Get the fundamentals of runoff right, every time

Healthy plant growth starts with the right pH. In hydroponic and irrigated systems, plants can only access nutrients when the root zone stays within the right pH range.

Measuring runoff helps you understand what is happening around the roots. It shows whether your nutrient solution is staying available to the plant, or whether the root zone is drifting too acidic or too alkaline for efficient nutrient uptake.

By checking pH and Temperature in your runoff, you can spot changes early, make informed adjustments, and keep your crop in the optimal range for healthy plant growth.
