Please note: You may notice that the consistency of our nutrients is close to that of “kinetic sand” and maybe appear moist on first glance. Please be assured that this is completely normal, and will not affect the solubility, nor performance of your product. This consistency is due to the sheer complexity of our nutrient blends, which is 100% geared toward growing the strongest and most quality harvest possible.
