N-TECH 45 is a formulated nutritional product and not just a simple mixture of raw materials, as are most of NPK fertilizers in powder form. N-TECH 45 has an uniform and simultaneous solubility of all the nutrients, during use, while avoiding sedimentation in the storage containers of the nutrient solution. In contrast, common NPK water soluble powder fertilizers, which are produced through a mixture of raw materials, have increase variability in grain size that results in a non-uniform dilution of nutrients, since the smallest grains are dissolved firstly.
