Precision Reservoirs for NFT Systems
GT Systems’ Tanks are the foundation of every GT setup — serving as the nutrient solution reservoir that feeds your plants’ bare roots on the tray above. Designed for performance, efficiency, and simplicity, these tanks keep your nutrient solution perfectly recirculating for strong, healthy growth.
Whatever the roots don’t absorb flows gently back down the tray slope into the tank, ensuring your solution is constantly recycled, oxygenated, and nutrient-rich.
Available Models and Capacities
Each tank is built from high-quality, durable materials and designed for compatibility with all GT NFT trays and Multi-Duct systems. Choose the perfect size for your growing area:
| Model | Dimensions (cm) | Capacity (Litres) | Notes |
|---|---|---|---|
| GT205 | 71 × 40 × 20 | 20 L | Compact and efficient — ideal for small setups or propagation. |
| GT424 | 101 × 50 × 20 | 45 L | Perfect for medium spaces with moderate plant counts. |
| GT604 | 158 × 52 × 20 | 60 L | Balanced option for efficient nutrient distribution. |
| GT901 / GT090 | 90 × 90 × 30 | 70 L | Designed for 1 m² grow tents — a popular all-rounder. |
| GT100 | 108 × 112 × 20 | 100 L | Larger footprint and higher capacity for extended cycles. |
| Multi-Duct 125L | 119 × 67 × 26 | 125 L | For longer channels and extended NFT setups. |
| Multi-Duct 190L | 211 × 60 × 23 | 190 L | Ideal for large or multi-tray NFT configurations. |
Each reservoir offers excellent volume-to-height ratio, ensuring smooth nutrient recirculation and low-profile operation — ideal for spaces with limited headroom.
How It Works
Each GT Tank acts as the heart of your system:
-
Nutrient Circulation: Solution is pumped from the tank to the sloping tray above, passing over the roots before returning to the tank.
-
Continuous Oxygenation: Air tubing keeps the solution oxygen-rich, maintaining optimal conditions for root health and rapid growth.
-
Media Efficiency: Plants grow with bare roots directly over the film of nutrient solution — eliminating the need for excessive growing media and reducing waste.
The result? Faster growth, cleaner roots, and significantly higher yields.
Key Benefits
-
Proven Results: Achieve up to 3× greater yield than conventional growing methods.
-
Healthier Plants: Roots are never over- or under-watered, and no salt build-up occurs in the root zone.
-
Compact Design: Just 20–30 cm tall — ideal for smaller grow spaces or low headroom areas.
-
Eco-Efficient: Minimal media use means reduced disease risk and less waste to dispose of.
-
Reliable Construction: Built for durability and seamless integration with GT System trays and components.
Key Advantages of Growing in Nutrient Film Technique (NFT)
The Nutrient Film Technique (NFT) offers exceptional efficiency, accelerated plant development, and excellent space optimisation — particularly suited to indoor and vertical growing environments.
-
High Resource Efficiency: The closed-loop design recirculates nutrient solution, reducing water usage by up to 90% and minimising fertiliser waste.
-
Faster Growth & Higher Yields: Continuous access to oxygen, nutrients, and water ensures faster growth cycles and higher yields.
-
Optimal Root Oxygenation: The thin nutrient film allows roots to breathe freely, preventing rot and promoting healthy root systems.
-
Space Optimisation & Scalability: Low-profile design suits both compact setups and large-scale commercial layouts.
-
Easier Disease & Pest Management: The soilless system limits exposure to pests and pathogens, and exposed roots allow quick inspection.
-
Automated & Low Maintenance: Pumps and sensors can monitor pH, EC, and flow automatically — reducing manual labour.
-
Consistent Nutrient Delivery: Uniform nutrient flow maintains stable pH and EC levels across the entire system.
Growers’ Tips
-
Check Roots First: Only add plants once roots are well developed — white roots should be visible around the starter cube.
-
Plant Density: Use roughly one plant per square foot, adjusting by variety and growth habit.
-
Continuous Flow: Keep the pump running 24/7 for constant nutrient and oxygen delivery.
-
Boost Oxygen Uptake: Remove any wrapping from Stonewool cubes or pots to expose roots to air and the nutrient film.
-
Monitor pH and EC: Maintain optimal ranges — pH 5.8–6.0, EC 1.2–2.0, depending on the growth stage.
-
Maintain Temperature: Keep nutrient solution at 18–22 °C for best oxygen levels and root activity. A water chiller is recommended for consistent performance.
-
Stagger Plant Positioning: Offset plants slightly along the tray to ensure even nutrient distribution — preventing the first plant from taking the richest feed.
-
Clean Regularly: Empty and clean trays and tanks every 7–10 days to prevent algae, salt build-up, and system blockages.
Compatibility
GT Systems Tanks are compatible with all GT NFT Gro-Tank trays and Multi-Duct NFT systems. Each tank is crafted from high-grade materials, easy to clean, and designed for years of reliable service.
