The Best pH Level For Your Hydroponic Vegetable Garden

NoSoilSolutions

It’s important to measure the pH of your hydroponic garden on a regular basis. Plants are not able to take in nutrients when your nutrient water falls out of a certain pH level. Most plants prefer a pH level that is slightly acidic, around 5.0 to 6.5. To get the most out of your plants its best to tailor the pH to the plant your growing.
