ABOUT US What is Protected Cropping Australia? Since 1990 we have been holding biennial conferences to provide both intending and commercial growers an opportunity to learn and network with industry leaders, and visit hydroponic and greenhouse farms. The lectures are published in books available for sale online. Originally called Australian Hydroponic Association Inc (AHA), then the Australian Hydroponic & Greenhouse Association Inc (AHGA) and now Protected Cropping Australia Ltd (PCA). This restructure was in honour of professionally representing the entire ‘controlled environment horticulture’ (CEH) industry with the four distinct membership sectors and positions on the Board.
