Back by popular demand, new and improved Commercial Edition® Zone® is a finely-filtered, tested and scientifically proven root zone optimization formula that helps to maintain a healthy, pathogen-free rhizosphere environment for optimal nutritional uptake by the plants roots.  Zone® is designed to control outbreaks of nasty, yield-decreasing and plant-destroying root rot (pythium, phytophthora, fusarium) in your media.  Use as a full-time maintenance dose in all systems (water culture, ebb & flow, top feed, etc.) with all mediums (coir, rockwool, soilless, perlite, hydroton, etc.) or increase dosage strength for existing problematic pathogenic root zone conditions. Important: Do not use Zone with organic nutrients, additives, enzymes, beneficial bacteria or medias that have been amended heavily with organic fertilizers.

The Dutch Master® Commercial Edition® is a range of advanced nutrients and additives suitable for both professional and general hydroponics growers and is proudly manufactured in Chicago U.S.A. under strict licensing exclusively for Dutch Master® Nutrients in an ISO 9001, ISO 13485 (medical manufacturer) and ISO 14001 (green manufacturing practices) certified facility - a world first in the cannabis community!

Usage & Mixing Instructions:

See Usage Instructions & Tips for in-depth root & foliar feed directions and advanced growing tips, and Feed Charts for recommended Zone® dilution rates.  Never mix undiluted nutrients or additives together as precipitation (fallout) will occur rendering some nutritive elements unavailable to plants potentially creating deficiencies.

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.  If you don’t have a TDS meter, be sure to follow our Feed Chart recommended dilution rates beginning with the standard feed chart before progressing confidently to the aggressive feed chart.  Zone should be added to every fresh tank mix and also replenished every 3-5 days, depending on environmental stresses and media used.  The warmer the nutrient solution and or pots, the more often the top up.  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 nutrient feed solution pH for Aqua Feed® and Media Feed® between 5.5-6.1 and Coir Feed® between 5.6-6.2 using Commercial Edition® pH Up or pH Down.  When making a fresh nutrient solution, adjust the pH to the low pH point recommended for your nutrient above, as pH may rise over time.  If the pH of your nutrient solution approaches the high pH point above, 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 or pH indicator strips to achieve the low pH point again.  Remember, adding pH Down is also adding phosphorus, while adding pH Up is also adding potassium so be diligent with its use.  If the pH of your made up nutrient solution shifts drastically in a short period, it is usually a sign that the plant is stressing.  Check for root rot etc.  For the longest product shelf life, store nutrients and additives with a sealed cap in a cool, dark, dry area.
