Innovators in horticulture

GT’s roots

Founded in the 80’s, where all the best things come from, Growth Technology’s roots started with 12,000 tomatoes

Growth Technology (known in the industry as GT), was the contract grower of tomatoes to Qantas, Australia’s national airline.

Unhappy with the fertilisers available at the time, GT set about creating their own hydroponic nutrients to meet their high standards.

Word spread and other growers wanted what they were having. GT’s unique range of crop-specific nutrients grew.

The world’s first

Along the way, GT’s innovative approach led to the creation of the world’s first propagation gel, Clonex.

Back to the future and the continued focus on science and innovation have made GT the market leader ‘behind the scenes’ meeting the needs of commercial growers across the world.

Such as GT Orchid Focus, originally developed for the Kew Royal Botanic Gardens in London.

GT today

Lucky for indoor plant hobbyists and home gardeners, GT made their professional range of crop-specific nutrients accessible to everyone with the GT Focus range of fertilisers and plant supplements.
