MaxiGro and MaxiBloom make up Maxi Series, a duo of standalone, one-part powdered formulas with primary, secondary and micronutrients. Because these dry nutrients are designed to dissolve quickly in water, they’re highly concentrated formulas that are easy to use, easy to store and easy to love. And since Maxi Series provides elements essential for proper plant nutrition, it helps grow vigorous plants, strong roots and large flowers for great results.
