Learning how to brew compost tea is a simple one. We use just a few simple items in the Lab to build an aeration system that not only extracts the valuable nutrients but also the bacteria and fungi. The added bonus is that the process also allows the bacteria to bloom, creating greater numbers in the colony.
Equipment for Brewing Compost Tea
- 5 gallon bucket
- S hook
- Dechlorinated water
- Aeration pump
- Diffusion stones
- Flexible tubing
- Molasses
- Cheesecloth or burlap
- Zip tie
- Finished compost or worm castings
The Process
The process is simple. The water captures the nutrients and microbes that leach from the compost as the solution is churned by countless bubbles emitted from the diffuser stones. Over 24 hours, and fed by the molasses, the bacteria blooms into a population of millions. The extracted nutrients and microbes are then diluted and applied to the plants or soil as desired.
Video: Step by Step Instructions for Making Compost Tea
Our friends at Bright Agrotech, the folks behind the ZipGrow technology that we use in our hydroponics station, spent a day in our flagship Lab in Buffalo, WY. They wanted to see our systems in person, and this video showing how to make compost tea was one of the parting gifts. We had a blast shooting this with them and I think you’ll find it’s very informative.
