Cure and store a full pound in one airtight container

The CVault 8 Liter holds up to 1 pound of dried flower in a 304 food-grade stainless steel container that blocks 100% of light and seals airtight with a silicone gasket and latch system. Each unit ships with two 1 lb Vivi Fresh 62% RH packs that clip into the lid, giving you double the humidity regulation for a larger volume. Vivi is Boveda's new flower-care brand with the same patented 2-way formula. Some units may still ship with Boveda-branded packs during the changeover. If you are pulling a pound or more per harvest cycle, this is the container that fits without splitting your batch across multiple jars.

Vivi Fresh 2-Way Humidity 62% RH

The two included 1 lb Vivi Fresh packs clip into holders molded into the lid, maintaining 62% relative humidity automatically. They absorb excess moisture and release it back when conditions dry out.

Total Light Block

Stainless steel walls and lid eliminate UV and visible light exposure entirely. Glass jars, even amber ones, still transmit light that breaks down stored flower over time.

Engineered Latch Seal

The industrial latch compresses a thick 1/4" food-grade silicone gasket for a consistent airtight seal every time. No threading, no torque, no guessing if it's tight enough.

Writable Lid for Strain Labeling

Use any non-permanent marker to write directly on the lid surface. Wipe clean and relabel when you switch strains.

Stackable Design

Flat lids and uniform dimensions let you stack multiple CVaults vertically. Useful for growers curing several strains at once without eating up shelf space.

Dishwasher Safe, No Odor Retention

304 stainless steel doesn't absorb odors the way plastic does. Toss it in the dishwasher or hand-wash with warm soapy water between uses.

How to cure and store with your CVault

1

Place the Vivi Fresh packs in the lid

Slide both included 1 lb Vivi Fresh 62% RH packs into the holders molded into the underside of the lid. They click into place and stay put when you open and close the container.

2

Fill the CVault

Place your dried flower loosely into the container. The 8 Liter holds up to 1 pound. Avoid packing tightly, as airflow around both Vivi Fresh packs helps maintain even humidity throughout the full volume.

3

Latch it shut

Close the lid and flip the latch down. The silicone gasket compresses to form a complete airtight seal. No burping, no checking, no fussing.

4

Replace the packs about every 3 months

Vivi recommends fresh packs about every 3 months. Hardened corners or a few soft spots are normal, so replace a pack once it is rock solid all the way through. The CVault itself lasts indefinitely.

Frequently asked questions
Both. During the initial cure (first 2 to 4 weeks after drying), you can open the CVault daily to exchange air, then seal it back up. The Vivi Fresh packs regulate humidity the entire time, so you don't have to guess when to burp or how long. After curing is complete, the same container transitions straight into long-term storage.
A fresh pack feels soft and pliable. Hardened corners or a few soft spots are normal and the pack still works. Replace it when the whole pack is rock solid all the way through. Pack life typically runs 2 to 6 months depending on how airtight the container is and how often you open it, and Vivi recommends swapping about every 3 months. We carry replacement humidity packs separately.
No. The latched seal with silicone gasket prevents odor from escaping. The stainless steel body also does not absorb or retain smells between uses, so when you clean it out, it's truly clean with no residual aroma from previous contents.
The 8 Liter holds up to 1 pound of dried flower. That covers most home growers harvesting from a 4x4 or 5x5 tent. If you regularly pull over a pound, the 21 Liter (2.2 lbs) or 50 Liter (5+ lbs) handles commercial-scale batches. For smaller amounts or strain separation, the 2 Liter and 4 Liter sizes work well.
Yes. The lid holder takes the matching Vivi Fresh or Boveda pack size, and you can pick 58% or 62%. Some growers prefer 58% for a slightly drier cure. The 62% packs included with the CVault are the most common choice for preserving weight and aroma during storage.
No. The CVault ships with two Vivi Fresh packs already included. Open the box, place the packs in the lid, load your flower, and latch it closed. The only ongoing cost is replacement packs about every 3 months.
