Metrop Calgreen is a super concentrated mineral fertiliser formulated with Calcium, Nitrogen and Magnesium, three key elements for most fast-growing annuals. The extra benefit of using Calgreen is that it increases the size and strength of the plant's cell walls, which boosts the plant’s protection levels against many fungi and microbe illnesses.

Like all Metrop fertilisers, Calgreen calcium is produced from high-quality raw materials and requires less ml/L to do the same job. Be careful not to overdose!
