Contains phosphorous (p) and potassium (K), which dramatically stimulates robust flowering in plants.  Made of highly concentrated minerals that promote massive flower development.

Stimulates Flower Development

When your plants begin flowering they crave more Phosphorous to accelerate and enhance floral development. They also need more Potassium to stimulate increased photosynthesis, regulate water and nutrient movement, and to encourage optimal sugar production to maintain robust flowering. PK Heavy boosts your plants metabolism, enhancing your plants ability to create massive dense flowers.

Bigger is Better

PK Heavy delivers those massive dense flowers that all gardeners want. By supplying plant available Phosphorous (P) and Potassium (K), PK Heavy effectively promotes aggressive flowering to bring you an abundant yield. Your plants will concentrate on flowering without wasting precious energy on vegetative leaf growth.
