House & Garden Multi Zen is a powerful growth stimulant made up of a wide variety of useful enzymes, which enable your plants to metabolically exchange their sugars. Enzymes are the small catalysts which trigger these processes and keep them in tune with the plant’s growth rate. Some enzymes aid in the breakdown of nutrients making them more readily available, whilst others aid in the plants immune system. There are also particular enzymes which help to dispose of residuals in the plants media. Multi Zen has been favoured by Dutch growers for decades and the results will speak for themselves, to achieve your plants maximum potential, provide them with exactly the enzymes they require.
