There are several extensive differences that set us apart from a conventional brewer. The first important element to the Organics Alive Bio-Extractor is the oxygen diffuser. The diffuser does not allow biology or biofilms to stick or attach. Any diffuser with a porous nature, such as a rock stone or a simple air tube, will hinder biological growth and multiplication. Our diffuser pushes air at 6ppm oxygen diffusion, creating course and fine bubbles made to agitate and extract the biology from the cultured Mix-Kit and rapidly multiply aerobic beneficial microorganisms. The patented chimney holds the Mix-Kit at a specifically tested and engineered level for perfect cavitation. This allows an extraction and feeding process which multiplies the biology 9 billion times in 24 hours. The tea becomes extremely active, alive, and concentrated. The amount of biology in one gallon of brew equates to 2000Ibs of Organics Alive worm castings. The Organics Alive Bio-Extractor is very easy to clean, runs efficiently and quietly. It is designed to be brewed at room temperature in your home or garden.
