TightVac 2.35l – Large-Format Vacuum Storage for Seasonal Harvest Archiving
When production volumes outgrow standard containers, the TightVac 2.35l delivers the capacity to match. Holding 145–150 grams of dry herbs in a stable 26 x 12.5 cm footprint, this is one of the largest containers in the TightVac system – built for home use but robust enough for intensive grow room environments. Explore the complete TightVac collection to build a tiered storage system scaled to every stage of your grow cycle.
How to Use the TightVac 2.35l
Fill the container to your desired level – up to approximately 150 grams depending on density and bud structure. Seat the lid firmly and press the vacuum button once: the patented one-way valve expels residual air and the hermetic seal engages immediately. The valve also allows naturally accumulated CO₂ to vent gradually without admitting oxygen – particularly valuable for freshly roasted coffee and herbs undergoing an active cure cycle. For freezer storage, always allow the sealed container to return fully to room temperature before opening to prevent condensation on the contents. Clean periodically with isopropyl alcohol or soapy water; dry the valve completely before resealing. With correct maintenance, the TightVac 2.35l is rated for a service life of up to 10 years.
Use Cases & Applications
- Multi-genetics archiving: store multiple strains in dedicated containers or archive a full season's harvest in a single organised, labelled, airtight unit.
- Full seasonal harvest storage: the large capacity handles an entire grow cycle in one hermetic unit, equally effective at room temperature and in the freezer.
- Long-term freezer preservation: NSF-certified materials are fully rated for sub-zero temperatures, enabling multi-month preservation of large harvest volumes without freeze-drying or seal failure.
- Bulk coffee beans & grounds: the 2.35l holds up to 680g of coffee; the one-way valve manages CO₂ degassing without oxygen ingress – optimal storage for specialty coffee.
- Pantry organisation at scale: rice, flour, sugar, pasta, protein powder – hygienic bulk food storage that prevents weevil infestation and maintains quality longer than standard packaging.
- Long-term seed & pollen library: the dry, low-oxygen environment preserves germination viability and pollen activity across multiple grow seasons.
Material Certifications & 10-Year Durability
The TightVac 2.35l is manufactured from NSF International and FDA-approved food-grade plastic, BPA-free – the highest food safety certifications available for storage containers. These certifications confirm the material is safe for all consumable contact, including dried herbs, foods and supplements. The 12.5 cm diameter provides stability on any surface and makes large-batch filling and dosing straightforward. The robust construction resists insect infestation: the hermetic seal prevents larvae and weevils from accessing the contents. Designed and rated for up to 10 years of active use, the 2.35l represents the most durable investment in the TightVac range.

How long does the TightVac 2.35l last and can it store multiple herb strains simultaneously?
With correct use and maintenance, the TightVac 2.35l is rated for up to 10 years of service – significantly longer than most competing containers. Its 145–150 gram capacity easily accommodates multiple strains stored together, or you can dedicate individual 2.35l containers to separate genetics for fully organised archiving. NSF and FDA-certified materials ensure food safety across the entire service life, including freezer storage. Clean the valve with isopropyl alcohol periodically and dry it completely before resealing to maintain optimal vacuum performance throughout the container's lifespan.
