Nitrozyme is the most complete natural growth product available. It is derived from Ascopyllum Nodosum which is a variety of Seaweed found in the the North Atlantic Ocean and the Norwegian Sea. The natural Cytokinins found in Nitrozyme will help control and regulate germination, root development, nutrient uptake, plant tissue composition as well as flowering, seed and fruit set. Nitrozyme acts by relieving plant stress which in turn provides a more vigorous and healthy plant and ultimately increases yields. Nitrozyme can be used as a foliar spray at the rate of 3ml per litre or in the nutrient tank at the rate of 1ml per litre. Do not foliar feed Nitrozyme if you are adding it to the tank. It is also advisable that Nitrozyme applications cease prior to the flowering period.
