Coir Feed® is a finely-filtered liquid nutrient package containing a full suite of high quality, pharmaceutical grade, macro and micro elements specifically designed for high-performance hydroponics growing with coconut coir media in drain to waste and ebb and flow systems.  Coir Feed® is specially balanced with extra calcium and magnesium and slightly less potassium to accommodate coconut coir’s CEC (cation exchange capacity) properties.  The Coir Feed® Grow formulation includes select multiple essential carbohydrates, vitamins, L-amino acids, SAR-inducing (systemic acquired resistance) and essential oil boosting precursors as well as organic chelators for maximum elemental uptake.

The Coir Feed® hydroponic nutrient elemental ratio has been calculated to synergistically include use with Commercial Edition® Sila-Guard®, Cal-Mag®, Trich-XL®, Zone® and Saturator® as a balanced, high-purity, complete plant nutrition formulation guaranteeing a maximum yield, optimal plant health, growth and increased trichome production.  No need for anything els

Usage & Mixing Instructions:

See Usage Instructions & Tips for in-depth root & foliar feed directions and advanced growing advice, and Feed Charts for recommended nutrient and additive dilution rates.  Shake before use.  Never mix undiluted nutrients or additives together as precipitation (fallout) will occur rendering some nutritive elements unavailable to plants potentially creating deficiencies.  Dutch Master® converts EC to ppm using x0.50 calculation.  See PPM vs EC in the growers guide. Reduce Cal-Mag® by 1mL per gal/4L for every 200ppm/0.4EC found in hard well or tap water.

Add separately to water while stirring, beginning with Sila-Guard®, then Cal-Mag®, followed by Micro, Grow, Bloom, Trich-XL®, Zone® then Saturator® last until you reach desired EC/ppm - measuring preferably using a calibrated meter.  To increase nutrient EC/ppm strength, increase dosage volume of Micro, Grow and Bloom maintaining recommended dilution ratios.  To decrease nutrient EC/ppm strength, dilute by adding more water.  Finally, check pH and adjust accordingly.

Dutch Master® recommends maintaining Coir Feed® nutrient solution pH between 5.6-6.2.  When making a fresh nutrient solution, adjust the pH to 5.6 as pH may rise over time.  If the pH of your nutrient solution approaches 6.2 and it’s not time to drain and refresh the entire nutrient solution in the system, slowly add a little Dutch Master® Commercial Edition® pH Down while stirring and checking with a calibrated pH meter to achieve 5.6pH.  Remember, adding pH Down is also adding phosphorus so be diligent with its use.  For the longest product shelf life, store nutrients and additives with a sealed cap in a cool, dark, dry area.
