Bluelab offers high-quality solutions formulated for calibrating and/or testing pH probes. All plants need a balanced diet of nutrients (food) so that they can reach their full potential. The pH (potential Hydrogen) of your nutrient solution plays a pivotal role in making these elements available to your plants. That’s why you need to regularly measure pH; if your medium is too alkaline or too acidic, your plant won’t be able to access all the nutrients they need. Whether you’re looking for the best pH meter for hydroponics or need to test soil pH, we have a pH meter that will help you accurately measure your pH. Our products include handheld pH pens, automated pH controllers, and wall-mounted monitors. pH 7.0 calibration solutions - a must in every grower’s toolbox!

Available in Michigan only.
