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. Specs CVault 21 Liter at a glance Capacity 2.2 lbs (1 kg) Interior Dimensions 13.5" diameter x 10.25" deep (33 x 26 cm) Material 304 food-grade stainless steel Seal 1/4" food-grade silicone gasket Included Boveda 1x 320-gram, 62% RH Volume 21 liters Cleaning Dishwasher safe or warm soapy water Stackable Yes How to cure and store with your CVault 1 Place the Boveda pack in the lid Slide the included 320-gram Boveda 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 21 Liter holds up to 2.2 pounds. Avoid packing tightly, as airflow around the Boveda pack helps maintain even humidity throughout the large 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 Boveda every 2 to 4 months When the Boveda pack feels rigid and crunchy instead of flexible, swap it for a fresh one. The CVault itself lasts indefinitely.

Call or email us: 716-217-0353 / help@happyhydro.com Questions Frequently asked questions Can I use the CVault for curing, or is it only for long-term storage? 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 Boveda 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. How do I know when to replace the Boveda pack? A fresh Boveda feels soft and pliable. When the pack becomes stiff, rigid, or starts to feel like a thin brick, it's spent and should be replaced. In a well-sealed CVault, that typically takes 2 to 4 months depending on how often you open the container. We carry replacement Boveda packs separately. Will flower stored in a CVault smell through the container? 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. Is the 21 Liter big enough for a commercial harvest? The 21 Liter holds up to 2.2 pounds (1 kilo) of dried flower. That handles most multi-light home grows and smaller commercial harvests in a single container. If you regularly pull over 5 pounds, the 50 Liter is the next step up. For strain separation within a large harvest, pair a 21 Liter with several 2 or 4 Liter CVaults. Can I use a different humidity level Boveda instead of 62%? Yes. The lid holder accepts any 67-gram Boveda pack. 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. Do I need to buy anything else to use the CVault right away? No. The CVault ships with a Boveda pack already included. Open the box, place the Boveda in the lid, load your flower, and latch it closed. The only ongoing cost is replacement Boveda packs every few months. What if my CVault arrives damaged or defective?
