Reusing Growing Media

In this episode of Hydroponics Daily, Dr. Russell Sharp delves into the realm of reusing growing media. Discover the environmental and economic benefits of reusing substrates, the challenges posed by residual salts, and methods to lower electrical conductivity for healthy plant growth. Explore solutions for managing root-bound media and learn how worms and composting can transform old substrate into nutrient-rich soil. Highlighting the complexity of reusing synthetic media like rockwool, Dr. Sharp offers insights into sustainable practices and invites listeners to consider future innovations in growth media reuse.
