The Micro nutrient formula is designed to provide plants with the nutrients they require during their entire life span. It provides a high level of nitrogen as well as potassium and can be used with hydroponic or soil based growing operations. This diverse formula helps assure that none of the elements necessary for plant growth will fall out of solution and lock out.

It can be used on its own but is most effective when used with the Humboldt Nutrients Bloom and Grow solutions. This 3 part system provides plants with the exact nutrients they need throughout their growing cycle. They can be used for flowers, vegetables and herbs and help to provide the best yields on your investment.

Directions for Use:

  • Fill your reservoir with clean water before administering any nutrient or additive.
  • Make sure that the water level in your reservoir is sufficient enough to effectively flood your desired area or table.
  • Potential nutrient lock-up can be avoided by adding the Micro before the Bloom and Grow.
  • Always wash your measuring cup immediately after adding and stirring in each nutrient.
  • Never mix any of these nutrients together in their concentrated form.
  • After adding and stirring in each nutrient, check and adjust the pH to between 5.0 and 6.5. Always check a small sample of water, not the whole reservoir.
  • Not all meters will read identically, Humboldt Nutrients tests are conducted with a Hanna HI9813-0 meter.
  • Keep the water temperature in your reservoir between 66 and 75 degrees F.
  • Drain your reservoir and pumps at least once a week to prevent any salt build-up.
