Mills Base Nutrients

Mills Basis A & B are the solid foundational nutrients your plants deserve. They have been extensively tested in hydro, soil, and coco.

The versatility of Basis A&B shows best when analyzing Mills additives. In Basis Mills has focused on the nutrients needed in all stages of plant growth.

Mills Additives

The four additives that mills manufactures are Start-R, C-4, Ultimate PK, and Vitalize. Each of these products have a specific purpose that will help increase the value of your garden.


Start-R is a majorly organic, extremely complex bio-stimulant for use with seedlings, vegetatively growing plants and plants in early bloom. It has 2 forms of nitrogen that, when used with Basis A&B, raise the Nitrogen content to a level suitable for seedlings, vegetative growth, and plants in early bloom. It also contains Humic and Fulvic acids, L-amino acids, and a root enhancing Bio-Stimulant derived from auxin- and cytokinin-rich Irish kelp. This leads to the development of a healthy root system in the vegetative and early flower stage. Consequently leading to larger yields at harvest. 


C4 is a bloom stimulator designed to help the plant in delivering carbohydrates, macro and micronutrients, and trace minerals to developing flowers. While simultaneously facilitating the triggering and maturation of complex essential oils appropriate for the early and mid stages of flower development. When you start using C4 you cut off Start-R thus reducing Nitrogen levels while increasing phosphorus and potassium levels. This changes helps initiate growth of fruits and flowers. C4 is mostly organic and has no biological activity, which allows it to work with beneficials to feed flowering sites while maintaining plant health.

Ultimate PK

Ultimate PK is a unique Phosphite based bloom stimulant designed for the last weeks of a plants flowering cycle. Phosphite is a bioavailable form of Phosphate that encourages healthy root systems. It also helps maintain proper nutrient intake and maintains plant vitality late into the flowering cycle. Ultimate PK is the ultimate hardener, bulker, and ripener that will push your production to the limit.


Vitalize was developed in conjunction with Rexil Agro BV, the inventor and leader in Silicic Acid Agro Technology. Years of testing in various environments around the world have led to a uniquely bioavailable form of silicon that can be used as a root soak or foliar spray to improve growth and yield, increase nutrient uptake, and improve pathogen and stress resistance. Vitalize is an additive that you can use no matter what nutrient line you run. Once you try Vitalize you will probably want to give the rest of the line a try. It truly is a product that will make a visible difference in your plants.
