Design and Deployment of a Regulation‐Compliant Infrared Heating System for UK Field Trials

Plant-Environment Interactions, Volume 7, Issue 5, October 2026.
ABSTRACT Free‐air warming systems are essential for simulating climate change in field conditions, yet most are not designed to meet UK or EU health and safety standards. We present the design and field deployment of a hexagonal temperature‐free air controlled enhancement (T‐FACE) system that meets UK and EU health and safety requirements for outdoor ...
