Crop steering in coco coir is often misapplied due to container volume based irrigation assumptions that do not reflect how water actually behaves in flexible grow bags. This article presents a field capacity based crop steering framework developed specifically for HortGrow coco grow bags, defining shot size, dry back targets, and irrigation windows in terms of plant available water rather than nominal liters. By...

The physical structure of a substrate determines how water, air, and nutrients move through the root zone. In controlled environment horticulture, this comes down to texture. The balance of particle sizes and fibers that make up the medium dictates porosity, water holding capacity, oxygen availability, and how evenly irrigation is distributed. Coco coir is naturally versatile, but its performance depends on how it is...
