GT 604 Hydroponic System

GT 604 is NutSystems’ mid-size Gro-Tank NFT hydroponic system designed for efficient, low-media cultivation. The system comprises a shallow reservoir and a sloped tray where a thin film of nutrient solution continuously flows across the roots before recirculating to the tank. The GT 604 provides a 60 litre nutrient capacity and measures roughly 153 × 50 × 20 cm, suiting narrow spaces and supporting about 5–8 plants depending on variety and spacing. It ships as a complete kit with tank, tray, correx top sheet, delivery tube, spreader mat and a submersible pump. The included pump is typically a NEWA MC450, which runs continuously in NFT applications and delivers up to 450 l/h, keeping roots supplied with water, nutrients and oxygen for steady growth.
