🌱 Plant It Flexible Tanks — Guide & Product Information

💧 Collapsible Water Storage for Hydroponics, Gardens and Irrigation

Plant It Flexible Tanks are practical collapsible water storage tanks designed for growers and gardeners who need reliable reservoir capacity without the bulk of a rigid plastic tank. They are suitable for hydroponic systems, garden water storage, greenhouse watering, grow room reservoirs and rainwater collection.

Because they are flexible and easier to store when not in use, these tanks are ideal for grow rooms with tight access, temporary setups, seasonal use or larger watering systems where a rigid tank may be awkward to move or position.

  • Collapsible water storage tank design
  • Suitable for water and nutrient solution storage
  • Easier to store away than rigid tanks

📦 Size Variations

Plant It Flexible Tanks are available in five useful capacity options, making it easier to match your reservoir size to your grow system, plant count, watering routine and available space.

  • 100L — ideal for compact grow rooms, small gardens and lighter water storage needs
  • 250L — suitable for medium systems and regular reservoir use
  • 500L — useful for larger grow rooms, greenhouses and irrigation setups
  • 750L — ideal for high-capacity watering and larger reservoir-based systems
  • 1100L — maximum-capacity option for large irrigation layouts and serious water storage requirements

🌿 Ideal for Hydroponic and Nutrient Reservoirs

Plant It Flexible Tanks can be used as water or nutrient reservoirs for hydroponic systems, drip irrigation, AutoPot-style layouts, IWS systems and general grow room watering. Their collapsible format makes them especially useful where a large rigid tank would be difficult to carry into place.

  • Suitable for hydroponic systems
  • Useful as a nutrient solution reservoir
  • Practical for drip feed and irrigation systems

For compatible system ranges, browse Drip Feed Systems, AutoPot Systems and Spares and IWS Kits and Spares.

🌧️ Suitable for Garden Water Storage and Rainwater Collection

As well as hydroponic use, Plant It Flexible Tanks are useful for general garden water storage and rainwater collection. They can be positioned where water is needed most and used to support regular watering, greenhouse irrigation, hand watering and reservoir top-ups.

  • Useful for collecting rainwater run-off
  • Suitable for garden and greenhouse watering
  • Helps reduce reliance on mains water for plant care

🔧 Easy to Store When Not in Use

One of the main benefits of a flexible tank is that it can be stored away more easily than a rigid water butt or reservoir. This makes Plant It Flexible Tanks useful for growers who need seasonal storage, temporary water capacity or flexible grow room layouts.

  • Packs away more easily than rigid tanks
  • Easier to move through narrow access points
  • Useful for changing or temporary grow spaces

🚿 Useful for Larger Watering and Feeding Routines

Choosing the right tank size can make watering and feeding routines much more efficient. Larger capacities reduce the need for constant refilling, while smaller tanks are easier to manage in compact spaces.

  • Helps reduce frequent refilling
  • Useful for mixing larger batches of nutrient solution
  • Practical for gardens, greenhouses and grow room feeding routines

For accurate feed preparation, use a Measuring Jug, Measuring Syringe or 5ml Pipette. For plant feeding products, browse Nutrients and pH Management.
