NutSystems MultiDuct Double Long - 6ft is an NFT hydroponic system using a low-lying recirculating reservoir. In the Double Long layout, two 6 ft channels are run end-to-end from a single tank, creating an elongated footprint suited to narrow spaces. The system delivers a thin, continuous film of nutrient solution to bare roots and returns unused solution to the tank, so no timers are required. The 6 ft Double Long configuration uses a 90 L reservoir and typically accommodates about 12–16 plants, with an overall channel footprint around 392 × 118 cm. MultiDuct systems are supplied with channels, tank, pump and fittings, and are designed to run 24/7 with minimal media; SpreaderMat is recommended for even distribution.
