3 WAYS T CLEAN : by Karen Lloyd DISINFECTING HYDROPONIC WATER 62 Maximum Yield A sure-fire way to quickly kill hydroponic plants is through pathogens in the water supply. By keeping water clean, growers can practice environmental responsibility while enjoying quality yields. P racticed around the world, hydroponics is especially advantageous where climates restrict plant growth, where low-quality soil won’t support large-scale production, and in countries where once fertile soil has been over-farmed. The availability of fresh water is also an important variable as clean, recycled water is a valuable resource. Hydroponics reduces consumption of fresh water from our already endangered water supply — a recent report states agriculture uses 70 per cent of available fresh water, while industry uses about 25 per cent and residential uses five per cent worldwide. The benefits of recycled hydroponic water for small and large operations include cost savings and higher crop yields. To reduce the risk of recycled water spreading bacteria, viruses,
