Across
- 2. Ventilation most basic way of cooling a greenhouse environment; by opening the ridge and side vents, warm air is allowed to escape and cool air is drawn inside allowing the cool air to keep the temperature down
- 3. one consideration of greenhouse site selection; an area’s climatic factors include light intensity, seasonal temperatures, prevailing fog or cloud conditions and wind patterns
- 7. Plants plants which flower according to certain day lengths
- 8. Quality one of several considerations of site selection because all greenhouse plants are affected by contaminants such as sulfur dioxide, ozone and carbon monoxide, air quality must be considered
- 11. metal commonly used as a greenhouse framing material for structural components such as roof bars, purlins and posts
- 14. cloth-like material hung over growing benches to decrease the light intensity reaching plants in a greenhouse or out-of-doors; cheesecloth is sometimes used as an inexpensive but short-lived alternative to saran
- 15. System greenhouse equipment designed to provide water to plants
- 16. Materials materials such as wood and aluminum used for the structural components of a greenhouse
- 17. interior components of a greenhouse structure commonly used to support propagation flats and potted greenhouse plants
- 19. Temperature best growing temperature for a greenhouse crop during a specific stage of development; crops may have several stages of development and hence several optimum temperatures may be needed
- 20. separate growing areas with potentially different environments structural component
Down
- 1. environmental factor manipulated in propagation areas of greenhouse production; decreases water loss from plant leaves while roots are forming
- 4. Greenhouse greenhouse shape with a peaked roof; also know as a “peaked-style” greenhouse
- 5. Greenhouse gutter connected greenhouse with shared inner walls; such construction creates separate growing areas with potentially different environments
- 6. Intensity magnitude of radiant energy entering the greenhouse; can be measured in foot candles using an electronic light meter
- 9. structural component of a greenhouse which connects the sidewall and the roof of the structure
- 10. Panels (Fiberglass) one type of rigid plastic used for greenhouse glazing; provides uniform light intensity and average heat retention, but discolors over time and may be flammable
- 12. Compound white liquid material, often diluted latex paint, which is sprayed on to the outside walls of a greenhouse to decrease light intensity inside the greenhouse
- 13. Irrigation irrigation system which uses nozzles placed around the edges of growing beds to provide water to bed-grown plants
- 16. Plastics includes several types of greenhouse glazing materials; most common being polyethylene
- 18. Greenhouse greenhouse whose structural components include more than one type of framing material; consists of steel trusses and wooden roof bars
