AutoPot FlexiTank - Collapsible Reservoir for AutoPot and Hydroponic Systems
Best for: growers who need a large-capacity reservoir for an AutoPot or other gravity-fed system, but don't want a rigid tank taking up permanent floor space.
Our thoughts
This is AutoPot's own take on the collapsible tank idea - pole-and-liner construction that folds flat when empty and stands up as a full-size reservoir once assembled. Straight out of the box in a few minutes, and available in a wide enough size range to suit anything from a single small tent to a serious multi-room setup.
The AutoPot FlexiTank range is a collapsible reservoir built to feed AutoPot systems (or any gravity-fed hydroponic setup) without the storage headache of a permanent rigid tank. Each FlexiTank uses a flexible liner supported by internal poles, so it packs down flat for storage or transport and only takes a few minutes to assemble - fit the poles into the sleeves, add the tap, and it's ready to fill. Once up, it holds a genuinely large volume in a comparatively small footprint.
The range spans several sizes to suit different setups, from a compact 100L tank (roughly 43cm diameter x 75cm tall) suited to a single tent or closed space, up to a 750L tank (around 90cm diameter x 120cm tall) for larger or commercial-scale grows, with a 400L option (around 68cm diameter x 111cm tall) in between.
How it compares
The FlexiTank sits in the same collapsible-reservoir category as Aqualine's Flex Tanks, which use the same pole-and-liner principle.
- Same core mechanism as Aqualine Flex Tanks - a flexible liner supported by internal poles, packing flat when empty.
- Far less storage space required than a rigid water butt or IBC tank of equivalent capacity.
- Purpose-designed to pair with AutoPot's own AQUAvalve systems and modules, though it works with any gravity-fed or pumped setup.
If you're already running non-AutoPot equipment and just need extra water storage, Aqualine's Flex Tanks do a similar job - but if you're on an AutoPot system, the FlexiTank is the natural fit and sized to match AutoPot's own module ranges.
Usage guidance
Setup takes minutes and doesn't need any tools.
Assembly
Unfold the liner, slot the support poles into the sewn sleeves, fit the tap, and fill with water once it's positioned where you want it.
Sizing to your system
Match tank capacity to the number of pots and watering frequency in your AutoPot layout - the 100L suits a single small tent, while 400L-750L suits larger or multi-tent setups.
Positioning
Set it up on a flat, stable surface before filling, since a full tank is heavy and difficult to move.
Storage between grows
Empty, clean and fully dry the liner before folding it flat for storage.

Who this is for
- AutoPot growers who need a reservoir sized to their existing module layout.
- Growers with limited permanent floor space who need a large tank that can be stored away between grows.
- Multi-tent or multi-room setups needing several tanks that can be moved or reconfigured easily.
Best suited to AutoPot systems, though equally useful for any gravity-fed hydroponic setup needing extra reservoir capacity.
Our take
It's a well-proven design - the same collapsible principle used across the category - built specifically to match AutoPot's own module sizes, which makes it the obvious pairing if you're already running AutoPot kit. The size range means you're not stuck buying more capacity than your setup actually needs.
If you're running or building out an AutoPot layout, this is the natural reservoir choice. One we sell a lot of for new growers setting up their first AutoPot system.
