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. By...

"Is your coco already buffered? Is it already charged? And what nutrients should you feed first?” We hear these questions all the time. The good news? Our coco is prepped and ready to go—setting your plants up for strong, healthy growth from day one. Starting with the right foundation makes all the difference, giving your plants the best chance to thrive. First, what do...

  Coco coir differs from other substrates in many ways, but one big difference is the anion capacity. What does this mean for nitrogen levels in your nutrient solution? The overall level of nitrogen in your nutrient solution should be based on the plant's need for nitrogen, which is dictated by the amount of photon energy received by the leaves. Higher PPFD levels mean...
