Energy Use Equipment Description
1 Low energy usage: Use low wattage LED and CFL lighting, low light fixture density (greater than 60 sq. ft. per light).  No supplemental cooling or heating to grow space.  No mechanical ventilation and air circulation.  No dehumidification, pumping, CO2 production, or additional energy usages.
2 Medium-Low energy usage: High wattage HID fixtures at low light fixture density (greater than 60 sq. ft. per light).  Very minimal or no supplemental cooling or heating to grow space.  Minimal mechanical ventilation and air circulation (ventilation only used minimally and not continuously to control temperature). No dehumidification, pumping, CO2 production, or additional energy usages.
3 Medium-high energy usage: High wattage HID fixtures with medium light density (40 - 60 sq. ft. per light).   Significant supplemental cooling and/or heating to grow space.  High-volume ventilation and air circulation that is frequently on.  Minimal dehumidification, pumping, CO2 production, or additional energy usages.
4 High energy usage:  High wattage HID fixtures, unvented, high light density (less than 40 sq. ft. per light).  Significant supplemental cooling and/or heating to grow space.  High volume ventilation and air circulation (high level of air changes) that operates majority of the time.  Multiple other energy using equipment, including dehumidification, pumping and water temperature control, CO2 production, etc.
Note:  Calculations assume typical 12-18 hour per day light operation for vegetative and flowering phases and a continous grow cycle.
