Pharmgrade SmartPhos is a special blend of nitrogen and phosphate that has been extensively chelated for maximum uptake by the plant. Because of this chelation, more phosphate becomes accessible, therefore reducing tie-up of nutrient.
SmartPhos also contains high amounts of humic and fulvic acids as well as a high amount of microbes and mycorrhizae for added chelation and root uptake.
This blending process (also known as Hybrid Fertilizer Technology™) provides the necessary nutrients you need to promote root growth and leafing in your crops.
