Testing the pH and EC levels in hydroponics is vital for maintaining a healthy and thriving garden. The pH level determines the acidity or alkalinity of the nutrient solution and is crucial for the proper uptake of nutrients by the plants. If the pH is too high or low, plants cannot absorb nutrients effectively, leading to stunted growth, yellowing leaves, and other deficiencies. The EC (electrical conductivity) measures the concentration of dissolved salts in the solution, which indicates the level of nutrients available to the plants. High EC levels can lead to nutrient burn, while low levels can lead to deficiencies. By regularly testing pH and EC levels, you can make adjustments to the nutrient solution and ensure optimal growing conditions for your plants. This practice promotes healthy growth, better yields, and fewer plant health issues, helping you achieve the garden of your dreams.
