What is the Bluelab Leap™ pH Probe used for?
The Bluelab Leap™ pH Probe is a spear-tip pH sensor designed for direct root-zone testing in soil, coco, rockwool, potting mixes, and also works in hydroponic nutrient solutions. It gives more accurate insight into what’s happening around plant roots compared to runoff or feed readings.
What makes the Bluelab Leap™ pH Probe different from standard pH probes?
Its reinforced spear tip is made for direct media insertion without damaging the sensor. The double-junction design helps prevent contamination, making it more durable in nutrient-rich or organic environments—ideal for both hobby and professional growers.
How do I take accurate pH readings with the Bluelab Leap™ pH Probe?
Insert the probe into moist root-zone media (not dry), avoiding pot edges or repeat spots. Wait for the reading to stabilise and test 2–3 different areas per container to get a true picture of substrate pH.
Can I use the Bluelab Leap™ pH Probe with my existing meter?
Yes—it’s compatible with Bluelab Combo Meters, Multimedia pH Meters, and other devices using a standard BNC connector. It includes a 2-meter cable, but extending it may reduce accuracy unless high-quality BNC extensions are used.
Does the Bluelab Leap™ pH Probe need calibration?
Yes—use 2-point calibration with fresh pH 7.0 and pH 4.0 buffer solutions. Monthly calibration is recommended, or more often if you measure daily, use organics, or see signs of drift.
How do I know when to recalibrate or clean the probe?
If readings are slow, unstable, or don’t match buffer checks, recalibrate. Clean the probe using proper electrode cleaner, rinse well, and recalibrate to restore accuracy.
How should I store the Bluelab Leap™ pH Probe when not in use?
Always store the probe tip wet in KCl storage solution using the included storage cap. Never let it dry out or store in RO/distilled water, which can damage the sensor and shorten lifespan.
What should I do if the probe dries out?
Soak the tip in proper pH storage solution for 24 hours to rehydrate. After soaking, recalibrate before taking new readings. Avoid dry storage to maintain probe performance.
Can the Bluelab Leap™ pH Probe be used in hydro, fabric pots, or seedling containers?
Yes—just make sure the media is moist. Be gentle in smaller pots to avoid damaging roots, and rinse the probe between readings to prevent contamination across plants or systems.
Will strong pH adjusters or extreme temperatures damage the probe?
Yes—avoid direct contact with undiluted pH Up/Down or raw concentrates. Also, very hot or cold media can affect reading speed and accuracy. Measure at stable temperatures for best results.
Why are pH readings different in the same pot?
pH can vary across the root zone due to uneven watering, salt buildup, or microbial activity. That's why testing multiple spots gives a more accurate overview than relying on a single reading.
Can the Bluelab Leap™ pH Probe help prevent nutrient lockout?
Yes. Monitoring substrate pH helps catch issues before they show on leaves. If your media pH is off—even if feed pH is correct—nutrient uptake can be blocked.
How long does the Bluelab Leap™ pH Probe typically last?
With proper care—regular cleaning, calibration, and correct storage—it can last significantly longer than standard probes. Signs it needs replacing include slow readings, calibration failure, or unstable results even after maintenance.
Can I repair a damaged Bluelab Leap™ pH Probe?
No. If the sensing glass is cracked or the probe fails to calibrate after cleaning and rehydration, replacement is the best option. Always handle the tip gently and store it properly.
What’s the best routine for maintaining the Bluelab Leap™ pH Probe?
Calibrate monthly, measure in moist media, test multiple spots, rinse between readings, clean when needed, and always store the tip wet in storage solution. Good habits = long life and accurate readings.
