Fast growth and strong stems

Everything you need

Nitrogen (N) is used by plants for leaf and shoot growth. Phosphorous (P) is used by plants to help form new roots, make seeds, fruit, flowers, and fight disease. Potassium (K) is used to make strong stems, promoting fast growth, and the movement of water.


What are Micro-Nutrients?

These are essential plant nutrient elements. All plants need these to build and grow and to achieve full balanced plant nutrition. All RocketGro products contain optimum amounts of naturally present micro-nutrients including Magnesium, Sulphur, Copper, Zinc and Nickel.

Copper is essential for strong vitamin A production and protein synthesis. High yields are impossible without Zinc. And Nickel is very important to maintain healthy plant metabolism.
