    Flow rate in gravel NFT hydroponic systems – crucial for optimal system performance

    By Antonius Lecuona|Published On: May 4, 2013|Last Updated: June 10, 2021|Categories: Closed systems, Systems|Tags: closed systems, Flow-rate, Irrigation|

    The correct flow rate of closed hydroponic systems is critical for optimal growth of plants. The flow rates are important for all types of closed hydroponic systems such as pure NFT systems, gravel cultures and ebb-and-flow systems. Inadequate flow rate will result in: Reduced oxygen levels at root surfacesIncreased susceptibility of diseasePlants are under stress [...]
