Coco Coir and Hydroponic Cultivation Glossary A Technical Reference for Hydroponic Production in Controlled Environment Agriculture Aeration The presence and movement of air within the substrate root zone. Aeration is governed by air filled porosity and pore structure and is essential for oxygen diffusion to roots. Inadequate aeration leads to reduced root respiration, impaired nutrient uptake, and increased susceptibility to root pathogens. Air Filled...

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.
