From an early pioneering start in the 80's, they evolved into Australia's biggest hydroponics retailer with 13 retail shops. The need to have a supply base to support the retail chain prompted the development of Holland Forge Wholesale Hydroponics Pty Ltd. The success of their venture into wholesaling inspired them to concentrate purely on that, thus selling off their retail interests. They are now the largest stand as a purely wholesale company with no affiliation to any retail outlets. We, at Hydro Experts, sell Holland Forge De-Fuse Hydroponics Nutrient Conditioner.
