Bluelab Multimedia pH Probe allows you to measure pH directly in the root zone in soil, coco, rockwool, and potting mixes. Tempered glass tip, BNC connector, and 2 m cable ensure accuracy and convenience in indoor cultivation.

The Bluelab Multimedia PH Probe (model PROBPHLEAP) is a professional replacement designed for direct measurements in the growing medium, where the roots really matter.
The sensor works with a tempered glass tip optimized for fast response, while the double junction increases stability and reduces ionic contamination, which is key when concentrated fertilizers or active substrates are present. The assembly is done via a standard BNC connector, making it compatible with Bluelab equipment that accepts this format.
The set incorporates a waterproof cable seal to withstand common splashes on mixing tables and tanks. Reference dimensions: 17.8 × 3.8 × 3.8 cm; diameter Ø12 mm; cable length 2 m which makes it easy to reach distant pots or deep trays.
The “multimedia” approach allows direct sampling in soil, coco fiber and rock wool, as well as checking pH in nutrient solutions and drainages to compare tank vs. root zone.
This in situ reading reduces trial and error, prevents lockouts due to out-of-range pH, and speeds up corrections during growth, transition, and flowering in cannabis cultivation.
As part of the cultivation meters and indoor accessories ecosystem, it stands out for reliability, ease of use, and simple maintenance with cleaning and storage solutions.

In indoor cultivation, the substrate pH determines the real availability of macro and microelements. The Bluelab Multimedia PH Probe allows you to check if the target value is maintained in the root zone regardless of the tank. This verification helps detect deviations due to substrate buffering, salt buildup, or irregular watering, allowing quick adjustments that stabilize yield in cannabis plants.
It is used to measure pH directly in the growing medium and in irrigation solutions, providing an accurate diagnosis of the environment where the roots work. With this data, it is possible to adjust with pH regulators, plan flushes, correct recipes, and define more efficient irrigation windows. Direct reading in substrate complements tank control and reduces surprises during flowering.
As a tool, it provides a tempered glass tip for fast response, double junction for stability, BNC connector for secure connection, and 2 m cable that reaches large pots or separate tables. The design makes it easy to work in soil, coco, and rock wool, so it fits in indoor cultivation installations where several substrates coexist. A key piece within cultivation meters aimed at consistent results.
1) Connection: attach the BNC connector to the compatible meter and check that the connection is firm and dry.
2) Preparation: rinse with clean water and, if applicable, condition with storage solution. Avoid touching the glass tip with your fingers.
3) Measurement in substrate: open a small guide hole and carefully insert the probe to the desired depth; wait for stabilization and record the value.
4) Measurement in solution: immerse the tip in the tank or drainage, stir gently and record the reading when the value is stable.
5) Calibration and care: calibrate the system according to the meter's routine (pH 7 and pH 4/10). Clean with specific cleaning solution; store the tip in suitable conditions to preserve the membrane and reference.
6) Good practices: sample several pots per area, work at comparable humidity, and record data by stage to correlate with yield.
