Plant growth chambers cannot duplicate all of the intricacies of continually changing environments, but properly designed chambers can produce daily and hourly changes in light and temperature with reasonable precision. Gradient, the most objectionable type of temperature variation, can be minimized by increasing air circulation and removing lamp heat as quickly as possible. Bulb age and temperature influence light intensity.
