Heavy-Duty Reinforced Construction

The Gorilla FlexPro Water Tank is manufactured with a reinforced, heavy-duty structure designed to provide dependable water storage for demanding horticultural environments.

Its flexible body offers an effective alternative to traditional rigid reservoirs while maintaining the strength needed for everyday use.

Whether installed in a grow room, greenhouse or sheltered outdoor growing area, the Gorilla FlexPro is designed to provide convenient access to stored water.

Collapsible Design for Easy Storage

Unlike rigid plastic water butts, the Gorilla FlexPro can be dismantled and folded away when empty.

This makes it particularly useful for growers who need to transport water storage equipment through narrow doorways, change their growing layout or store reservoirs between growing cycles.

The flexible construction also helps reduce the storage space required when the tank is not in use.

Quick Tool-Free Assembly

Gorilla FlexPro Water Tanks are designed for straightforward assembly without specialist tools.

Once assembled and positioned on a suitable level surface, the tank can be filled with water and connected to compatible irrigation equipment.

This makes the FlexPro particularly practical for temporary setups, seasonal growing environments and installations where transporting a large rigid tank would be difficult.

Pre-Welded 19mm Tank Connector

Each Gorilla FlexPro Water Tank includes a pre-welded 19mm tank connector, providing a convenient connection point for compatible water distribution equipment.

The pre-welded construction helps provide a secure outlet connection without the need to cut an additional opening into the flexible tank body.

This makes it easier to integrate the tank into compatible hydroponic watering and irrigation systems.

Additional 16mm Fitting Included

The Gorilla FlexPro also includes an additional 16mm fitting, providing greater flexibility when connecting the tank to compatible irrigation components.

This is particularly useful for hydroponic systems that use 16mm irrigation pipework or associated fittings.

Important: Check the exact connection requirements of your irrigation equipment before installation. Additional adapters, tubing or connectors may be required.

Convenient Outlet Tap

The integrated outlet tap allows stored water to be dispensed without lifting or tipping the reservoir.

It is particularly useful for:

Filling watering cans and smaller containers
Dispensing prepared hydroponic nutrient solutions
Connecting compatible irrigation pipework
Managing water flow during reservoir maintenance
Accessing stored water for greenhouse watering

Ideal for Hydroponic Nutrient Reservoirs

The Gorilla FlexPro is suitable for storing water and compatible hydroponic nutrient solutions.

It can be used as a central reservoir for a variety of growing systems, including compatible automatic watering, drip irrigation and recirculating hydroponic installations.

Its range of capacities makes it suitable for both smaller home growing setups and larger horticultural systems.

Compatible with Automated Irrigation Systems

The Gorilla FlexPro can be incorporated into compatible automated watering systems using suitable pumps, tubing, fittings and irrigation controls.

Its 19mm tank connector and additional 16mm fitting provide useful connection options for a range of irrigation installations.

Depending on your system, the reservoir can be used to supply water or prepared nutrient solutions to multiple growing containers.

Please Note: Pumps, timers, irrigation controllers and additional pipework are not confirmed as included with the tank and should be selected separately as required.

Suitable for Indoor & Outdoor Growing

Gorilla FlexPro Water Tanks are designed for both indoor and outdoor horticultural environments.

They can be used in grow rooms, greenhouses, gardens and other suitable locations where convenient water storage is required.

For best results, position the tank on a stable, level surface and protect it from sharp objects, accidental impact and extreme environmental conditions.

Automatic watering systems
Drip irrigation systems
Greenhouse watering
Grow room water storage

How to Choose the Right Gorilla FlexPro Water Tank

When selecting a tank, consider the following:

Water Capacity: Choose a reservoir that can store sufficient water for your irrigation schedule.
Number of Plants: Larger growing systems generally require greater water storage capacity.
Watering Frequency: Frequent irrigation cycles may require a larger reservoir.
Available Floor Space: Check the assembled dimensions of your selected tank.
Outlet Compatibility: Ensure the supplied 19mm and 16mm fittings suit your irrigation equipment.
Maintenance Access: Allow enough room for filling, cleaning and checking the reservoir.

Installation & Maintenance Tips

Choose a flat, stable surface capable of supporting the weight of the filled tank.
Assemble the tank according to the supplied instructions.
Check that the tank body and supporting structure are correctly positioned.
Ensure the outlet tap and fittings are securely installed.
Partially fill the tank and inspect for leaks before filling completely.
Connect compatible irrigation equipment where required.
Check all connections and test the watering system before leaving it unattended.
Clean the tank periodically to prevent nutrient residue and sediment accumulating.
Empty, rinse and dry the tank before collapsing it for storage.

Important: Never attempt to move a flexible tank while full. A 750L tank contains approximately 750kg of water, excluding the weight of the tank and any connected equipment. Always ensure the floor can safely support the filled reservoir.
