- Dig down in your compost pile or bin till you hit some well composted material, but avoid compost that contains animal manure.
- Fill a container with 1 part compost and 4 parts de-chlorinated water or, ideally, collected rainwater. Optionally, you can add something sweet and sugary to the mixture such as molasses, maple syrup, cane syrup or fruit juice, to aid the growth of the bacteria in the compost tea.
- Use an air pump setup, like you would find in an aquarium or something more powerful, to oxygenate the brown swamp water sitting in your container.
- Allow your compost tea mixture to brew for 1 to 3 days, out of direct sunlight. The finished tea will look like coffee and smell sweet and earthy. Strain the mixture to remove the particles of compost out of the liquid. Keep the air pump running or refrigerate until you are ready to use it.
- Your compost tea can now be used to deliver nutrients, hydration and microbes directly to the plants in your CubeFarm. Additionally, it can be sprayed onto your plants to deliver nutrients directly to the foliage.
