Description
In this Growing Exposed IG Live, Justin sits down with Pim van Seventer, owner of Aqua Master Tools, for a deep dive into one of the most overlooked fundamentals of cultivation: measurement. Drawing on more than two decades of experience in the industry, Pim shares how early frustrations with unreliable meters inspired the creation of Aqua Master Tools and a new generation of precise, affordable testing equipment for growers.
The conversation explores why monitoring pH and EC is critical for plant health, how improper pH can lock out nutrients even when feeding schedules are correct, and why tools like runoff testing can reveal what’s really happening in the root zone. Pim also explains how pH probes actually work, why they have a limited lifespan, and how proper storage, cleaning, and calibration can dramatically extend their accuracy and performance.
Throughout the discussion, the two also touch on nutrient management, media choices like rockwool and coco, and how small adjustments in measurement and technique can make the difference between struggling plants and a thriving crop. The episode offers practical insights for growers at every level who want to better understand the science behind healthy cultivation.
