JaggarCross Dutch Blend Fertilizer – One-Part Hydroponic Formula (11-11-18)

Professional One-Part Hydroponic Fertilizer for Consistent Growth from Veg to Bloom

JaggarCross Dutch Blend Fertilizer is a professional-grade, one-part soluble nutrient formula inspired by commercial hydroponic production methods used in northern Holland. Developed by expert grower Xavier Loubresse, this streamlined fertilizer is designed to deliver consistent, high-performance results from vegetative growth through flowering.

With an NPK ratio of 11-11-18, this complete formula includes Calcium and Magnesium along with a carefully balanced micronutrient profile. It is high in nitrate nitrogen, the preferred nitrogen form for many crops, and features elevated potassium levels to support strong flowering and overall plant performance.

Unlike traditional multi-part systems, Dutch Blend is designed to be used at the same rate throughout the entire growth cycle, helping reduce plant stress caused by fluctuating EC levels. The higher potassium content allows plants to build internal reserves prior to flowering, supporting consistent performance during peak demand.

This formula contains no added organics, allowing growers to achieve predictable results based solely on mineral nutrition or customize their program by adding supplements as desired.

Delivered as a dry, fully soluble blend, Dutch Blend offers long shelf life, simplified mixing, and reduced shipping costs compared to liquid fertilizers.
