What is Fertigation?
Probably the simplest form of hydroponics, fertigation focuses on delivering nutrient-filled water to plants that are growing in a medium such as coconut coir. Basically, the liquid nutrients are delivered into the medium where they are absorbed quickly by the plant roots.
Drip systems are among the most common of the fertigation setups. These usually involve laying easy-to-install PVC pipe or hoses that branch out from a central reservoir. Each pipe leads to an individual plant.
Nurseries commonly use this type of hydroponics to fuel the growth of potted plants. Because of its simplicity, a fertigation system can also be scaled progressively upward to feed a large number of plants.
