The important thing about PK enrichment is that it must be available to the plant at an elemental ratio of 9-18. This means by the weight, and not by volume of any given solution. Other PK bloom boosters available often have ratios calculated by volume and not weight. This can be misleading as once the actual elemental ratio is calculated it is often way outside the optimum range of availability possible, and needed, for your plants to achieve their potential.
More than just a PK…the raw material in this product are a complex organic formula with added sulphur that increases natural oils and overall quality.
