The Best Weed Jars to Keep Your Stash Fresh

Just like all agricultural commodities, cannabis requires proper storage to be at its best. Improper storage can affect the quality of cannabis in several ways, including the loss of potency and flavor. 

Luckily, products to help keep cannabis fresh, safe, flavorful, and potent are available. Jars for holding cannabis, colloquially known as weed jars, are a popular option. 

The 5 Best Weed Jars or Containers

5. Herb Guard 1oz Stash Jar

Herb Guard's range of airtight, UV-filtering, and odor-proof jars will effectively disguise the scent of even the most aromatic buds.

Its features include airtight lids, ultraviolet light filtering, varying size capacities up to two ounces, and protective locking pouches. These weed container products also include jar labels and a disposable humidity pack.

A purpose-built weed jar can help consumers adhere to the best practices of cannabis storage. But if it’s too late and you already have bud that is beyond its prime, there are still things you can do with old weed.

The Importance of Proper Weed Storage

Although weed doesn’t expire like perishable foods, proper cannabis storage is important for several reasons, including maintaining the safety of the herb. A good quality weed jar will help preserve potency, flavor, and freshness while keeping the cannabis safe from spoilage.

Maintaining Cannabinoid Potency

Cannabinoids such as THC and CBD can degrade with exposure to time, light, heat, oxygen, and sunlight. Because of this, improperly stored cannabis will lose its potency and be less effective over time.

Storing cannabis in a cool, dark place with minimal moisture will help preserve potency. Experts recommend storing dried cannabis products at 1-5 °C (31-43 °F), but some experiments found that samples stored at 120 °F for up to 30 days can maintain their quality without impacting the chemical profiles.¹

Preserving Aroma and Flavor

Cannabis stored in less-than-optimal conditions can quickly lose aroma and flavor. The terpenes and other compounds responsible for cannabis's distinct yet varied flavors and aromas are often volatile. Because of this, bud not stored in a tightly sealed, airtight container will lose some of its aroma and flavor. The best weed jars are light-proof and airtight.

Keeping Cannabis Safe

Cannabis not properly dried before packaging or stored in damp conditions can develop mold, making it unsafe to consume. Proper storage in containers that do not let moisture in will keep cannabis safe and fresh.² 

Additionally, some weed jars will have an integrated humidity control pack that keeps cannabis at the proper moisture level for safety and freshness. Humidity control packs are also sold separately if the jar has no integrated option.

Keeping Kids and Pets Safe

Consumers should be sure to keep their stash away from children and animals. A child-proof weed jar can add an extra layer of protection and help prevent accidental consumption.

What to Look for in a Weed Container

Much of the cannabis purchased at dispensaries, particularly as eighths, is sold in resealable glass jars. Many consumers may find these jars perfectly adequate for their needs when kept in a cool, dark place.

Those considering purchasing a purpose-made weed jar should keep several factors in mind.

Container Size

Consider how much cannabis you are likely to keep on hand when deciding which weed jar to buy. Some hold up to an ounce of bud, with larger and even smaller options also available. Those who like to keep more than one strain of cannabis on hand might want a separate weed jar for each variety.

Container Material

Weed jars should be made of a material impervious to air and moisture to preserve freshness and prevent spoilage due to mold. Ceramic, glass, stainless steel, or natural wood containers are all suitable options. Plastic bags and containers should be avoided because they can hold a static charge that attracts trichomes away from buds.

Humidity Control

High humidity levels may result in moisture exposure, which can prompt mold growth, whereas low humidity will dry out bud. Weed storage containers with humidity packs and specialty humidors can preserve flower at an ideal relative humidity of 59-63%. 

Price

An acceptable quality cannabis storage container will cost at least $20, with top-of-the-range products costing up to $200. However, price doesn’t always reflect quality, so shop wisely and always research a brand beforehand.

Smell-Proof Weed Containers

Some containers are designed specifically to be smell-proof, keeping your stash discreet from prying nostrils. Patients and consumers who carry cannabis away from home might want to consider a jar to keep themselves safe. In some states, the smell of cannabis alone can be considered probable cause to search a vehicle.

Generally, all airtight containers are smell-proof and provide adequate aroma protection.

Those who take cannabis on the go might also want to invest in a smell-proof bag. These products, designed as backpacks or other totes, are often designed to include activated carbon to help absorb pungent cannabis odors.
