Increases Weight and Density

Heavy Bloom™ is designed to increase the size and weight of fruit and flowers. It contains ingredients from natural plant extracts including Amino Acids, Vitamins and Carbohydrates. A mild solution of phosphorus and potassium derived from organic and inorganic sources is also added.

The nutrients in this formula help the plant direct energy to the synthesis of reproductive tissue.
