Essential Elements required for Hydroponic Farming

Cannabis farmers can benefit from the hydroponic farming system if they bring together necessary components for better hydroponic farming practices. This farming technique replaces soil, which is needed to make plant to grow with water and a medium.

For hydroponic cannabis farming to be successful, three key elements are needed.


All plants need light to produce the energy required to grow through the process of photosynthesis. It is the process whereby plants convert light energy into chemical energy necessary to provide their food. Therefore light is an essential element needed in the hydroponic system to be successful. When setting up a hydroponic system, one of the components is a lamp system to produce the light required for the plant to use for its photosynthesis. It is the light component that makes it possible to grow cannabis in your living room, closet or any space in your home that is available for farming cannabis.


Water is essential in hydroponic farming just as it is crucial in traditional agriculture. Water serves as the medium through which plant growing nutrients are introduced into the hydroponic system. The root of the plant connects to the water depending on the hydroponic system in use, either directly or via another medium such as a network of wick or misting as the system dictates.

Water serves as a carrier for micronutrients and nutrients solution including such nutrients as nitrogen, magnesium, potassium and phosphorous. Traditionally, nutrients are found in the soil, and they determine the richness of soil in standard farming practice. Let’s discuss these nutrients briefly:

  •    Nitrogen (N): this nutrient serves various purposes in plant growth. It contains amino acids which are plant protein and helps in the compounds contributing to store energy for use by the plant.
  •    Potassium (K): The quality of the crop is determined by the amount o potassium available to the plant. This includes size, quality, shape, yield, and color. The K nutrient in the water is essential for crop’s structural strength and quality.
  •    Phosphorous (P): It helps root growth, structural strength, and quality of the plant.

Note: it is essential to check the acidity and alkalinity level of the water regularly to get the correct mix of these nutrients.


The third element required for hydroponic farming is air. You know plants also breathe like humans, and it is the air that helps them take in carbon dioxide (CO2) and blend with light to produce sugar and water through the process of photosynthesis. In a hydroponic environment, the air is generated by the fan and the filter system.

These elements are present in the different types of the hydroponic system whether it’s the Wicks, Water Culture, and Drip, NFT or Ebb and Flow system.

Opportunity for cannabis farmers

It is interesting the way the hydroponic system works and more intriguing is the ability of the farmer to control the growth and quality of their crop by ensuring the right mix of nutrients to produce leafy cannabis that is the favorite of many buyers.
