CVault 4L Curing Storage Container Holds Half a Pound
Four liters, 9" across and 5.5" deep, in 18/10 food-grade stainless steel sealed by a ¼" silicone gasket. Roughly eight ounces of dry plant material, held in complete darkness behind an airtight latch. It is the step up from personal sizes without moving into commercial footprints. The 2 L below it holds about three ounces and the 8 L above it holds a pound. Half a pound is the quantity that outgrows a jar but does not need a cure room. Steel does two things glass cannot: it blocks light completely, and it does not break when a shelf gets crowded. The gasket and latch are what make it airtight rather than merely closed.
A Half Pound Stainless Steel Curing Vault With Boveda Included
The included 67 g 62% RH Boveda is rated to a full pound. At eight ounces it runs with headroom and holds RH steady longer between swaps. That margin is the practical reason to size the pack above the load rather than exactly to it. Lid marks with non-permanent marker and the container stacks, so several strains can run in parallel without confusion. One trade-off worth naming: you cannot check contents without opening it, unlike glass. Every opening costs a little of the equilibrium the pack has built. In practice that means checking less often, which is usually better for the material anyway. Replacement runs on roughly a three-month cycle. Replacement 67 g packs are stocked as singles, in a 6 pack and by the case, which is the only recurring cost for curing here.
Key Features
- 18/10 Food-Grade Stainless Steel: Holds no odor and takes commercial handling without denting like thin-wall tins.
- Completely Light-Tight Body: Blocks the UV that fades and degrades material sitting in clear glass.
- ¼" Silicone Gasket Seal: Pulls flat under the latch so ambient air does not creep in between openings.
- Lid-Mounted Boveda Holder: Keeps the pack off the contents and out of the way when scooping.
- 4 L Capacity: Sized at about 8 oz of dry plant material, under a pack rated for a full pound.
- Writable Lid Surface: Non-permanent marker wipes off, so one container follows several batches.
- Stackable Body: Vertical storage keeps a cure room organized without extra shelving.
- Airtight Locking Latch: Seals aroma in rather than letting it bleed into the room over weeks.

How Much Does a CVault 4L Hold?
About eight ounces of dry plant material. The 2 L sits near three ounces and the 8 L steps up to a full pound.
Is One 67 g Boveda Enough for a 4L?
Yes, comfortably. A 67 g pack is rated to a pound, so at eight ounces it has spare capacity and holds RH longer.
How Often Should the Boveda Be Replaced?
Every three months as a rule, with typical in-use life running two to four months depending on how often the vault is opened.
Can a CVault Replace Glass Jars for Curing?
For long holds it improves on them — steel blocks the UV that degrades material in glass, and the Boveda holder removes the burping routine.
