| Question | Answer |
| a form of sub-irrigation in which potted plants are set on a moist synthetic mat and water moves upward through the drain holes into the growing medium by wick action | Capillary mat system |
| automated system utilizing fabrics to insulate the greenhouse at night | Energy curtains |
| a system in which large exhaust fans draw air through a moistened cellulose pad mounted on the opposite end of the structure | Fan-and-pad cooling system |
| fans bring in small amounts of cool outside air and mix it with the warm air | Fan-tube ventilation |
| equipment used for the irrigation of plants with exact proportions of fertilizers obtained from a concentrate of water-fertilizer and water | Fertilizer injector system |
| cooler and more efficient that incandescent lights; have a wide range of wavelengths and long life | Fluorescent lighting |
| fog is generated inside; as the minute fog droplets evaporate, heat is absorbed | Fog-evaporative cooling system |
| localized heater units that force hot air directly into a duct system | Forced air-heaters |
| efficient and effective supplemental lighting system | High Intensity Discharge (HID) lightingsystem |
| manual watering of plants | Hose watering |
| water is heated in a boiler and pumped through pipes | Hot water heat |
| inefficient and gives off primarily infra-red wavelengths; often used for photoperiod control | Incandescent lighting |
| individual heater units that produce infrared radiation | Infrared radiant heaters |
| watering method; tiny droplets delivered periodically keep plants moist | Intermittent mist system |
| air is exchanged through open ridge and side vents and controlled by thermostats | Natural ventilation |
| water is applied over the canopy of the plants with spray nozzles | Overhead watering |
| watering around the outside of a flower bed | Perimeter irrigation |
| automated system utilizing fabrics to block light from reaching crops | Shade curtains |
| automated system utilizing fabrics to insulate the greenhouse at night | 19. Short-day curtains |
| water is applied to the growing medium by slowly saturating the medium | Soaker hose system |
| water heated to a boil and steam travels through pipes in the greenhouse | Steam heat |
| water is carried to each pot by a microtube; foliage is not wet in this process | Tube irrigation |
