Mills Nutrients is designed from the ground up for performance, versatility, and ease of use. Made in the Dutch tradition of a two part nutrient along with additives that provide plants with everything they need and nothing they don’t.

Mills is a pioneer in the field of bio-mineral plant nutrients, utilising the best sources to optimise growth rates, yield, flavour, and aroma. Years of testing in soil and coco-coir, in professional greenhouses and with hobbyist growers alike have led to a complete, easy to use line of products

And it's all there in five easy to use components;
Mills have focused on blending all the plant's needs into five components instead of expanding the range into a complicated and expensive multitude of bottles.

Mills Nutrients are known for their ease of use, stability, cleanliness and cost effectiveness.
It's also why the phrase "Mills Pays the Bills" is common among cultivation communities around the globe.
