The Bato Hydro Trough is suitable for hydro cultivation systems with constant water reservoirs. The trough has a highly efficient internal drain water discharge system: by installation two assembled Bato knees, the drain water goes from the lowest level of the trough and will be discharged into the central drain pipe. By doing this, the water reservoir is constantly replenished and accumulation is prevented.The Hydro Trough in combination with the Drain pipe Ø 50 mm is an easy, replaceable growing system. The drain water pipe is available in lengths of 5.5 metres. The Bato Trough is available in two types: the Hydro Trough with a volume of 11 litres and a Mini Hydro Trough with a volume of 10 litres.
