ROCK NITRO 

Rock Nitro is a concentrated nitrogen supplement that will accelerate plant growth, driving juvenile plants into maturity. Calcium, another component of Rock Nitro is an important constituent for the growth of strong cell walls which in turn helps to build strong stems.

Rock Nitro will work in all mediums but is especially suited for coco coir which tends to reduce the efficiency of nitrogen solutions. To encourage rapid growth and shorten grow times to maturity, choose Rock Nitro.
