Integra Boost 420g 72% Humidity Packs Are the Dry-Climate Option
A six-pound bin in a dry room is where the small packs stop making sense. You would need six or seven 67 g packets spread through it, and half of them would be nowhere near the material that needs them. One 420 g pack covers the same load in a single 8.5in x 5in packet, Integra's largest. It holds 72% RH, the dry-climate setting rather than a wetter one. Dry air pulls moisture through a seal faster than damp air does. Every pack is individually overwrapped with an indicator card, shipping as eight displays of five. The fill is the same salt-free plant-based blend used across the line, just a lot more of it.
420g Packs for Humidors and Dry Rooms, From First Use to Swap
A 420 g pack outlasts the small sizes. That changes how it gets managed. Sealed in its overwrap it stays inert on a shelf and spends nothing. Opened into a bin it starts trading moisture immediately and keeps going for months rather than weeks, simply because there is more of it. The card in the wrapper is what closes that loop, since nobody wants to guess at this size. When the dot turns, the packet comes out and a fresh one goes in; the bin itself never changes. Integra also lists 72% for humidor seasoning and for stepping humidity down during a cure, both of which are short jobs rather than storage settings. Cured flower belongs at 55% or 62%, so this tier should follow the room and the goods rather than the size of the container. The trade-off is commitment, because 40 packs of the largest size is a lot of capacity to hold in stock.
Key Features
- 420 g, the Largest Integra Pack: One pack covers what would otherwise take six 67 g packs spread through a bin.
- Rated Up To 6 lb of Contents: A pound more headroom than the 320 g in the same display format.
- 72% RH, the Dry-Climate Tier: Integra separates 69% and 72% by ambient climate rather than by product.
- Eight Displays, 40 Packs Per Case: A retail-ready configuration rather than a carton of loose stock.
- Individually Overwrapped: Each pack stays inert on the display until a customer opens it.
- Replacement Indicator Card Included: The dot signals when the pack is finished, so the end user is not guessing.
- Also Used for Seasoning: Integra lists 72% for humidor seasoning and for stepping RH down during a cure.
- 100% Salt-Free Formula: Plant-based glycerin and water, so no salt crystals settle onto the contents.
- Spill-Proof and Tear-Resistant: A pack this size gets handled a lot and stays pliable rather than splitting.
- Four RH Levels at This Size: 420 g comes at 55%, 62%, 69% and 72% RH, so the tier can be matched to the goods.

What Is the Difference Between 69% and 72%?
Ambient conditions. A dry room loses moisture through a seal faster, so Integra sets 72% for those and 69% for damper ones.
How Much Does a 420g Pack Hold?
Up to 6 lb of contents. That is a large tote, a five-gallon pail or a full cabinet humidor rather than a jar.
What Exactly Ships in the Master Case?
Eight retail displays of five packs each, 40 packs in total. The case is sold whole and the displays are not broken out.
Is 72% Right for Storing Flower?
No. Integra directs cured flower to 55% or 62% RH. 72% runs well above that window and suits smokeable goods and seasoning work.
