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.

All Growing Solutions Compost Tea Systems use a Fine Bubble Diffusion dynamic aeration process. Each Fine Bubble Diffusion aeration disc has 4,000 engineered perforations (1mm in size) that provide consistent air bubble size and velocity. The compost tea solution is thoroughly mixed by the Fine Bubble Diffusion aeration process inside the tank, eliminating the need for external agitation. This dynamic aeration process 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.

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.

Fine Bubble Technology aeration discs are found in all of our Compost Tea Systems. This aeration technology had been in use for more than 40 years in many applications throughout the world. The intelligent design of these discs help to realize highly efficient transfer of oxygen in the Compost Tea solution. The aeration discs are engineered with 4,000 1mm perforations with a one-way release air valve, a self-sealing design that prevents back-flow of any liquid when the disc is not inflated. The discs provide a high volume of aeration that creates a thorough homogeneity throughout the tank, eliminating the need for external mechanical mixing of the Compost Tea solution.

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.

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.

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.
