Note: When selecting 2 part nutrients that have a part A and a part B, they MUST be used together for proper performance. Dutch Master Advance is a revolutionary breakthrough in hydroponic plant nutrition. Advance incorporates the first targeted use of Krebs Cycle Metabolites in hydroponic plant nutrition. These Krebs Metabolites (selected amino acids & enzymes etc) are designed to help induce the plant into what is termed short cycling. Short cycling occurs when the correct types of Krebs Metabolites are provided to the plant along with the necessary co enzymes to help the plant complete the Krebs cycle early.
For Dutch Master's Advanced series both the A and B formula are required for proper formulation.
