Terrestrial is a powerful organic fulvic acid formula derived from ancient peat deposits. This nutrient catalyst and plant energizer has shown the ability to improve photosynthesis, increase root mass, increase plant metabolism, stimulate soil microorganisms, and improve plant respiration by increasing oxygen absorbed by root-zone. Due to a high cation exchange capacity, nutrients are bound to these microscopic acids for more direct and immediate uptake. Use Terrestrial in all phases of growth for a hardier, more vibrant, and more productive garden!
