Product Details

A great tonic to promote strong plant growth, and disease- and pest-resistance.

Adding this soluble kelp can help maintain the balance in your aquaponics ecosystem.

  • Stimulates microbial activity - a huge plus for aquaponics!
  • Provides natural growth hormones, trace elements and amino acids
  • Readily absorbed by the plants
  • Enhances flowering & fruiting
  • Aids plant recovery from stress

Suitable for organic farms - Allowed Input 456AI.

This is a potent organic seaweed extract, concentrated into a 100%-soluble powder.  

1 teaspoon per 1000 L of fish-tank water is all you need, so a little goes a long way.  Simply dissolve it into some water and add it to the media-bed inlet that is furthest from the fish tank.  This helps the kelp percolate thoroughly through the system, bringing its benefits to every bed and plant.  (Do not add it directly to the fish tank.)

You can also use it as a foliar spray.  (Test-spray sensitive plants before commiting to this type of application.)

Typical analysis (W/W)

  • Nitrogen (N) (as organic) - 1.17%
  • Phosphorus (P) (water soluble) - 0.23%
  • Potassium (K) (as organic) - 19.12%
  • Sulfur (S) - 1.80%
  • Magnesium (Mg) - 0.37%
  • Calcium (Ca) - 0.34%
  • Boron (B) - 135 mg/kg
  • Iron (Fe) - 471 mg/kg

 We apply this kelp to our systems weekly, or as the plants need it. 

NOT FOR HUMAN CONSUMPTION.  Keep out of reach of children.
