Flowerfield Enterprises is pleased to offer THE KIS 5-GALLON system designed by Leon Hussey. This system was designed for the home gardener or grower. You supply the bucket, we provide the rest: a powerful pump for excellent aeration, a diffusion coil for producing the bubbles, all necessary tubing and connections. This system has undergone extensive testing to ensure that it multiplies all of the organisms you want in a tea. . bacteria, fungi, and protozoa. Beneficial nematodes aren't likely to reproduce during the 12-hour residence time which this brewer is capable of, but repeated tests show that all the other organisms do. Enough good quality compost and food sources come with the unit to make 3 batches of tea. Order more compost bags inexpensively, or use your own. (One advantage of using this combination of compost and worm castings is that it has already been tested and known to provide a good inoculum of the organisms you want.)
