FLEXITANK (WITH TAP) COLLAPSIBLE RESERVOIR

Description

Flexitank (With Tap) Collapsible Reservoir is a flexible, foldable nutrient reservoir designed to hold mixed nutrient solution for gravity-fed growing systems, manual watering, and any application where a rigid tank would be impractical or take up unnecessary permanent space. We have been recommending Flexitank reservoirs to UK growers since 2017 as one of the most convenient and space-efficient solutions for nutrient storage in the grow room.

Practical Gravity-Fed Nutrient Storage

The Flexitank’s collapsible construction means it stores flat when not in use — a significant advantage over rigid plastic tanks in grow rooms where space is managed carefully. When filled, it holds its shape through the internal structure of the flexible material and the weight of the nutrient solution, requiring no rigid frame or housing. The integrated tap at the base allows you to connect gravity-fed growing systems — including AutoPot systems — directly without the need for additional pump fittings or adapters.

The Flexitank is manufactured from food-grade, UV-stabilised material that is safe for use with hydroponic nutrients and does not leach plasticisers or contaminants into your nutrient solution. The dark-coloured material prevents light penetration that would otherwise promote algae growth inside the reservoir — a common and frustrating problem with clear or light-coloured storage containers.

Sizes, Setup and Maintenance

Available in multiple litre capacities to suit different growing system sizes. Fill with pre-mixed, pH-adjusted nutrient solution and position at the appropriate height for your gravity-fed system — AutoPot systems require the Flexitank base to be at or above the height of the AQUAvalve trays for reliable flow. Clean between growing cycles with a sterilising agent and allow to dry fully before storage.

Compatible with AutoPot systems, dripper systems, and any other gravity-fed application. The integrated tap provides a controlled flow connection point for 13mm irrigation hose. A practical, affordable and space-efficient reservoir solution for the modern UK grow room.
