Q&A

Universol Hard Water is a line of water-soluble fertilizers specifically designed for use in hard irrigation water with high bicarbonate levels. Universol Hard Water acidifies the irrigation water and neutralizes the bicarbonates. It contains NPK and trace elements, and uses the Bright Solution System to ensure efficient nutrient uptake and clean irrigation systems.

 

To use Universol Hard Water fertilizers, dissolve the recommended amount in water and apply it to your plants. The specific application rate and frequency depend on the particular product and the needs of your plants.

Using Universol Hard Water fertilizers improves nutrient absorption due to neutralizing bicarbonates in hard water and stabilizing pH levels. The products promote healthy plant growth, enhance color and vigor, and help maintain the cleanliness of irrigation systems.

Yes, Universol Hard Water fertilizers are formulated for a wide range of plants, including pot plants, bedding plants, container nursery stock, and hydroponic crops.

It’s recommended to trial the product on a small scale before making any significant changes to your application rate or method. Ensure proper mixing and dissolution to avoid any issues with nutrient delivery. Furthermore, use Universol Hard Water in clean irrigation systems only, as the product’s anti-clogging effect can release deposits in the pipes, which can cause blockages in the system.
