Mills Nutrients
Mills Plant Nutrients is designed, manufactured and bottled entirely in Holland. Mills Plant Nutrients is one of the first to develop bio-mineral plant nutrients utilizing the best of both synthetic and organic sources optimizing growth rates, yield, flavor, and aroma. The success of Mills Plant Nutrients bio mineral formula was realized only after thorough research in the field with both large greenhouse and hobbyist growers alike. Years of trials and tribulations have led to a complete small lineup of products of unprecedented quality providing all the nutritional elements needed; Basis A, Basis B, Start-R, C4, and Ultimate PK. These products unique composition allows growers to use the entire line in all grow mediums. Unlike completely synthetic nutrient lines which can build up in or on top of the soil, Mills Plant Nutrient Bio Mineral formula does not accumulate in the medium giving the grower a tremendous advantage when pushing his/her plants to the limit.

Designed from the ground up for versatility, performance, and ease of use, Mills Nutrients are made in the Dutch tradition of a two-part base along with additives that provide your plants with all you need and nothing you don't. Pioneering the field of bio-mineral plant nutrients, Mills uses both synthetic and organic sources to optimize growth rates, yield, flavor, and aroma. Years of testing in soil, coco-coir, and hydroponic systems; in sterile systems or with beneficial biologics; in professional greenhouses and with hobbyist growers alike have led to a complete, easy to use line of products of unprecedented quality, providing all the nutritional elements your plants need with any growing method.
