The Grower s Secret Story began in 1995 on a mushroom farm on Maui with a phone call that started a collaboration between two long time friends lab partners and plant pathologists Bryan Hiromoto and Wesley Chun both have degrees in plant pathology from U of Hawaii. Together they identified several species of edible mushrooms that produced nematicidal compounds. One mushroom was found to produce a compound that significantly stimulates plant growth. In 1998 Advanced Biological Research LLC (ABR better known as Albert Pleus Bryan Hiromoto Randy Harve) was formed and the process to produce large quantities of this compound in a liquid fermentation culture was developed. Field validation was conducted in Hawaii and by third party researchers with the support of a federal grant. By 2003 large bioreactor incubation was established and the growth enhancer was sold commercially as Liquid Compost Factor and in retail stores such as Ace Hardware KMart and Long's Drugs as PGE. In 2010 Chaz Berman agreed to commercialize the material and ABR became Grower s Secret Inc. The plant growth enhancer was rebranded as Grower s Secret Professional (GSP) marketing efforts were expanded and the company explored expanding the product line. After enhancing fish emulsion with GSP the company has added several organic fertilizers and supplements to its product line. In 2014 we added an organic high nitrogen fertilizer derived from soy beans called Grower s Secret Nitrogen 14 0 0 to our family. By 2015 GSI added Earth Emulsion 2 3 3. Today we offer 4 products all designed to do good for farmers and the earth. And we are always looking to follow in our founder's footsteps to conceive design and produce Innovative Organic Solutions so farmers have more choices to grow sustainably with little risk.
