An organic additive developed from Norwegian sea kelp. Fantastic for keeping plants stout and bushy whilst also helping to reduce stress, increase cell division and, ultimately, yield. Can be used to: Soak seeds, pre-treat rockwool, foliar feeding before taking cuttings and as a regular additive. It's no wonder this is so widely used.

N.B. We DO NOT recommend using Nitrozyme in recirculating systems (NFT, Ebb & Flow etc.) as it will settle and clog the pumps. It is best use as a spray or for soaking media before planting.
