Hydroponic nutrients

Just like humans, plants do best when they’re given just the right mix of nutrients.  You can purchase pre-made nutrients or you can make your own, custom tailored to the needs of the plants you’re growing.

There are three main nutrients plants need – nitrogen, phosphorus and potassium.  Nitrogen is an essential ingredient in building plant cells and helping the plant grow.  Phosphorus promotes healthy root growth and is also used by the plant to create flowers and fruits.  Potassium is a nutrient used to process energy and is vital for overall plant health.

Besides the big three, there are many trace nutrients that are needed by plants.  Some of the more important ones are

  • Sulphur – helps the plant make energy and increases the effectiveness of phosphorus.
  • Iron – needed to produce chlorophyll.
  • Manganese – helps the plant absorb nitrogen and also helps transfer energy through the plant.
  • Zinc – also essential for energy transfer.
  • Copper – used for producing chlorophyll.
  • Boron – required in small amounts, but exactly what the plants use it for is not known.
  • Magnesium – helps distribute phosphorus through the plant.
  • Calcium – promotes root growth and helps plants absorb potassium.

If you’re just starting out, it’s best to stick with a nutrient kit, such as the FloraSeries Performance Pack. This kit provides all the different nutrients you’ll need to keep your plants healthy and triving. Depending on the type of plants you’re growing, some additional nutrients can help grow larger, tastier vegetables.
