Nutrients and Additives and Green Houses Benefits

Nutrition management is at the core of a good hydroponic system as it lacks soil and the natural elements that come with it. It is essential for every grower to understand the basic plant nutrient requirements and provide good hydroponic nutrients on a scheduled basis. Plants usually need 16 different elements in nutrition of which hydrogen, oxygen and carbon are available in air and water. The rest need to be supplied in different ratios. Primary macronutrients are the most important ones that are needed in larger ratios than the rest. They include Nitrogen, Phosphorous and Potassium (NPK). Secondary nutrients are calcium, magnesium and sulphur while micro nutrients include boron, chlorine, copper, iron, manganese. Molybdenum and zinc. Each of the elements has a specific role to play in the plants’ life cycle.
