“Purpl has transformed our grow. We just love it!” — CEO

The Challenge

GreenLeaf Cultivation was struggling with inconsistent product quality and long turnaround times for lab testing. They were sending multiple samples to third-party labs weekly, resulting in delays of 3-5 days per batch and costs exceeding $15,000 per month.

Without real-time data, the team couldn’t make quick decisions during critical growing and curing phases. This led to lost batches, reduced potency, and decreased customer satisfaction. They needed a solution that provided immediate, accurate results on-site.

The Solution

GreenLeaf implemented the Purpl PRO across their facility, training staff to test at multiple points in the cultivation and curing process. The device’s near-infrared spectroscopy technology provided lab-accurate results in under 10 seconds, allowing for real-time decision making.

The team integrated Purpl PRO testing into their standard operating procedures, checking moisture content during drying, validating potency before packaging, and educating buyers at point of purchase. This shift from reactive to proactive quality control transformed their entire workflow.
