Cannabis pH monitoring gives you a fast, clear read on the acidity or alkalinity of your water, nutrient mix, and growing medium, so plants can actually take up what you feed them. This handheld monitoring kit pairs a temperature-compensated probe with calibration buffers and a protective case, letting you check pH in seconds in soil, coco, or a hydroponic reservoir.
Key Features
- Digital probe with automatic temperature compensation for steady readings in warm reservoirs and cool tap water
- 0.00 to 14.00 pH range with 0.01 resolution and ±0.02 accuracy
- Two-point calibration using the included 4.00, 7.00, and 10.01 buffer powders
- Splash-proof, dust-resistant housing built for grow rooms, tents, and drip trays
- Backlit LCD that stays readable in dim gardens and low-light veg rooms
- Hold, auto-off, and low-battery alerts to protect readings and battery life
- Replaceable glass-bulb electrode and storage cap that extend probe life
- Hard travel case with slots for calibration cups, batteries, and a cleaning brush
Materials and Specifications
Built around a sealed glass-bulb sensor and a reinforced ABS body, the monitor is made for daily handling rather than a lab bench. The probe reads solution and slurry samples between 32°F and 122°F, stores up to 20 readings, and runs on two AAA batteries. Every kit includes calibration buffers, a rinse cup, storage solution, and a cleaning brush, so you have everything needed to start monitoring on day one.
What pH range should cannabis plants stay in?
Most growers target 5.5 to 6.5 in hydroponics and coco, and 6.0 to 7.0 in soil, because nutrient availability shifts quickly outside those windows. Staying inside the range keeps calcium, magnesium, and iron reachable for the roots.
How often should a pH monitor be calibrated?
Calibrate before first use, then roughly every two to four weeks, or sooner if readings drift after storage. Rinsing the probe in distilled water and keeping the storage cap damp helps hold accuracy between calibrations.
Can it measure runoff, soil slurries, and reservoir samples?
Yes. The sealed probe handles runoff, mixing cups, and soil slurries as long as you rinse it between samples, then wait for the number to settle before you log it.
Shipping and returns: orders leave the warehouse within one business day and arrive with tracking. If the monitor does not fit your routine, return it unused in its case within 30 days for a refund, and defective probes are covered by a one-year replacement policy.
