GROW is a biofertilizer with a mix of microbial inputs developed over many years of research and although they are the company’s ‘trade secret’ here are some of the names of the beneficial bacteria, algae, fungi and other ingredients found in GROW:

Azotobacter vineladii; Bacillus cereus / thuringienis; Bacillus subtillis; Bradyrhizobium japonicum; Chaetomium globosum; Endo & Ecto Mycorrhiza; Fusarlam spp; Nematodes; Ochrobactrumanthropi; Protozoa – flagellates, amoebae, ciliates; Pseudomonas aeruginosa; Pseudomonas fluorescens; Pseudomonas pseudoalcaligenesl; Pseudomonas putida; Pseudomonas stutzeri; Rhizobium leguminosarum; Sphingomonas paucimobillis; Streptomyces albidoflavus; Streptomyces celluosae; Trichoderma lignorum;

This combination helps build soil micro-flora and thereby, soil health. The importance of healthy soil and complete, plant acceptable, nutrients has been well documented by many experts over the years. The benefits of GROW can be shown in independent trials run by Dr Rogers of Applied Horticultural Research, including increased yield, improved soil health, greater resistance to pest and climatic variation, and greater water efficiency. Researchers have also found that the use of highly refined biofertilizer such as GROW can reduce production costs by supplementing inorganic/chemical fertilizer use through promoting improved soil microbial populations, including free-living nitrogen fixing bacteria such as Azotobacter, improving nutrient uptake through better root development.
See a summary of Dr. Rogers results here.

Rhizobium Bacteria: vital symbiotic nitrogen-fixing bacteria, meaning the plant helps them with food and shelter and in return they provide the plant with much needed nitrogen.

Azotobacter Bacteria: protects the roots from pathogens present in the soil.

Mycorrhizal Fungi: the independent gut of the plant. Once connected to the plants root system it mines and delivers often out of reach minerals, water and other nutrients into the plants metabolic process.

Bacillus Bacteria: capable of inhibiting plant disease caused by protest pathogen.
