Mayan MicroZyme is a bacterial- enzymatic concentrate full of microorganisms that can increase fertility while providing vital nutrients to all types of plants and crops. The micro-organisms present in Mayan MicroZyme (MMZ) mineralize nutrients, produce and regulate nitrogen, build organic matter in your soil, and can improve fertility and fruit yields by increasing nutrient uptake and availability. The micro-organisms in Mayan MicroZyme are dormant with a long shelf life because of the micro- encapsulating solution. When the concentrate is diluted in water and aerated, the micro- encapsulation dissolves and the micro-organism populations become active and increase in number. When brewed into a rich tea the Mayan MicroZyme cannot be matched by competing products. Due to the nature of this... Less

Vibrant greens and vigorous growth are what to expect with Verde. Used as a foliar or as a growth catalyst for all your favorite plants, Verde can initiate rapid growth for superior internal structures and lifelong plant health.
