Commonly known as: NovaTec Soluble Fertilizer NovaTec N-Max,
Product name: NovaTec® Solub N-Max 19-5-5
NovaTec Solub N-Max 19-5-5 is a high-quality, water-soluble fertiliser designed to support vigorous vegetative growth in leafy indoor plants. It contains a strong nitrogen base (19%), split between 16% ammonium and 3% nitrate nitrogen, which helps boost chlorophyll production and support steady leaf growth without pushing your plant too hard.
What sets N-Max apart is its DMPP nitrification inhibitorthis technology slows down nitrogen conversion in the soil, making it more available to your plants for longer. That means better uptake, less runoff, and a reduced chance of salt build-up in pots.
