Company Profile 

Ultimate Products (Aust) Pty Ltd first started supplying the horticultural sector in June 1997 with a small range of 3 products, co-founder and current Managing Director Glen McDonald first started as a vegetable grower in 1983 and was always interested in new technology so Ultimate started to research new liquid suspensions to replace "the old" bulk gypsum and lime and by mid 1999 GYP-FLO and pH PLUS were released to the market. Today, both products are still leaders due to their suspension technologhy and effectiveness in their results.

Some 22 years on Ultimate has developed a product portfolio of 14 solutions that are supplied to Agriculture, Horticulture, Re-Veg sites and the Construction industries and exports to the U.K., Africa, Europe, NZ and Malaysia.
