CVault 4 Liter Humidity Curing Storage Container, 9" x 5.5"

Humidity-Controlled Curing and Storage – CVault 4

The CVault 4 Liter Humidity Curing Storage Container holds 1/2 lb with two-way humidity control maintained by an included Boveda humidity pack. The Boveda pack attaches to the inside of the lid, positioning it directly above the stored material where humidity distribution is most effective.

The lid features a 1/4-inch silicone seal for an airtight closure, a dedicated Boveda pack holder, a writable surface for labeling, and industrial-grade latches that lock consistently. The 4L CVault is built from food-grade stainless steel and stacks with other CVaults for compact multi-variety storage. Dimensions: 9 x 5.5 inches.

Key Features & Benefits

• Airtight Silicone Seal — 1/4-inch-wide silicone seal provides a consistent airtight closure every time.
• Industrial Engineered Latch — Heavy-duty latches lock the lid shut for a reliable, consistent seal.
• Boveda Humidity Pack Holder — Inside the lid, a dedicated holder positions the Boveda pack for optimum humidity distribution.
• Writable Lid Surface — The lid surface accepts a non-permanent marker so you can label each vault as contents change.
• Stackable Design — CVaults stack on top of one another for space-efficient multi-variety storage.
• Food-Grade Stainless Steel — Built from food-grade stainless steel throughout for safe, long-term dry storage.

Who Should Use This Container

CVault is designed for cultivators, processors, and retailers who need reliable humidity-controlled storage for cured flower. The stainless steel construction, airtight seal, and Boveda system are appropriate for both commercial storage and personal use. The stackable design makes CVaults practical for operations storing multiple varieties simultaneously.

Two-Way Humidity Control and the Boveda System

CVault containers use Boveda humidity packs to maintain a precise relative humidity level inside the sealed vault. Boveda packs work two ways: releasing moisture when humidity drops below the target level, and absorbing excess moisture when humidity rises above it. This two-way control maintains a consistent environment throughout the curing and storage period — unlike one-way desiccants that only remove moisture. The 62% Boveda packs included with smaller CVaults are chosen for post-harvest curing and preservation.

Frequently Asked Questions

What is included with the CVault?

The 4L CVault includes the container and one 60g 62% Boveda humidity pack pre-positioned in the lid holder.

What humidity level does the included Boveda pack maintain?

The included Boveda pack is 62% RH, which is widely used for curing and preserving dried flower.

Can I write on the lid?

Yes. The top of the lid accepts a non-permanent marker so you can label the contents and relabel as the vault's contents change.

Is the CVault stackable?

Yes. CVaults are designed to stack on top of one another, allowing compact storage of multiple containers and varieties.

When should I replace the Boveda pack?

Replace the Boveda pack when it becomes fully hardened (no longer flexible), indicating it has reached saturation and can no longer regulate humidity effectively.
