DMS Jars Now Being Tested
Why Vacuum Pressure Testing Matters
The DMS™ vacuum jar system is engineered to slow oxidation, preserve terpene structure, and maintain internal moisture balance far beyond what standard storage bags can achieve. By monitoring pressure behavior, color stability, and terpene volatility, these tests demonstrate how cannabis degrades—or resists degradation—during real-time storage.
This page documents ongoing DMS™ oxidation and pressure tests showing measurable differences in aroma retention, color shift, and moisture migration compared to common commercial storage options.
Independent testers are currently evaluating DMS Jars in real curing conditions. Results will be published soon. Each verified report will be linked here for transparency and performance validation.
Early testers are already impressed by the design before even putting it to use — that says everything about its appeal. As feedback rolls in, this limited batch will move quickly. Once the imprinted production run begins, prices will increase due to tariffs, so this is your chance to secure one at the current rate while stock lasts.
Oxidation + Moisture Tests: What the Results Show
Early-stage testing reveals that DMS™ jars maintain terpene integrity and humidity stability for significantly longer intervals. Competing storage methods showed visible oxidation, terpene flattening, and moisture escape within the first 48–72 hours. The DMS™ system maintained pressure retention and minimized aroma loss, confirming slower internal degradation.
These findings support what experienced users report:
DMS™ jars preserve taste, potency, and freshness far more effectively than standard bags or jars.
And now the validation is starting to roll in…
MNGrowin’ reports that after 10 days in the DMS jar, the flower still looks and smells exactly the same as when it was sealed. The results are holding steady — and that’s just the start.
Meanwhile, Catherine Goldberg — with an audience of over 46K subscribers — has confirmed strong interest after covering Pop Back jars for commercial display. Once her readers see a resealable, reusable home version like the DMS™ jar, demand will surge.

Dynamic-Seal Technology™ — the DMS™ system naturally equalizes internal pressure to maintain stable humidity and terpene integrity. Unlike rigid vacuum jars that trap stale air, the DMS design adapts to environmental changes to protect freshness and aroma over time.
After one more week, RH settled perfectly from 63% down to 61% — right in the target zone for long-term terpene
How the DMS™ System Slows Oxidation
The DMS™ process uses controlled vacuum pressure to reduce oxygen exposure inside the jar. Lower oxygen levels mean slower terpene breakdown, slower chlorophyll oxidation, and reduced moisture migration. This creates a more stable environment that protects delicate compounds responsible for flavor, aroma, and smoothness.
When pressure rises during storage, it signals internal changes—moisture movement or terpene activity—allowing real-time observation of the flower’s behavior. DMS™ testing captures these shifts and demonstrates how the system preserves quality over time.
After heat-shrink adhesion, RH stabilized from 63% to 61%. This slow drift shows the jar reaching full internal equilibrium. The wrap plays a passive but critical role—shielding from light and moderating surface temperature fluctuations that can nudge internal RH. Together, they create a controlled terpene and cannabinoid environment that preserves terpene integrity—fresh, volatile, and stable day after day. It’s not just for growers; it’s for medical patients and recreational users who want every purchase to stay as fresh as the day it was sealed.
The last update was just a hint of what was shown — now I have 30 day sample of DMS to a mason jar that's been inside a tote, AND a Zip Zag bag sample. If this doesn't prove the difference, I don't know what else can
Its time to wake up, the tightening is actually bad, and the mason jar 🫙 proves why it is permeable to o2...
Next we have Zip Zag, and while its holding, there is already tell tale signs of the tightening, which means and this extremely important to understand "the tote" is also permeable to o2, but...but humidity is ambient inside a tote— its a smokescreen for complacency, its still slower to oxidize without negative pressure sealing out o2. Most are unaware the new genetics have brought a shorter shelf life as a drawback. DMS extends by 50-75%longer than standard but the sad truth is no harvest goes beyond 18 months regardless of storage to fully degrade into myrcrene hay schwagg. Shake is flat now, it honestly can't be used like the past. So I URGE you to save $$$ to protect and extend the stash/suppply from OXIDATION.
It's important to note testing will continue to 60-90-120 day markers and possibly beyond this, so check back for latest real time updates.
The latest update:
Our first external humidity-stress test is now underway. Conditions have been extremely wet the last few days, yet the jar is holding steady at 61% RH, showing no drift and no internal moisture exchange.
This tester will continue posting readings, and I’ll update the thread as new data comes in.
For clarity: DMS refers to the vacuum jars (Dankmaster Standard), not seeds. These jars are engineered for stability under fluctuating environmental conditions, and this is the first round of real-world verification outside my own controlled tests.
More screenshots and data points will be added as they report in.
We have the latest update, and it is becoming definitive visual evidence of what is actually holding up. You be the judge if DMS™ is worth having after seeing the comparison at 49 days.
I said from the beginning that Zip Zag bags would begin collapsing between Days 45–60, and here we are — right on schedule.
DMS Jar:
Still smells like the day it went in. Terp profile fully intact, structure preserved.
Glass Jar:
Almost no smell unless your nose is directly on top of the bud. Major terpene loss.
Zip Zag Bag:
Nose is still there, but the bud is compressed from oxygen exchange, pressure shifts, and 12+ bags stored together. This is the start of the collapse window I predicted. By Day 60, breakdown accelerates.
This is the moment where long-term storage methods separate themselves — and the DMS™ vacuum jar is proving exactly what we engineered it to do.
What These Tests Prove
The DMS™ vacuum jar does not just store cannabis—it stabilizes it. Pressure readings, color preservation, and terpene retention all indicate significantly slower oxidation rates compared to popular commercial bags. This means better flavor, smoother smoke, longer-lasting quality, and reduced loss of volatile compounds.
As more tests complete, this page will continue to show real, verifiable evidence of how the DMS™ system outperforms standard storage methods.
