CVault Bud Storage 4 Liter — Happy Hydro

Store a half-pound harvest in airtight stainless steel

The CVault 4 Liter holds up to 8 ounces (half a 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 of the four units ships with one 1 lb Vivi Fresh 62% RH pack that clips into the lid (four packs total), so humidity regulation starts immediately with no guesswork. Vivi is Boveda's new flower-care brand with the same patented 2-way formula, and some units may still ship with a Boveda-branded pack during the changeover. This is the most popular size for home growers pulling moderate harvests from a single tent.

Vivi Fresh 2-Way Humidity 62% RH

The included 1 lb Vivi Fresh pack clips into a holder molded into the lid, maintaining 62% relative humidity automatically. It absorbs excess moisture and releases 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 pack in the lid

Slide the included 1 lb Vivi Fresh 62% RH pack into the holder molded into the underside of the lid. It clicks into place and stays put when you open and close the container.

2

Fill the CVault

Place your dried flower loosely into the container. The 4 Liter holds up to 8 ounces. Avoid packing tightly, as airflow around the Vivi Fresh pack helps maintain even humidity.

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 Vivi Fresh pack about every 3 months

Vivi recommends a fresh pack about every 3 months. Hardened corners or a few soft spots are normal. Replace it when the whole pack is rock solid all the way through. The CVault itself lasts indefinitely.

Not sure which size to pick? The 4 Liter is the sweet spot for most home growers harvesting a half pound or less per run. If you grow multiple strains, consider buying singles of each size. Call or email us: 716-217-0353 / help@happyhydro.com
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 pack regulates 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.
Vivi recommends swapping in a fresh pack about every 3 months. A pack with hardened corners or a few soft spots still works. Replace it when the whole pack is rock solid all the way through. Depending on how airtight the container is and how often you open it, a pack typically lasts 2 to 6 months.
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 4 Liter holds up to 8 ounces of dried flower, which is a half pound. For most home growers harvesting two to four plants, that covers a single run. If you regularly pull over a pound, look at the 8 Liter (1 lb) or 21 Liter (2.2 lbs). If you want to separate multiple strains, individual 2 Liter CVaults or the 2 Liter 4-Pack work well for that.
Yes. The lid holder takes the matching 1 lb Vivi Fresh or Boveda pack size, and you can pick 58% or 62%. Some growers prefer 58% for a slightly drier cure. The 62% pack included with the CVault is the most common choice for preserving weight and aroma during storage.
No. The CVault ships with a Vivi Fresh pack already included. Open the box, place the pack in the lid, load your flower, and latch it closed. The only ongoing cost is a replacement Vivi Fresh pack about every 3 months.
