Chase SM3 is a natural plant growth stimulant made from seaweed responsibly harvested from the shores of the British Isles. It enables edibles to make efficient use of nutrients, leading to improved yield, taste and colour, and increased resistance to pests and diseases, drought and marginal frosts. Chase SM4 is a blend of plant-derived nutrients and Chase seaweed extract. It is a complete organic, animal-free biostimulant and plant food with an NPK analysis of 5-2-5, together with calcium, iron and magnesium and other trace elements, plus the benefits of seaweed. The new Chase SM5 will encourage bigger yields of better tasting crops of tomatoes, sweet peppers, aubergines, cucumbers, strawberries and many other fruiting plants. This month, 10 GYO readers have the chance to each win a set consisting of a litre bottle of SM3, SM4 and SM5 formulas.
