Leading OEMs manufacture specific UV systems to continually disinfect the water being used in various soil-based and soil-less plant cultivation techniques, such as hydroponic systems. UV disinfection does not affect the pH or chemistry of the water and neutralises many organisms problematic to commercial horticulturalists such as fungi, viruses (including the tomato mosaic and tomato bronze viruses), moulds and mildew.
UV disinfection is increasingly popular for treating water used in horticultural applications, as it introduces no chemicals or unwanted disinfection by-products, which can stress plants and reduce crop quality. UV leaves no residue on the crops and helps employers provide a healthy environment for greenhouse workers. It also helps reduce the risk of pathogens developing resistance to commonly-used chemical disinfection methods – to date no organism has developed a resistance to disinfection by UV light.
