Gro-Tank Multi Duct NFT Complete Kits
Efficient, Proven, and Space-Saving Hydroponic Systems
The Gro-Tank Multi Duct NFT System delivers exceptional growing efficiency, combining simplicity with professional-level performance. Based on the Nutrient Film Technique (NFT) — first launched by NUT Systems in 1976 — this setup continuously supplies plants with a perfectly balanced film of nutrients and oxygen for fast, healthy, and consistent growth.
Expect up to three times greater yields than traditional soil methods, with healthier plants, lower running costs, and minimal maintenance. The low-profile design and long planting channels make the Multi Duct system ideal for maximising output in spaces with limited headroom.
How It Works
In a Gro-Tank NFT System, the nutrient solution is stored in a low-lying tank. Plants sit on a tray above the reservoir, where nutrient solution is gently pumped up and flows over their roots in a thin, oxygen-rich film.
Unused solution drains back into the tank and recirculates, ensuring zero waste and perfect nutrient balance. This bare-root technique eliminates the need for large volumes of growing media — plants receive constant access to water, nutrients, and oxygen, resulting in exceptional growth rates and yields.

Grower’s Tips
-
Check Roots First: Ensure plants are well-rooted before introducing them to the system. Look for healthy white roots around the starter media.
-
Plant Density: Use one plant per square foot as a general guideline, adjusting based on plant variety.
-
Run 24/7: The pump operates continuously — no timers or feeding cycles are needed.
-
Maximise Oxygen: Remove plastic wrapping from cubes or pots to expose roots fully and boost oxygen uptake.
