Multi Zen is an extremely beneficial additive to incorporate into your arsenal. One of the most concentrated enzyme products on the market, Multi Zen boosts overall plant immunity by breaking down dead root material and converting it into nutrients the plant can absorb -- but that's just one aspect of its benefits. Breaking down this dead root material prevents bacterial and fungal diseases, keeping your root zone happy and healthy. Other enzymes included in each bottle convert nutrients into more readily available "chunks", boosting the rate of nutrient uptake and ensuring you're getting every benefit from the other nutrients you're feeding your plants.
