Formulated to foster a thriving community of beneficial microorganisms, this compost tea catalyst blends seaweed extract, mineral powder, and a selection of botanical ingredients—without the addition of simple sugars. By supplying a broad spectrum of nutrients and trace minerals, it encourages diverse microbial growth during aerated compost tea production, helping to improve soil structure, nutrient cycling, and plant vigor.

With its 4.5-lb size, this catalyst is ideal for frequent brewers, market gardeners, or small farms seeking consistent, high-quality compost tea for regular applications. One box treats up to 250 gallons, making it a cost-effective option for large garden beds, orchards, or landscape plantings. It works seamlessly with all types of compost tea brewers and is easy to integrate into your current practices—simply measure, mix, and brew to produce a biologically rich tea for soil drenches or foliar sprays.

Using compost tea enhanced with this catalyst supports robust root development, improved nutrient uptake, and greater resilience to environmental stresses. It promotes a balanced soil food web that reduces reliance on synthetic fertilizers and fosters long-term soil fertility.
