Description
Extra reservoir capacity that folds flat when you're done
FlexiTank Collapsible Water Butts give you additional reservoir or nutrient-tank capacity without the permanent footprint of a rigid tank. They arrive flat-packed in a discreet box, assemble in a few minutes, and fold back down for storage or transport once empty - handy both as a main gravity-fed reservoir for Autopot systems and as spare mixing capacity you can tuck away between grows. A strong rubber gasket around the lower exit outlet keeps the connection watertight once built, so there is no leak risk at the drain point.
Key Benefits
- Folds flat for easy storage and transport between uses.
- Sealed rubber gasket outlet stops leaks at the lower exit point.
- Works with Autopot and other gravity-fed irrigation setups.
- Multiple size options to suit anything from a single tent to a larger grow area.
- Quick to assemble and dismantle with no permanent fittings required.
How to Use
- Build: unfold the tank and assemble the frame per the included instructions.
- Check the seal: fit the liner and confirm the outlet gasket is seated correctly before filling.
- Position: place it level and stable, then fill with water or nutrient solution.
- Connect: link the lower outlet to your Autopot system or irrigation line.
- Store: once empty and fully dry, fold flat for storage until next use.

Yes. Connect the lower outlet to your AutoPot or other gravity-fed irrigation line. AutoPot recommend a filter on 16mm pipe systems to keep sediment out of the pipework.

No. It arrives flat-packed, assembles in a few minutes, and folds back down for storage once it's empty and fully dry.
Will the outlet leak?
A rubber gasket seals the lower outlet. Check the gasket is seated before filling, and stand the tank level and stable.
