GT 205 Hydroponic System

NutSystems GT 205 is the smallest Gro-Tank NFT system in the GT range. It combines a 20‑litre integrated reservoir with a shallow sloped tray above. A Micro‑Jet MC320 pump continuously delivers a thin film of nutrient solution across the bare roots, which drains back into the tank for recirculation. The system runs 24/7 with minimal growing media, ensuring high oxygen availability at the root zone and straightforward upkeep. Typical capacity is one to three plants, and the compact footprint (around 70 × 40 × 20 cm) suits small tents or tight spaces. Kits commonly include the tank, NFT tray, silver top plate, spreader mat and pump. GT systems were first launched by NUT Systems in 1976 and remain a proven NFT format.
