Understanding modern growing media in agriculture

What role does growing media play in crop success? In this episode, we unpack the science behind specialised substrates such as coir, peat moss, perlite, and Hygromix, and their growing role in greenhouse, nursery, and intensive horticultural production. Featuring insights from Dean Oellerman of Greenhouse Technologies, the conversation explores root development, water management, germination, nutrient monitoring, and the realities of adopting soilless growing systems in Southern Africa.
