Mills Nutrients C4 is a bio-stimulant supplement that’s used during mid to late bloom to help encourage plants to produce, not only healthy fruits and flowers, but to also to push their size, density and final weight, giving the grower yields they never thought we’re possible.

Described as a bloom burst, Mills Nutrients C4 will also aid the production of the plants natural oils as well as sugar production, giving sweeter and more vibrant fruits. C4 can also be used in all grow systems, so if you grow in hydro, soil or coco, C4 can be added to your nutrient solution to give you amazing results at harvest time.


  • 0.5 – 1ml per litre during weeks 3 to 6 of the bloom cycle
  • If using C4 alongside Sugar Rush, use them on alternative feeds during weeks 3 to 8 of the bloom cycle.
