Flexi Tank Pro — Reflective Collapsible Reservoir Tank

Flexi Tank Pro — Premium Reflective Collapsible Reservoir Tank

An evolved version of the original FlexiTank — fully collapsible reservoir that reduces to a fraction of its assembled size for storage. The Pro variant adds a reflective white exterior skin (prevents sunlight absorption, helps maintain solution temperature) plus a 100% waterproof, specially-sealed exterior for maximum durability. The right reservoir for growers tight on storage space between grows.

Why growers choose the Flexi Tank Pro:

• Fully collapsible design — reduces dramatically for storage between grows
• Reflective white exterior skin — prevents sunlight absorption, maintains solution temperature
• 100% waterproof construction — proper sealed exterior, no leak risk
• More durable than original FlexiTank — pro-grade enhancement on a proven design
• User-friendly fill/drain — designed enhancements simplify tank management
• Stable in temperature swings — exterior skin reduces solution heating
• Suitable for hydroponic reservoir use — proper grow-room reservoir, not a generic tub

Who it's not for:

For permanent installations, rigid plastic tanks (75L Bag Tank, 110L Round Tank) are cheaper and more durable long-term. For very small setups, a 25L bucket is adequate and simpler. Flexible tanks need a flat stable base — uneven floors can stress the seams. For automated topping-up, a float-valve system pairs cleanly with the Pro for hands-off reservoir management.
