Medical Saints: Record Yields After Transition from Coco to Stone Wool

Rooted in Science Icon (Green)

Medical Saints, one of Canada’s leading private cannabis producers, transitioned from coco-based substrates to Grodan stone wool to improve yield, efficiency, and plant quality. As their production scaled, they needed a solution that provided greater consistency, precision control, and sustainability while minimizing resource waste.

By optimizing irrigation, root zone management, and crop steering, they achieved a record 225g per plant, along with stronger root development and reduced labor costs. The switch to Grodan stone wool also allowed for better moisture distribution, enhanced oxygen availability, and real-time data insights—all critical for maximizing plant health and uniformity.

With THC levels reaching 27-31% and terpene concentrations as high as 4.2%, Medical Saints set a new benchmark for high-performance cultivation.
