Well-fed Plants Are Healthier, More Productive & More Beautiful


At PNC Hydroponics, we provide all range of Fertilizers for your commercial hydroponics operation.


Plant Nutrients


Plants need to be fertilized because most soil does not provide the essential nutrients required for optimum growth. There are six primary nutrients that plants require. Plants get the first three—carbon, hydrogen and oxygen—from air and water. The other three are nitrogen, phosphorus and potassium.


  • Nitrogen helps plants make the proteins they need to produce new tissues. In nature, nitrogen is often in short supply so plants have evolved to take up as much nitrogen as possible, even if it means not taking up other necessary elements. If too much nitrogen is available, the plant may grow abundant foliage but not produce fruit or flowers. Growth may actually be stunted because the plant isn't absorbing enough of the other elements it needs.
  • Phosphorous stimulates root growth, helps the plant set buds and flowers, improves vitality and increases seed size. It does this by helping transfer energy from one part of the plant to another. To absorb phosphorous, most plants require a soil pH of 6.5 to 6.8. Organic matter and the activity of soil organisms also increase the availability of phosphorus.
  • Potassium improves overall vigor of the plant. It helps the plants make carbohydrates and provides disease resistance. It also helps regulate metabolic activities.


There are three additional nutrients that plants need, but in much smaller amounts:


  • Calcium is used by plants in cell membranes, at their growing points and to neutralize toxic materials. In addition, calcium improves soil structure and helps bind organic and inorganic particles together.
  • Magnesium is the only metallic component of chlorophyll. Without it, plants can't process sunlight.
  • Sulfur is a component of many proteins.


Finally, there are eight elements that plants need in tiny amounts. These are called micronutrients and include boron, copper and iron. Healthy soil that is high in organic matter usually contains adequate amounts of each of these micronutrients.


Believe it or not, plants don’t actually need soil to grow.  Soil provides an anchor for plants and nutrition, but those can be provided in other ways.  The plants can root into many substances for the anchor.  Plants are twisted with string and supported to a wire above, rather than a stake in the ground.


By growing in inert growing media, the plant can be provided exactly the optimum food for that crop and stage of life, giving the best flavor and highest yields. Fertilizers offered by PNC Hydroponics are suitable for commercial hydroponics farming, and contain only safe materials.


Additionally, PNC Hydroponics can advise a grower how to recycle nutrient solution recovering fertilizer and water, and feed it again and again to the plant.  This gives the grower significant savings in fertilizer and reduces the negative impact of runoff into the environment.
