What Every Plant Needs

Any plant, whether it’s soil-based or hydroponic, requires six basic elements to flourish. The first three plant nutrients, carbon, hydrogen and oxygen, are delivered in the form of air and water. The other advanced nutrients – nitrogen, phosphorus and potassium – are pulled from the soil, or in the case of hydroponics, provided by your fertilizers. Supplements for your hydroponics can further boost these key hydro nutrients.

When plants need to create new tissue, they rely on nitrogen (chemical symbol N). In nature, nitrogen can be hard to find, so plants have adapted to absorb it whenever it’s available. This behavior, unfortunately, may cause a plant to grow plenty of leaves, but see limited fruiting or flowering. With so much nitrogen available to absorb, it fails to completely activate its blooming stage.


This mineral fuels root growth, gets flowers to bud, boosts vitality and enlarges seeds. To provide these benefits, phosphorus (chemical symbol P) is used to transfer energy from one part of the plant to the other. Organic matter and soil-based organisms increase the phosphorus available to plants.


Plants make carbohydrates, the edible plant parts we enjoy so much, with potassium (chemical symbol K). At the same time, this mineral invigorates the plant, helps to regulate its metabolic activities and provides it with disease and pest resistance. Potassium is widely found in natural settings and gardeners often provide extra potassium in the form of compost.

Additional Hydroponic Nutrients You May Need

Many plants need additional minerals, or micronutrients, to properly grow, but in far smaller amounts than “the big six.” These organic nutrients can be provided by a number of sources for use in a hydroponics nutrient solution. They are:

  • Boron
  • Calcium
  • Chlorine
  • Copper
  • Iron
  • Manganese
  • Magnesium
  • Molybdenum
  • Sulfur
  • Zinc
