Buying Guide
What to consider when choosing compost tea brewing gear:
- Brewing volume: Do you brew in 5 gallons, 30–50 gallons, or somewhere in between? Choose kits designed for your typical batch size.
- Aeration versus filtration: If your priority is keeping dissolved oxygen high, prioritize aeration pumps and diffs. For easy ingredient handling, consider breathable brew bags with sturdy closures.
- Ease of use: Beginners benefit from complete kits with clear assembly steps. More experienced users may prefer modular components they can customize.
- Durability and materials: Look for food-safe plastics, stainless hardware, and nylon mesh that withstand repeated use and cleaning.
- Maintenance: Bags and pumps should be easy to clean and sanitize. Consider components that are dishwasher-safe or easy to rinse.
- Compatibility: Ensure your brew vessel and bag size align with the bag’s dimensions and the aeration system’s capacity.
