Maximum UV protection for long-term curing and storage, no jars, no burping, no maintenance
Grove Bags Opaque Pouches block 100% of visible light, giving your dried herbs the best possible protection during curing and extended storage. The bag's engineered 6-layer film actively regulates humidity to 58-62% RH, diffuses unwanted gases, and controls odor without any humidity packs, jar burping, or daily monitoring. Available in 10 sizes from 1/8oz to 10lb, the opaque pouches are the most popular choice for dispensaries, commercial operations, and home growers who prioritize preservation over visibility.
No window means zero light penetration. UV and visible light degrade quality over time, and opaque pouches eliminate that variable entirely. This is the primary reason dispensaries and commercial packers choose opaque over windowed.
58-62% RH, No Packs Needed
The engineered film regulates humidity passively once activated by your product's own moisture. No Boveda packs, no hydrometers, no maintenance.
Oxygen Diffusion, No Burping
The film's calibrated permeability lets unwanted gases escape while maintaining the internal atmosphere. No daily burping, no opening and resealing. Seal it and forget it.
Odor Containment
Six-layer film construction locks odor inside the bag. Sealed opaque pouches are discreet for transport, storage, and retail display.
Anti-Static Film
Static buildup damages trichomes and pulls them off the flower surface. The anti-static layer in the film prevents this, preserving the surface integrity of your product.
Widest Size Range in the Lineup 10 sizes
1/8oz through 10lb. The opaque pouches are the only Grove Bags variant available in every size, including the 2lb, 5lb, and 10lb commercial sizes that windowed bags don't come in.

How to cure with opaque pouches
1
Dry to 10-12% moisture
Use the snap test: stems should snap cleanly but not crumble apart completely. A wood moisture meter gives a precise reading if you want to dial it in exactly.
2
Fill to 75%, do NOT squeeze out air
Leave 25% headspace in the bag. This airspace is required for the film to regulate properly. Do not press or vacuum the air out.
3
Seal the bag
Heat sealing gives the best long-term results, but the zipper works fine for storage under 6 months. For commercial operations, a heat sealer is worth the investment.
4
Store in a cool, dark place
No burping needed. The film handles gas exchange on its own. With opaque pouches, any storage location works since the bag already blocks all light.
Need a window? The Windowed Pouches use the same film in sizes 1/8oz to 1lb.

Questions
Frequently asked questions
That's the trade-off for maximum UV protection: you trade visibility for preservation. The film is doing its job whether you can see the contents or not. If you need to inspect your product during curing, use the Windowed Pouches for a portion of your batch while storing the bulk in opaque. Many growers keep one windowed bag as a "check bag" and store the rest in opaque for the best of both worlds.
No. The engineered film handles gas exchange passively. Unwanted gases diffuse out through the film's layers while maintaining the internal humidity at 58-62%. This is the main advantage over mason jars: seal once, store, done. No daily opening, no schedule, no guesswork.
No. The film regulates humidity on its own using moisture from your product. Adding a humidity pack actually interferes with the film's ability to calibrate properly. Dry to 10-12% moisture content before bagging, fill to 75%, seal, and the film takes over.
Yes. The bags are durable and designed for multiple uses. The UV protection and anti-static properties do diminish gradually over time, but humidity control and odor containment remain effective through several cycles. Store empty bags in a dark place between uses. If you heat-sealed the first time, trim the sealed edge and reseal on the next use.
Heat sealing gives the tightest possible closure and is recommended for storage over 6 months or any commercial packaging. The zipper works fine for personal use and shorter storage periods. The zipper is designed for sealing and long-term storage, not daily open and close. If you need frequent access, the Glassless Grove Bags have a 5-track zipper built for that.
At commercial volumes, UV protection and privacy matter more than visibility. Growers storing pounds at a time are past the "checking on it" stage and need maximum preservation. These larger sizes are designed for backend storage before portioning into smaller retail bags.
