Get relentless, rapid, uniform growth with Gro from The Source. This beautifully balanced vegetative stage fertiliser provides the exact NPK required for healthy, robust development.

Always sufficient but never excessive, Gro’s all-natural, specially selected ingredients provide a fantastically responsive nutritional regime for all plant types. The fertiliser features amino acids, fulvic acids, humic acids, vitamins, sugars, stress relieving agents, and plant extracted growth hormones that ensure your plants develop fully, remain healthy, and are well suited to heavy harvests.

Gro is a unique and scientifically proven formulation. It has been designed to optimise the performance of AutoPot Watering Systems but is equally effective with all other cultivation methods. Used and tested by the UK’s leading horticultural universities, the fertiliser has produced outstanding results in a wide variety of soil, coco, and hydroponically-grown plants.

Enable your crop to reach its full potential.

Available in 250ml, 1 litre and 5 litre sizes.
