Description ISN Microbe Boost is an army of organic probiotics for your plant. By using our Microbes from week 1 you will rapidly start to see root growth. This is the perfect start of growing healthy strong plants with big yields at the end. Our ISN Microbe Boost works by ‘softening’ all the inorganic salts in the roots and flushing them out. You should never have to worry about salt build up again! It also consumes the dead root mass while increasing the dissolved oxygen levels in the root zone, which in-turn produces healthy root mass. The Microbes also amazingly convert waste products into a healthy organic nourishment for the plant. ISN Microbes can even be used as a foliar spray to trigger healthy leaf growth, increased flower sights, boost of yield sizes and fight off any unwanted pests.
