Don’t Assume Every Pot is the Same.

Uniformity is a myth in real-world growing environments.

Greenhouse Hot Spots & Dry Zones

Fixed sensors miss these variations. Soil Mini finds them.

The Reality

Fixed sensors monitor the average. But drippers clog, edges dry out, and different varieties drink at different speeds.

The Risk

Guesswork leads to salt blockage and uneven root development.

The solution?

A portable soil sensor that lets you check any zone in the greenhouse, any time.

Agility in Your Pocket

The flexibility to diagnose any zone, any substrate, any time.

EC Stability Comparison

Before Soil Mini

Erratic

Before Soil Mini – guesswork-based substrate monitoring in greenhouse

After Spot Checks

Stable

After Soil Mini – data-driven spot checks for precise substrate EC and moisture readings

Result:

More predictable growth cycles and reduced crop stress through proactive monitoring.

Minimize Risk

Prevent salt buildup and root rot by catching drainage issues early. Regular spot checks help you identify problem zones before they impact your entire crop.

Optimize Irrigation

Fine-tune your shot times based on actual root zone feedback, not just timer settings. Make data-driven decisions that save water and improve plant health.

Real ROI

In a 2023 trial at Proefcentrum Hoogstraten, sensor-driven irrigation with Soil Mini cut total water use by 19.5% and drain water by 38% — with zero yield loss. Growers using regular spot-checks also report up to 20% improvement in crop uniformity.
