KIS Organics Aerated Compost Tea Brewing Kits

KIS Organics Compost Tea Brewing Kits provide an easy, reliable, and microscope-tested way to produce high-potency Aerated Compost Tea (ACT). Formulated as a 100% natural, organic alternative to chemical pesticides and synthetic fertilizers, our compost tea kits boost plant resistance against environmental stress and pathogens. Regular applications improve nutrient cycling, expand root mass, enhance soil water retention, and help decompose soil toxins while improving crop flavor and yield quality.

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.

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.
