How These Tools Help Growers

Consistency, clarity, and control

Reliable pH/PPM/EC data turns guesswork into repeatable SOPs. You’ll mix nutrients faster, verify strengths before irrigating, and spot drift early—protecting roots from imbalance, improving uptake, and keeping canopies uniform. With proper calibration and probe care, readings stay accurate season after season.

Frequently Asked Questions

What is EC and PPM in hydroponics?

EC (electrical conductivity) measures a solution’s ability to conduct electricity, which correlates to dissolved salts (nutrients). PPM (parts per million) or TDS estimates total dissolved solids derived from EC using a conversion factor. Both indicate nutrient strength.

What is the optimal pH and EC for hydroponics?

Most crops thrive around pH 5.5–6.5 depending on species and stage. EC targets vary by crop and growth phase (e.g., lower in propagation, higher in aggressive veg/finish). Always follow crop-specific guidelines and monitor plant response.

What is a good PPM for hydroponics?

Good PPM depends on crop and stage: seedlings/starts are typically low, while established plants tolerate higher levels. Use manufacturer feed charts as a starting point, then fine-tune based on runoff readings and plant health.

Why is pH monitoring important in a hydroponic system and what is the ideal pH range for growing?

pH controls nutrient availability at the root zone. Out-of-range pH causes lockout or toxicity even when EC/PPM is correct. A common ideal range is 5.5–6.5 for most hydroponic crops.

How do you measure electrical conductivity in hydroponics?

Use an EC meter or combo meter. Rinse the probe, immerse it in the solution, let the reading stabilize, and compare to your target. Calibrate regularly with EC standards and keep probes clean and stored properly.
