Stash & storage
by Integra Boost
Integra Boost 55 is a two-way humidity control pack that maintains a consistent 55% relative humidity inside your storage jar, keeping cured flowers fresh, flavourful, and free from mould. It works both ways — releasing moisture when the air inside your jar gets too dry and absorbing it when things get too damp. Drop one in, close the lid, and stop worrying about your stash drying out or going off.
We've stocked these behind the counter for years, and they're one of those small purchases that genuinely saves product. A single crispy, over-dried batch teaches you the lesson fast — proper humidity control isn't optional if you want your flowers to smoke smooth and taste the way they should.
Integra Boost 55 comes in two sizes. The choice is straightforward — it depends on how much you're storing:
| Variant | Weight | Best For |
|---|---|---|
| 8g pack | 8 grams | Small jars up to roughly 12 grams of flower. Toss one into a standard mason jar or stash container. |
| 67g pack | 67 grams | Larger containers, turkey bags, or curing buckets holding 450g (1 lb) or more. One pack covers the full volume. |
If you're unsure, go bigger. An oversized pack won't push humidity above 55% — the two-way technology caps it there. An undersized pack just runs out faster.
The 55% mark is the sweet spot for long-term flower storage. Below 50%, trichomes become brittle, terpenes evaporate faster, and your material smokes harsh and hot. Above 65%, you're inviting mould — and once mould takes hold, the entire jar is finished. At 55% RH, the cell structure stays intact, terpene profiles hold, and there's not enough moisture for mould spores to colonise.
We get asked about this constantly in the shop: "Why does my stuff taste different after a few weeks in a jar?" Nine times out of ten, it's humidity. An unsealed jar in a Dutch winter can swing from 40% to 70% RH in a single day. That kind of fluctuation degrades quality faster than you'd expect. The Integra Boost 55 acts as a buffer, absorbing those swings and keeping conditions stable inside the jar regardless of what the weather's doing outside.
The difference is noticeable. Material stored at a stable 55% RH for four weeks smells noticeably richer and smokes noticeably smoother than the same batch left in an unregulated jar. It's one of those things you can't un-learn once you've tried it side by side.

Most humidity packs on the market — Boveda being the obvious comparison — use a saturated salt solution sealed inside a membrane. They work, but they come with trade-offs. Salt-based packs stiffen as they dry out, making them prone to tearing. If a salt pack rips inside your jar, you've got salt granules on your flowers. Not ideal.
Integra Boost uses a salt-free, plant-based formula. The packs stay pliable throughout their lifespan, which means less risk of tears and zero risk of salt contamination. The included indicator card is a genuine advantage too — it's a separate card that changes colour when the pack is spent. With salt-based alternatives, you're squeezing the pack and guessing. With Integra, you glance at the card. Done.
Honest limitation: Integra packs don't last forever. In a well-sealed jar, an 8g pack typically lasts 2–3 months before the indicator tells you it's time to swap. In a container you open frequently, that drops to 4–6 weeks. Budget for replacements if you're storing long-term — they're cheap enough that it's not a problem, but don't expect one pack to last a year.
Complete your storage setup with airtight stash jars — a proper seal makes your Integra Boost pack last significantly longer. We also carry Integra Boost packs at 62% RH if you prefer a slightly higher humidity for shorter curing periods.
We've carried Integra Boost packs since they first hit the European market, and a few things come up repeatedly. First: people underestimate how much difference a sealed container makes. We've had customers come back saying the pack "didn't work" — turns out they were using a tin with a loose-fitting lid. The pack was fighting a losing battle against constant air exchange. Use glass with a rubber-gasket seal and you'll get the full 2–3 months out of an 8g pack.
Second: 55% versus 62% is a real choice, not just a number. If you're storing material that's already well-cured and you want to keep it at that level for weeks or months, 55% is the one. If you're still in the active curing phase and want slightly more moisture to slow things down, 62% gives you that. We'd pick 55% for finished product every time — it's the drier end of the safe range, which means less mould risk and a crisper smoke.
Third: don't reuse spent packs. Once the indicator card tells you it's done, it's done. We've seen people try to "recharge" them by leaving them in a humid bathroom. It doesn't work — the internal chemistry is a one-way process. Fresh packs are cheap. Just swap them out.
In a well-sealed glass jar, an 8g pack lasts roughly 2–3 months. The 67g pack lasts a similar duration in a proportionally larger container. Opening the jar frequently shortens the lifespan to around 4–6 weeks. The included indicator card tells you exactly when it's time to replace.
No. The salt-free formula and food-grade inks are specifically designed to be inert. Unlike some salt-based alternatives that can impart a faint mineral note over long storage, Integra Boost leaves terpene profiles completely untouched.
The number is the target relative humidity. 55% is drier — best for long-term storage of fully cured material. 62% retains more moisture, which suits active curing or material you plan to use within a few weeks. For most people storing finished product, 55% is the safer bet against mould.
Yes. For containers larger than the recommended coverage of a single pack, use multiple packs. Two 8g packs in a medium jar won't push humidity above 55% — the two-way regulation caps it there. You're just extending the effective lifespan.
The indicator card sits inside your jar alongside the humidity pack. It contains a moisture-sensitive dot that changes colour — typically from blue to pink — when the pack can no longer maintain 55% RH. It's hands-free and requires no calibration. Just glance at it when you open the jar.
No. Once the indicator card shows the pack is spent, replace it with a fresh one. The internal chemistry cannot be recharged or reactivated. Attempting to rehydrate a spent pack won't restore its two-way regulation ability.
Integra Boost is salt-free, which means the packs stay flexible and won't deposit salt crystals if they tear. The separate indicator card gives you a clearer read on pack life than squeezing a Boveda and guessing. Both regulate humidity effectively — the practical differences come down to salt-free peace of mind and easier monitoring.
