It consists of three very important elements that any plant needs, and they are the basic materials for the composition of all fertilizers, which are nitrogen - phosphorus - potassium. Nitrogen increases the growth of leaves and branches, phosphorus encourages the growth of strong and healthy roots, and potassium encourages the growth of flowers and fruits. - In natural agriculture, these elements are present in the soil, but in indoor agriculture (greenhouses and greenhouses) they are quickly absorbed by plants.
