SmartGro Flexible Water Tanks

The SmartGro Flexible Water Tanks provide a practical, space-saving solution for storing water and prepared nutrient solutions in hydroponic grow rooms, greenhouses and indoor growing environments. Also known as the SmartGro Water Butt, this flexible water storage system offers a convenient alternative to bulky rigid reservoirs, making it particularly useful for growers who need dependable storage without permanently sacrificing valuable floor space.

Manufactured from durable, leak-resistant material, these collapsible water tanks are designed for everyday use in growing environments. Their flexible construction makes them easier to transport and store when not required, while tool-free assembly allows growers to set up their water storage quickly and conveniently.

Available in five capacities ranging from 100L to 1,000L, SmartGro Flexible Water Tanks can accommodate different cultivation requirements, from smaller indoor growing setups to larger irrigation and nutrient storage applications. Built-in internal measurement markings also make it easier to monitor water levels and manage the volume of nutrient solution held in the reservoir.

Who It’s For

SmartGro Flexible Water Tanks are ideal for growers who need reliable water storage while making efficient use of their available growing space. They are particularly suitable for hydroponic growers, indoor gardeners, greenhouse cultivators and anyone preparing nutrient solutions for regular plant feeding.

Smaller growing operations can benefit from the compact, flexible design, while larger setups can take advantage of the higher-capacity options for storing greater volumes of water or nutrient solution. The tanks are also useful for growers who frequently rearrange their equipment, operate temporary cultivation spaces or want a collapsible hydroponic reservoir that can be stored more conveniently than a rigid plastic tank when not in use.

How To Use

Choose the Appropriate Capacity: Select a SmartGro Flexible Water Tank that provides enough water storage for your plants, irrigation system and intended feeding schedule. Allow sufficient space around the reservoir for filling, inspection and routine maintenance.

Assembly: Position the tank on a firm, level surface capable of supporting its weight when full. Assemble the flexible reservoir using its supplied components according to the manufacturer's instructions. The tank is designed for tool-free assembly, so specialist installation equipment is not required.

Filling: Check that the reservoir is correctly assembled and stable before adding water. Fill gradually and inspect the tank for any signs of leakage. Use the internal measurement markings to monitor the volume of water being added and avoid overfilling.

Preparing Nutrient Solutions: When using the tank for hydroponic nutrient storage, add the required nutrients to the water according to the nutrient manufacturer's instructions. Mix thoroughly and check the final pH and EC where appropriate for your growing method. Use the prepared solution for manual watering or with a compatible irrigation system.

Routine Maintenance: Check water levels regularly and replenish the reservoir as required. Inspect the tank for wear or leaks, and clean it periodically to minimise sediment, nutrient residue and contamination. Keep the reservoir in a suitable location away from sharp objects or surfaces that could damage the flexible material.

Storage: When the tank is no longer required, empty it completely, clean it and allow it to dry. Disassemble it according to the manufacturer's instructions and store the flexible components in a clean, dry location until the next use.
