Bluelab Hydroponics Nutrient Solution pH and Temperature Measuring Pen.

pH is a critical fundamental to track for healthy growing plants. Potential hydrogen plays a pivotal role in nutrient solubility in water so nutrition can be absorbed by plants. A specific pH range needs to be maintained. If the growing solution becomes too acidic or too alkaline the plants will not be able to access the crucial nutrients needed for them to flourish.
Temperature needs to equally stay at an optimal range, too cold or too hot culture solutions affect growth rate and plant structure.
