How does water quality affect root rot in indoor hydroponics?
As a hydroponics hobbyist based in Dubai, I know that water quality is crucial for plant health. However, I've recently faced some challenges with root rot in my system, primarily with my lettuce and spinach. My water source is tap water, which I treat with a reverse osmosis filter, but I've been unsure if the quality is optimal for my plants. I've tested the EC and pH levels, but I wonder if there are other parameters I should be considering, like dissolved oxygen levels or contaminants. How do these factors influence root rot, especially in a soilless environment? What best practices can I implement to ensure my water quality is supporting healthy root systems? Any advice would be a great help!
