Fresh-Port™ Technology for Inert Noble Gas Insertion

In addition to creating an airtight seal, the Fresh-Port™ Large Mouth Mason Jar Lid includes the Fresh-Port™ Valve to introduce noble gases, like Argon, to displace oxygen and maintain freshness.

Shop our Airgone™ Argon Canister to further prevent THC degradation through the oxidation process.

Built-in Strap for Boveda Humidity Packets

In addition to the prevention of oxidation, controlling humidity is essential for avoiding THC degradation or preserving any stored goods. The importance of humidity control inspired us to include a built-in strap for the underside of the lid to hold your humidity pack.

The Fresh-Port™ is a great product by itself but is most effective when used with the AirGone™ Argon Gas Can and a Boveda® pack. 

Store your bud in the mason jar, place the Fresh-Port™ Mason Jar Wide Mouth Lid on, Insert Airgone™ Argon Gas into the Fresh-Port™ valve and apply a 2-second flush (repeat every time you open your container).

C02 buildup is something you don’t have to worry about with Fresh-Port™ technology. Each Fresh-Port™ lid features a degassing valve that burps your jar of naturally occurring C02.

The Airgone™ Argon Gas Canister will last around 75 2-second flushes.

It depends. They can last anywhere from a month to 4 months, depending on how often you reintroduce a new strain to your stash jar. When adding a new strain, the Boveda® pack will have to work extra to control the humidity inside your container.

Yes! If you want to store other dry goods or are fermenting, we recommend using the Fresh-Port™ Large Mouth Mason Jar Lid with the AirGone™ Argon Gas Can.

We recommend only using the Boveda® pack we offer when storing cannabis.
