Collection: Bluelab pH and EC pens

Healthy hydroponically grown plants need a balanced diet of appropriate nutrientsΒ (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range. Therefore, monitoring the nutrient and pH level regularly is paramount to successful Hydroponic growing. These can both be achieved using a pH pen and an EC pen (nutrient reader pen).
