All our fertilisers provide nutrients for plants to grow and thrive. They enrich your plant with the nutrients it needs, for a specific period of its life cycle. Fertilisers make your crops grow faster and larger, so yields will be increased. We divide the type of nutrients into different levels. The primary nutrients are nitrogen (N), phosphorus (P) and potassium (K). These three nutrients improve the growth and productiveness of the plant. Secondary nutrients are for example calcium (Ca), magnesium (Mg) and sulphur (S). There are further micro nutrients that complete the composition of each individual fertiliser. The Hesi fertilisers contain several different nutrients, blended to the perfect mix for your plants! Use our boosters alongside your fertiliser feed, to improve the metabolism and resistance of your plant.
