Description
Aimed directly at the soil growing market, Hesi Phosphorus Plus is a PK booster for plants to help increase flower and fruit formation.
During the flowering period, plants are at the peak of their lifecycle and therefore have a greater need for certain elements such as phosphorus and potassium.
Phosphorus is needed to help with early growth as well as speeding up blooming and fruit growth. Potassium complements this by increasing the development of carbohydrates, starches and sugars which the plant uses to increase fruit production.
Hesi Phosphorus Plus is very highly recommended for anyone using the Hesi Soil range of nutrients.
