Mills C4 is a sophisticated bloom stimulator containing carbohydrates, macro and micronutrients and trace minerals guaranteed to give the grower heavier and higher quality yields. C4 also helps facilitate the triggering and maturation of complex essential oils appropriate for the early and mid-stages of flower development.

When used with Basis A&B it alters the NPK to have higher phosphorus and potassium levels which helps initiate the growth of fruits and flowers. C4 is predominately organic and has zero biological activity, allowing it to work in conjunction with beneficial biologics to feed tender flower sites and maintain overall health of the plant.
