These are essential components for EBB & Flow Fitting systems, also known as flood and drain setups. They function by intermittently flooding your seedling bench or grow tray with nutrient-rich water, then draining it away to allow the root zone to aerate. This periodic cycling saves both water and fertilizer while providing excellent root oxygenation, which leads to strong, uniform, and healthy seedling development. The EBB & Flow Fitting is widely used in commercial seedling propagation and hydroponic herb production, offering growers an efficient and reliable method to accelerate growth, reduce disease risk, and improve overall crop consistency in controlled environments.
