Endless Biotech is redefining cannabis cultivation through innovation, precision, and a commitment to clean genetics. As a leader in tissue culture and ready-to-flower plants, they needed a substrate that could match their pursuit of consistency and efficiency at scale. The unpredictability of coco coir led to challenges with irrigation control, pest management, and labor efficiency—hindering scalable, high-performance production.

By transitioning to Grodan stone wool, Endless Biotech gained the precision they needed to fine-tune their crop steering, improve plant uniformity, and maximize genetic potential. The results were immediate: increased yields, enhanced terpene expression, and a more streamlined workflow that allowed their team to focus on innovation instead of substrate inconsistencies.

With yields reaching up to 147g per square foot and terpene levels climbing to 6%, Endless Biotech has unlocked new efficiencies in high-performance cultivation.
