KIS Organics Aerated Compost Tea Brewing Kits

What Is Included

Each kit includes pre-measured, high-quality microbial compost packaged in a mesh brew bag alongside specialized microbial foods (kelp meal, fish hydrolysate, and mineral catalysts) engineered to maximize fungal and bacterial diversity during brewing.

Equipment Compatibility

• 5-Gallon Mini-Microbulator Compost Tea Brewer
• 50-Gallon Microbulator Commercial Compost Tea Brewer

Step-by-Step Brewing Instructions

1. Fill Container: Fill a 5-gallon bucket or 50-gallon tank with rainwater or de-chlorinated tap water. Connect a high-output air pump to maintain high dissolved oxygen levels throughout the brew cycle.
2. Add Kit Components: Place the mesh compost bag directly into the water and pour in the loose bag of microbial food.
3. Brewing Duration: Run your aeration system continuously for 18 to 36 hours.
4. Application Window: For maximum viability, apply your finished compost tea within 4 hours after turning off aeration.

Need more than 5 gallons? You can brew a concentrated batch in a 5-gallon bucket and dilute it with de-chlorinated water, or step up to our 50-gallon commercial equipment.

Application Methods & Frequency

Aerated Compost Tea can be applied as a foliar spray across the canopy or as a soil drench around the root zone:

• Application Tools: Use a standard watering can, gravity-fed hose, or a low-pressure sump pump. Microscope evaluations confirm that single-pass sump pumps do not harm beneficial microbes.
• Foliar Spray Technique: Spray with large droplet size and low pressure (a gentle "rainbow" pattern) to protect living organisms.
• Application Frequency: For new gardens or farms, apply 5 times per season (approx. 1 pint per plant as a soil drench). Established living soil systems can apply anywhere from weekly to 3 times per year based on crop requirements.

Storage & Moisture Maintenance

Store unopened kits in a cool, dark location (such as a basement). Avoid refrigerators or freezers, which dry out compost. Check unused compost periodically and add a few drops of de-chlorinated water if needed to keep it at optimal moisture.
