Chempak® Fully Balanced Feed - Formula 3

Multi purpose balanced plant food formula for all house and garden plants

The soluble fertiliser used by professionals and leading growers. All Chempak Soluble Plant Foods contain seven essential trace elements, far more than ordinary soluble fertiliser. These trace elements are absolutely necessary to plant growth and serious disorders can occur if any are absent. They are fully soluble which means they start to work instantly. Chempak Formula 3 has identical proportions of the primary nutrients - nitrogen, phosphate and potash, which make it perfect for all plants all year round.
