Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range.

From a water chemistry perspective, pH (potential Hydrogen) plays a pivotal role in making the nutrients in your solution soluble so that they can be accessed by your plants. That’s why if your growing solution becomes too acidic or too alkaline, the plants won’t be able to get access to the nutrients they need to grow. The temperature of your growing solution is equally important as having a solution that’s too hot or too cold can affect growth rate and structure.

To help your plants thrive, get the fundamentals right by measuring pH and temperature to ensure that these are always in the optimal range.


A compact and robust handheld solution
Everyday accuracy of the fundamentals

This user-friendly and hardy handheld pen will take measurements in increments of 0.1 pH and is fully temperature compensated, so you can expect accurate readings every time.

Our products are designed and built for grower environments - not the lab - so you can relax knowing that your pen can withstand the knocks, drops and deep-water plunges that come with everyday growing. In fact, the fully waterproof Bluelab pH Pen is designed to float when it lands up in your reservoir.

The Bluelab pH Pen was designed and assembled in New Zealand from local and imported components. Tried and trusted by growers all over the world, this essential tool is one of our top-selling products.

Conductivity and pH are connected. When preparing a new nutrient solution, you'll need to add the appropriate amount of nutrients according to the plants' needs. Once you’ve checked the conductivity (EC or PPM), which confirms whether the nutrient levels are correct, you'll then need to regularly adjust the pH to ensure those nutrients are available to the plant.

After all, nutrients are expensive so it’s important that you always optimise them.

With Bluelab’s Conductivity Pen, you can take measurements of your nutrient solution to ensure that your plants truly flourish.

Unlock your plant health fundamentals

Temperature is a key plant health fundamental, as it plays a pivotal role in your plants’ growth rate as well as their structure. Temperature also affects important plant processes, such as flowering and pollination.

That’s why you need to regularly measure the temperature within your plants’ growing environment. If it’s too warm, this could lead to oxygen deficiency and root infection. If it’s too cold, this could shock the roots, which may hinder plant growth.

Get the fundamentals of growing right by regularly measuring temperature to ensure that this is always within the correct range.

Accurate temperature measurements

The Bluelab Temperature Probe has been specially designed for use with the Bluelab pH Controller, Bluelab pH Controller Connect and Bluelab Pro Controller Connect. This reliable probe accurately measures the temperature of your nutrient solution.

Bluelab conductivity and pH measurements also use the temperature probe to automatically compensate readings for temperature, ensuring accurate measurements at all times.
