LUMA™ GRO contains a natural fermentation biostimulant, which initiates rapid cell division as it enters the leaf. It stimulates root growth, which leads to a higher nutrient uptake for a healthier plant and also maximizes the use of water. LUMA™ GRO adds organic acid buffers that are important to the plant and is most desirable on grasses that are lightly fertilized during different times of the year and heavily fertilized during other times of the year.
