The importance of the right nutrients

Plants need different elements to grow. Three of them can be extracted from water air: carbon, hydrogen and oxygen. What other nutrients do your plants need?

In addition to carbon, hydrogen, and oxygen , your plant needs a number of essential nutrients.

  • The plant cannot complete its life cycle without it.
  • No other element can replace the function of that element.
  • The element is directly related to plant nutrition.


Nitrogen, phosphorus and potassium are the most well-known nutrients that a plant needs. However, he is not yet established as a producer. No, your plant needs different nutrients to grow. Although the plant requires less of these nutrients, they contribute to a good final result of your crop.
