Testing Supplies & pH Control
Hydroponics involves providing plants with adequate water, oxygen, and nutrients in balanced quantities. Maintaining this balance is essential for optimum plant growth and yield. For this, you should monitor the levels of pH and total dissolved solids (TDS) of the nutrient solution or soil you use. What do these terms mean? The pH scale measures the acidic or alkaline content of a substance. TDS refers to the combination of inorganic salts and organic matter that are dissolved in water. By monitoring both the pH and TDS levels allows you to have more control over your crops.
