight, sealed packages that already have been measured and weighed. Some dispensaries that are subject to these laws inject small amounts of nitrogen into the package prior to sealing. Just like we do with packaging food products like potato chips and cereal, nitrogen disperses oxygen, so no bacteria can grow.The weed storage methods that we use at Cannador® incorporate humidification to help mitigate evaporative loss from the trichomes (aka drying out).

The best part about adding humidification is that you can revive dry weed. It usually takes two to three days to revive dry weed in a Cannador® before you can begin noticing a difference in the bud’s texture and weight. It will become squishier, yet you still want the buds to have a slight firmness. The benefits are a more smooth finish when smoking, a more robust taste, and a well-rounded high.
