Cleaning sprayer and disposing of brewer residue is simple and safe for you and your plants. Our microbe soil life tea can not harm you or your plants. The same can not be said about compost teas as they inherently carry risks from the good, bad and the ugly bacterias often found in the mediums used to try to extract beneficial soil life from. Unlike compost brewing our microbe tea soil life brewer provides all the beneficial bacterias as a resource which it propagates in the brewing process, into the billions, levels compost teas can not achieve.
