Grove Bags Smell Proof Bags — Passive Humidity Control Storage for the Growing Cycle
Best for: Growers who want to cure and store plant material without manual monitoring, hassle, or spending a fortune on jars and humidity packs
Our thoughts
These are genuinely clever. TerpLoc technology handles the hard work for you — maintains the perfect humidity, kills odours, and needs zero burping. If you're tired of babysitting mason jars or replacing humidity packs every other week, these are worth the shift. Proper bit of kit at a price that makes sense.
Grove Bags are multi-layer smell proof storage bags engineered with patented TerpLoc® technology to handle the curing process automatically. Unlike traditional mason jars, which require regular opening and "burping" to manage humidity, Grove Bags passively maintain the ideal moisture environment between 58% and 62% — the sweet spot for curing — with zero intervention. Six-layer barrier film protects against UV light, locks in aroma, manages oxygen levels, and prevents mould growth. Fill, seal, and leave it. That's the entire system.
How it compares
Grove Bags sit in the accessible mid-market of curing and storage solutions.
-
vs. Mason jars: Jars work fine but need regular burping, take up space, break if you drop them, and tie you to humidity packs. Grove Bags do all the work passively.
-
vs. Generic mylar bags: Cheaper alternatives exist, but they don't have TerpLoc's multi-layer oxygen and humidity management — you're comparing a budget ziplock to proper engineered film.
-
vs. C-Vault containers: Similar principle, higher cost, bulkier to store. Growers who've used both usually prefer Grove for sheer convenience.
-
vs. Automated systems (Cannatrol): Those cost thousands. Grove Bags give you 80% of the benefit at a fraction of the price, just with zero automation.
In plain terms: you're paying for clever film technology and the privilege of not having to think about it.
Usage guidance
Grove Bags are designed for one core job: curing and long-term storage of dried plant material.
Preparation before sealing
Dry your material to 55–60% relative humidity before placing it in the bag. This is crucial — too wet and mould risk creeps up; too dry and you've missed the point.
Filling and sealing
Fill the bag to roughly 75% capacity, leaving 25% headspace for air circulation. Don't squeeze out all the air; let the TerpLoc technology do its job. For best results, heat seal the bag after use. The zipper alone loses about 1–2% of the bag's protective properties, so a heat sealer is worthwhile if you're doing this regularly.
Storage location
Store in a cool, dark place. Room temperature is fine. The bag handles humidity passively — no burping, no monitoring, no weekly checks.
Curing duration
Depending on your material and conditions, curing takes 4–10 weeks. After that, the bag becomes a long-term storage solution. Properly sealed and stored material stays fresh for 90 days to over a year, with humidity levels remaining stable around 60% RH.
No maintenance required
This is the real selling point. Unlike jars, you don't open the bag to check humidity, reseal it, and hope you got the balance right. TerpLoc manages it all.

Who this is for
- Growers tired of burping jars multiple times a week
- Anyone running multiple containers where humidity packs cost adds up quickly
- Commercial or semi-commercial operations needing scalable, passive storage
- Growers who want long-term storage without investing in automated curing systems
- Anyone prioritising convenience and odour control alongside preservation
- People who've tried mason jars and found the maintenance annoying
Particularly suited to setups where passive operation and reliability matter more than tradition.
Our take
Grove Bags represent a proper shift from the jar-and-humidity-pack game. The technology is real, the performance is consistent, and you genuinely don't need to think about them once they're sealed. Heat seal them, stick them in a cupboard, and they'll handle the rest.
Are they necessary? No. Are they better than jars? For most growers, yes. Is the convenience worth the cost? If you've got more than a handful of containers, almost certainly.
Good time to buy while stock lasts. One less thing to worry about during the growing cycle.
