  • Fill your reservoir with clean water before administering any nutrient or additive.
  • Make sure that the water level in your reservoir is sufficient 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.
  • 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.

Please avoid storing in direct sunlight and protect from freezing.
