Stash & storage

We'll only email you about this product — no marketing.
The RAW Weed Curing Jar is a glass Mason jar designed specifically for curing and storing cannabis buds. Available in three sizes — 177ml, 295ml, and 473ml — these airtight containers lock in terpenes, prevent mould, and keep your flowers at the right moisture level for months. RAW's signature branding gives them a clean, modern look that works on a shelf or tucked away in a cupboard.
| Variant | Capacity | SKU | Best for |
|---|---|---|---|
| Small | 177ml | HS1722 | A few grams — personal stash, single strain samples, or travel-sized storage |
| Medium | 295ml | HS1723 | Around 7-14g — the sweet spot for most home growers curing a single strain |
| Large | 473ml | HS1724 | 14-28g — bulk curing after harvest or long-term storage of your main supply |
If you're curing a fresh harvest, go bigger than you think — buds need headroom for air exchange during the first few weeks. If it's purely for day-to-day storage of already-cured weed, the Small or Medium will do the job.

Complete your setup: pair these curing jars with a RAW rolling tray and RAW rolling papers for a fully branded station. If you're growing your own, a digital hygrometer small enough to drop inside the jar makes curing much easier — you can monitor humidity without opening the lid every few hours.
We get it — you've just harvested, dried, and trimmed your buds. The temptation is to stuff them into whatever container is lying around: a sandwich bag, a plastic tub, that old coffee tin from the kitchen. And honestly, for a day or two, that might not ruin anything. But curing is where good weed becomes great weed, and the container you use makes a real difference.
Here's the problem with plastic bags and non-airtight containers: they let moisture escape too quickly, which dries out your buds and destroys the terpenes that give each strain its flavour and aroma. On the flip side, containers that trap too much moisture without a proper seal can create pockets of humidity where mould thrives. We've seen people lose entire harvests to a dodgy Tupperware lid that didn't quite click shut. Glass is the answer because it's non-porous — it doesn't absorb smells, doesn't leach chemicals, and doesn't let air creep in or out when the lid is sealed.
The RAW Weed Curing Jar is a Mason-style glass jar with an airtight lid, which is exactly what you want for the 2-4 week curing window. You open the jar once or twice a day for a few minutes (called "burping"), let the excess moisture escape, then seal it back up. The glass walls keep the internal environment stable between burps. After curing, the same jar becomes your long-term storage solution — buds can stay fresh for 6 months or more when kept in a cool, dark spot inside an airtight glass container.
After 25+ years behind the counter, we can tell you the single most common storage mistake: people use containers that are too big for the amount of weed they're storing. A half-empty 473ml jar means a lot of air sitting on top of your buds, which speeds up oxidation and dries things out. Match your jar size to your stash size. If you've got 5 grams, the Small (177ml) is better than the Large, even if the Large looks more impressive on your shelf.
One honest limitation of any glass jar, including this one: glass is transparent. Light degrades THC into CBN over time, which makes your weed less potent and more sleep-inducing. RAW's jars look great on display, but if you're storing long-term (2+ months), keep them in a dark cupboard rather than on a sunny windowsill. That's not a flaw in the product — it's just how glass works. If you want something opaque, you'd need a UV-blocking container, but those tend to be less attractive and more expensive.
Compared to generic Mason jars from a kitchen shop, the RAW Weed Curing Jar is essentially the same concept — glass body, airtight lid — but with RAW's branding and a slightly more contemporary design. The seal quality is solid. We'd pick these over a random jar from a supermarket because the lid actually fits properly every time, and they're sized specifically for cannabis quantities rather than jam-making quantities. The 177ml Small is genuinely small enough for a personal stash, which is surprisingly hard to find in regular kitchenware.
Yes. The airtight glass design works for both the active curing phase (first 2-4 weeks with daily burping) and long-term storage afterwards. Just keep the jar in a cool, dark place once curing is complete.
Roughly: the Small (177ml) holds 3-7g, the Medium (295ml) holds 7-14g, and the Large (473ml) holds 14-28g. Actual capacity depends on bud density and how tightly you pack — but don't pack tightly during curing. Leave 25% headroom.
During active curing, no — burping handles moisture regulation. For long-term storage after curing, a 62% Boveda or Integra Boost pack inside the jar helps maintain stable humidity and keeps buds fresh for months without any effort on your part.
Glass is non-porous, so it doesn't absorb or release odours and won't leach chemicals into your buds. Plastic containers can build static that pulls trichomes off your flowers and may impart a faint plastic taste over time. Glass is the better choice for anything beyond a day or two.
When the lid is sealed, the airtight closure keeps aromas locked inside. You won't smell anything unless you open the jar. During the burping phase of curing, you'll obviously release some scent each time you pop the lid — that's unavoidable and part of the process.
Wash with warm water and a drop of unscented washing-up liquid, then rinse thoroughly and let it air dry completely before adding new buds. Any residual moisture inside the jar can cause mould on your next batch, so make sure it's bone dry.
The glass body is dishwasher-safe, but we'd hand-wash the lid to preserve the airtight seal over time. High heat and harsh detergents can degrade rubber gaskets faster than gentle hand washing.
