High quality plant nutrients are an essential component to plant health. In hydroponics, nutrients are fed to plants through the nutrient solution. They consist of elements that plants utilize to produce sugars and carbohydrates that in turn are changed into proteins and other complex substances. This process is an essential factor in plant growth.
A high-quality nutrient will have the right balance of macro and micro elements. The elements in nutrients can be mineral or biological. Some nutrients will contain additional ingredients that promote plant health or increase yield such as sugar, kelp, enzymes and fungi.
