Compost tea is an aerated solution that is teeming with billions of beneficial microorganisms that can be applied directly to the leaf surface of a plant as a foliar spray or used as a soil drench to improve root systems. It is made by extracting and replicating the beneficial biology and diversity in compost into a liquid form. Compost tea works by putting the aerobic beneficial biological diversity that your plant needs onto the leaf surface of the plant or the soil. You can enjoy the proven benefits of compost now in a liquid form. Many home gardeners and farmers use compost tea as an organic fertilizer to restore a much needed diversity and population of beneficial bacteria, fungi, and protozoa back into the soil foodweb. Others use compost tea as a foliar spray to reduce disease. Whateveryour particular needs, compost tea will help you on the path towards a healthier, natural, organic garden!

We have the only lab tested, 12-hour brewing system in the world. Not only is it recommended by biologists and horticulturalists and being used a multiple universities, but it has also been lab tested to provide excellent conditions for microbial growth!

We have Pro Kits for every size brewer on the market, ranging from 5 gallons to 1,000 gallons. These kits are pre-measured, biologically inoculated and prepared fresh with every order so all you need to do is put it into your compost tea brewer and go! We have received a lot of positive feed back in regards to disease suppression and overall plant health.

Give your plants the resources they need to survive in today’s environment. Our soils have become compacted and polluted through urban growth and the use of chemical pesticides, herbicides, and fertilizers. Within the soil food web, many different microorganisms work together and play a vital role in keeping the soil healthy. Compost tea puts the “good” biology back onto the plants and into our soil!

“The KIS brewers are extremely easy to set up and use, very easy to clean, and make great teas by extracting all the species of bacteria, fungi, protozoa, and nematodes present in the compost into the tea. Using the right resources, the KIS brewer can get fantastic fungal biomass growing in their tea maker. Using the KIS starter foods and compost, we have never seen the KIS brewer have a problem maintaining aeration. Even if “poor compost” has been used, where E.coli and other pathogens were in high numbers, these problem organisms have been dropped to less than detectable levels by the proper use of this machine.”

“From the instant I got my KIS brewer, I knew it was going to be fun. The instructions were so simple that I set it up in about three minutes and turned it on before I went to bed. I used the tea in our greenhouse the very next morning (14 hours later instead of 12, but that was only because I slept in!). It was a fine looking brew with a great smell, good feel, and excellent color. I was quite sure my plants would appreciate it and I couldn’t wait until the snow melted and I could get our and use the KIS-made compost tea on our gardens and lawns.

Am I pleased with my KIS? Just try and take it away from me.

Thanks for this important machine. It will change the world. I know it has changed the way we garden here in Alaska.”
