Living in south of Brisbane, Australia, Murray started doing Aquaponics 10 years ago and up till now he continues to create aquaponics systems for people and give trainings in various places. Check out this episode to learn more about media beds, rafts, hybrid systems, and the challenges in building aquaponics in 3rd world countries.
He talks more about biofertilizers such as compost teas and vermiculture, chelated iron, seaweed extracts and giant kelp powder, growing tomatoes, handling nutrient deficiencies, calcium carbonate, dealing with pH levels, and potash. He also expounds on various systems like the INDY 23 system, decoupled systems, and CHOP 2 system. We further delve into the topics of self-sustainability vs. community sustainability, interdependence vs. independence, protective cropping, growing bananas, Jerusalem artichokes, grains, and fruit trees.
Lastly, Murray touches a discussion on aquaponics as a business, creating multiple income streams, and a few good reasons many commercial aquaponics systems fail plus the main reason small businesses fail and some ways to get funding. Watch out for Murray's webinars soon!
