In this episode of Hydroponics Daily, Dr. Russell Sharp, the creator of renowned fertilizers "Gold Leaf" and "Liquid Gold," addresses a common inquiry about why these products aren't available in garden centers. Dr. Sharp delves into the underlying reasons, including the focus on cheap, substandard ingredients commonly found in garden center fertilizers and the lack of essential nutrients like calcium and sulfur. He highlights the misconceptions surrounding seaweed extracts and the illusion of targeted fertilizers, such as those for tomatoes and orchids, often being merely diluted versions of a base product. Dr. Sharp also emphasizes the drawbacks of buying from garden centers, like poor after-sales support and products being stored in non-optimal conditions, leading to reduced potency. He argues for the value of purchasing from specialist hydroponic stores, where quality and tailored advice are prioritized. Listeners are encouraged to seek out fertilizers with transparent ingredient lists and avoid the trap of ready-to-use, diluted products marketed for their convenience but at a cost to effectiveness.   https://eutrema.co.uk/shop/fertiliser/liquid-gold-unique-complete-fertiliser/
