MicrobeZen is a diverse culture of anaerobic and facultative bacteria capable of unlocking nutrients bound up in organic matter within your garden soil. It can be used to break down old root matter in the soil between crop runs, and used during growth and flowering stages to accelerate nutrient cycling and plant growth. MicrobeZen can be added to compost tea regularly as an after-brew spike to increase the biodiversity of your tea brew. This product is made in house and tested regularly for top of the line quality.
