Advanced Tips Choosing a Hydroponic System
Hydroponics is a soilless growing method where plants receive a water-based nutrient solution,[1] giving growers precise control over the growing environment and inputs like water, nutrients and oxygen. Several hydroponic systems—varying in size, complexity and efficiency—are available. These setups can be:
Open or closed:
Open systems discharge the nutrient solution after use.
Closed systems recirculate the nutrient solution for reuse.
Active or passive:
Active systems use pumps to deliver the nutrient solution to plants.
Passive (e.g., wick) systems give roots …
