PK 13-14 is a high quality pure Phosphorus and Potassium compound, which is usually added during the flowering period. It is a highly concentrated formulation containing a balanced blend of the pure elements Phosphorus and Potassium for the best flowering results.

This unique combination of elements could be called the super-flowerer that develops heavier, tighter and smoother buds faster.

PK 13-14 has been tested by professional growers around the world to increase flower weight significantly, harvest after harvest.
