Growth Chamber

Plant growth chambers are designed to produce environmental conditions (humidity and temperature) that maximize plant growth. They are sometimes called environmental chambers or terrestrial plant growth chambers.

Plant growth chambers are available with downward air flow and upward airflow. Downward airflow in plant growth chambers comes through air diffusers at the top of the chamber’s walls. Air-handling plenums provide a stable and uniform plant canopy temperature. Downward airflow plant growth chambers are ideal for growing plants in trays and pots. Upward airflow operated in conjunction with tapered air-handling plenums through the chamber floor. A constant combination of air volumes and velocities ensures a consistent environment. Plant growth chambers that use upward airflow are best for growing plants in pots or doing tissue culture work
