SuperTank Flexible Tank – Collapsible Water Reservoir

A Light-Blocking Reservoir That Folds Flat When You Don't Need It

A rigid 1000L tank is a genuine headache to get into most grow spaces - it won't fit through a standard doorway, it's awkward to manoeuvre once full-sized, and it takes up permanent floor space whether you're using it or not. The SuperTank Flexible Tank solves both problems: it's built from a heavy-duty, light-blocking fabric that packs flat for transport and storage, then assembles on site using a set of support poles and feet that hold it rigid once filled, giving you full 1000-litre capacity from a tank that can travel through gaps a solid reservoir never could.

Because the tank material blocks light penetration, algae growth in the stored water or nutrient solution is significantly reduced compared with a translucent rigid tank left standing for days at a time - a genuinely practical benefit for anyone running a static reservoir feeding a flood-and-drain or dripper system. An overflow connection is built in to catch accidental overfilling before it becomes a flood, and the tank is designed to connect straight into most existing watering systems rather than requiring bespoke fittings.

It's available with a fitted front tap using a push/snap-fit connector for instant hookup to snap-fit hosing, or without a front tap for growers running their own pump-through or bulkhead fitting into an external system. At full capacity the assembled tank stands roughly 120cm across and 100cm tall, so plan floor space accordingly before you commit to the 1000L size.

For smaller setups the same tank comes in 100 litre and 225 litre sizes, each with or without the front tap. Both stand about 80cm tall when full: the 100L is roughly 40cm across and the 225L roughly 60cm across, so either fits in the corner of a grow tent or under a bench as a nutrient reservoir or water store.

• 100, 225 or 1000-litre capacity, fold-flat storage - full-size reservoir that transports and stores like a rolled-up tent
• Light-blocking fabric - meaningfully cuts algae growth versus a translucent rigid tank
• Snap-fit tap connection (With Front Tap option) - instant hookup to snap-fit hose pipe, no tools required
• Built-in overflow connection - catches accidental overfilling before it becomes a spill
• Fits through standard doorways - where an equivalent rigid 1000L tank simply won't go
• Freestanding once assembled - support poles and feet included, no external frame needed
