Growth Science’s Rock Solid is a powerful, cost-effective bloom booster for the flowering cycle that doubles as a P/K booster to provide additional phosphorus and potassium in bloom. Rock Solid also incorporates proprietary plant extracts in this blend to aid in flower site development. These added components facilitate improved overall harvest yields as well as maximized resin and aromatic production.

Why use Rock Solid?

The secret to Rock Solid’s success lies in its ability to improve plant cell efficiency, promoting enhanced growth, yields, flowering site development, sugar and enzyme development, uptake of water and nutrients, and photosynthetic ability. The combination of these factors makes Rock Solid one of the most accessible and easy to use comprehensive bloom boosters available with results that parallel or exceed many other competitor products.
