TightVac KiloVac 3.8l – The Ultimate Bulk Vacuum Container for Serious Growers
At the top of the TightVac range sits the KiloVac 3.8l – a vacuum storage container built for growers who operate at scale. With a capacity of approximately 250 grams of dry herbs, a wide-mouth opening of 18 cm diameter and a total volume of 3.8 litres, the KiloVac is the most versatile container in the lineup – equally at home in a grow room, kitchen or cellar. Browse the complete TightVac collection to find the right size for every use case.
How to Use the TightVac KiloVac 3.8l
The wide-mouth 18 cm opening sets the KiloVac apart from every other model in the range: it accommodates scoops, large spoons and bulk filling in a way that compact formats simply cannot. Fill to your desired level – up to approximately 250 grams of dry herbs or up to 1 kg of dry goods depending on density. Seat the lid firmly and press the vacuum button once: the patented one-way valve expels residual air and the hermetic seal locks in immediately. The valve also manages gradual CO₂ venting from freshly cured herbs or freshly roasted coffee without admitting oxygen. For freezer use, always allow the sealed container to return 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. The EU-certified food-grade polystyrene #6 is rated for both freezer temperatures and intensive daily use.
Use Cases & Applications
- Bulk dry herb storage: archive up to 250 grams in a single hermetically sealed unit – the go-to solution for growers who harvest in large batches.
- Multi-genetics library: the large interior dimensions allow multiple smaller bags or sub-containers to be organised within a single KiloVac unit.
- Kilo-scale coffee storage: the KiloVac is designed for 1 kg of coffee beans or ground coffee; the one-way valve handles CO₂ degassing from freshly roasted beans without oxygen ingress.
- Long-term freezer preservation: EU-certified materials are fully rated for sub-zero temperatures, enabling multi-month preservation of large harvest volumes without freeze-drying or seal failure.
- Insect & pest prevention: the hermetic seal effectively prevents beetles, moths and their larvae from accessing or contaminating the contents.
- Bulk pantry organisation: rice, flour, sugar, pasta, protein powder, pet kibble – hygienic large-scale dry goods storage that keeps contents fresh significantly longer than standard packaging.
Wide-Mouth Ergonomics & Recyclable Design
What fundamentally distinguishes the KiloVac from the rest of the TightVac range is not just capacity but ergonomics at scale. The 18 cm opening allows tools – scoops, large spoons, portion cups – to be used directly inside the container, dramatically reducing waste and mess during high-volume operations. The stable 18 cm base diameter prevents tipping on any work surface. EU-certified food-grade polystyrene #6 is fully recyclable at end of life – a deliberate material choice for growers who prioritise reducing their environmental footprint. The KiloVac is the storage investment that grows with your production, from a single large harvest to a long-term, organised genetic archive.

How much dry herb fits in the TightVac KiloVac 3.8l and what makes it different from smaller TightVac models?
The TightVac KiloVac 3.8l holds approximately 250 grams of dry herbs, or up to 1 kg of denser dry goods such as coffee or grain. What sets it apart from smaller TightVac models is its wide-mouth 18 cm opening, which allows scoops and large tools to be used directly inside – essential for bulk operations. It uses the same patented one-way vacuum seal technology as every other TightVac model, is fully freezer-safe, and is made from recyclable EU-certified food-grade polystyrene #6. It is the only model in the range specifically designed for bulk-scale storage at the kilo level.
