CVault Storage Container: Stainless Steel Humidity-Controlled Stash
The CVault storage container is a food-grade stainless steel vessel that keeps cannabis fresh, potent, and properly humidified for months. Unlike glass jars that let light degrade your terpenes and cannabinoids, the CVault blocks 100% of light while maintaining a sealed 62% relative humidity environment — the sweet spot for long-term herb storage and curing. Available in eight sizes from a pocket-friendly 0.175L up to a serious 50L bulk container, there's a CVault for every stash size from personal to commercial harvest.
Which CVault Size Do You Need?
The personal sizes (0.175L, 0.5L, 0.95L) are your everyday carry and countertop stash jars. The commercial sizes (2L upwards) are built for growers who need proper curing and bulk storage. Here's the full breakdown:
| Size | Category | Diameter | Height | Included Humidipak |
|---|---|---|---|---|
| 0.175L | Personal | 8 cm | 4 cm | 1x 8g Humidipak 62% |
| 0.5L | Personal | 10 cm | 6.8 cm | 1x 8g Humidipak 62% |
| 0.95L | Personal | 12 cm | 8.5 cm | 2x 8g Humidipak 62% |
| 2L | Commercial | 20 cm | 10 cm | 1x 67g Humidipak 62% |
| 4L | Commercial | 23 cm | 14 cm | 1x 67g Humidipak 62% |
| 8L | Commercial | 26 cm | 18 cm | 2x 67g Humidipak 62% |
| 21L | Commercial | 33 cm | 26 cm | 1x 320g Humidipak 62% |
| 50L | Commercial | - | - | Contact for details |
Our pick for most personal users: the 0.95L. It holds a comfortable amount without wasting space, and the two included Humidipaks give you solid humidity coverage. If you're curing a harvest, jump straight to the 21L — it handles large yields and the 320g Humidipak keeps the environment stable across that bigger volume.
Why the CVault Beats Glass Jars for Cannabis Storage
We've sold mason jars, UV glass, silicone containers, and everything in between since 1999. The CVault is the storage solution we'd actually put our own stash in, and here's why.
Light is the silent killer of good cannabis. Even amber UV glass lets some wavelengths through over time, slowly breaking down THC into CBN and degrading the terpene profile that gives your strain its character. Stainless steel blocks every photon. Zero light penetration, full stop. Your herb stays as close to harvest condition as physics allows.
Then there's the humidity problem. Too dry and your trichomes turn to dust the moment you grind — harsh smoke, lost potency, and that papery taste nobody enjoys. Too humid and you're inviting mould, which means binning the lot. The CVault solves this with the included Boveda-style Humidipak, a two-way humidity control system that both absorbs excess moisture and releases it when the air inside gets too dry. It holds a steady 62% relative humidity, which is the figure most growers and connoisseurs agree is the target for stored cannabis.
The honest limitation: the CVault is heavier than a glass jar and costs more upfront. You can feel the weight of the stainless steel when you pick it up — it's a solid, chunky piece of kit, not something you'd toss in a backpack without noticing. The 0.175L is manageable for travel, but the commercial sizes are strictly stay-at-home storage. If portability matters more than preservation, a small UV glass jar might suit you better. But for keeping your herb in peak condition? The CVault is the best stash container we carry.

The included Humidipak won't last forever — they typically need replacing every 2-4 months. Grab a replacement Humidipak in the right gram size for your CVault so you're never caught short. If you're storing freshly harvested cannabis, a digital hygrometer is worth pairing with your CVault to confirm your humidity levels during the first few days of curing.
How to Use the CVault Storage Container
- Unbox your CVault and remove the included Humidipak(s) from their sealed wrapper. Place the Humidipak inside the lid — there's a built-in holder designed to cradle it above your herb.
- Place your dried cannabis (or other herbs) inside the CVault. Don't pack it too tightly — leave some air space so the humidity can circulate evenly throughout the container.
- Close the lid firmly and engage all the latches until you feel the silicone seal compress. The seal should be snug all the way round with no gaps.
- Store the CVault in a cool, dark place. A cupboard or drawer works well. The steel blocks light regardless, but keeping ambient temperature stable (around 15-21°C) gives the best long-term results.
- If using the CVault as a curing jar, open the lid once or twice daily for the first 1-2 weeks to "burp" the container and let fresh air exchange. Give the contents a gentle shake to redistribute the buds. After 2-3 weeks, reduce burping to every few days until curing is complete (typically 4-8 weeks total).
- Check the Humidipak every couple of months. When it feels stiff and crunchy rather than pliable, it's spent — swap it for a fresh one in the correct gram size for your CVault.
