Nutrient solutions need to be set at a specific pH level for plants to access all the minerals needed for growth, too acidic or too alkaline, and problems are sure to follow. Temperature is another key factor that affects the growth rate and structure of a plant so a solution temperature of 18 - 22˚C or 65 - 72˚F is recommended.
