Compost Tea System 25 gallon with fine bubble diffusion for a superior compost tea biostimulant. Limited availability for 2026 season, taking preorders now for 2027, please call (360) 656-6680. Description From Growing Solutions, the System25 is the ideal size for one to five acre operations including specialty plant nurseries and farms, large home gardens and landscapes, retail garden centers, and research facilities. Affordable and easy to use, the System25 features the same patented design and industrial components as the larger Systems to create a compost tea biostimulant. Fine Bubble Diffusion Aeration Aeration disc with 4,000 1mm perforations for consistent bubble size and velocity. Provides thorough mixing inside the tank, eliminating the need for external agitation. Ensures maximum oxygen transfer efficiency, creating an optimum environment for reproduction of beneficial aerobic microorganisms. Each disc’s perforations self seal when the Compost Tea System is off, preventing back flow of Compost Tea into the air manifold. Aeration technology that has been in use for more than 40 years in many applications throughout the world. The System25 uses one Fine Bubble Diffusion aeration disc in the base of the tank. Strategic placement of the disc directly underneath the compost filter basket ensures thorough mixing and oxygen availability at the immediate area of extraction. Energy Efficient Growing Solutions uses the Alita linear magnetic blower for its energy efficiency, field longevity and ultra quiet operation. Operating on just 65 watts, this blower has a five-year continuous rating and regularly performs in the field for more than eight years. Custom Basket Tray The System25’s custom engineered compost filter basket tray houses one compost filter basket placed in a fixed location directly over the Fine Bubble Diffusion aeration disc in the bottom of the tank ensuring a high volume of air is surrounding the filtration area. This ABS tray is manufactured by an industrial vacuum-forming process to aerospace standards for precision, durability and longevity, and is completely recyclable. The System25 uses one Fine Bubble Diffusion aeration disc in the base of the tank. Strategic placement of the disc directly underneath the compost filter basket ensures thorough mixing and oxygen availability at the immediate area of extraction. Compost Filter Basket Airstone The System25 incorporates a sintered ceramic airstone placed in the compost filter basket. These industrial crafted airstones release a consistent pattern of air bubbles under low pressure in the center of the compost filter baskets, creating a buoyancy-effect that prevents compost compaction during the 24 hour brewing process. This additional air flow allows for a greater extraction of microbiology, nutrients and organic compounds. The airstones also provide oxygen inside the compost filter basket, ensuring that proper oxygen levels are maintained. Stainless Steel Filter Basket The System25’s industrial stainless steel and ABS compost filter basket is manufactured under rigorous quality standards. Incorporating precision stainless steel water jet and CNC laser cutting technology, this filter basket is extremely durable, designed for extended field-longevity and is the top of its class in compost extraction efficiency.
