GT CSS is a nutrient concentrate with added rooting hormone. It is formulated for use on plant cuttings, as the added rooting hormone helps to rapidly develop roots from the cutting. Once roots are present, GT CSS will feed your cuttings with its added complete and balanced mineral fertiliser, encouraging vigorous root and vegetative growth. 

Cuttings should be initially watered with GT CSS diluted at a rate of 5 ml per litre of water, and the strength should be increased to a maximum dilution rate of 10ml per litre as the cutting becomes more established.
