Understanding Hydroponics

1. Elements: Nutrients that plants require in only trace or small amounts
4. Medium: The "soil" used to grow the plant with may or may not contain actual soil. Usually Composed of a mixture of peat moss, perlite, and, or other materials to provide support and moisture retention
8. A portable platform
9. The movement of water from the plant roots out through the leaves
12. The simple sugars that result from photosynthesis
13. A mixture of water and nutrients used in hydroponics
17. A material added to soil to increase it's fertility
20. The series of processes a plant goes through to convert food into energy
21. Molecules or compounds that contain carbon. Ordinarily carbonates are not recognized as being organic
24. Light: A special fluorescent light that provides plants with the proper type and amount of light for growth
25. Having a pH of more than 7.0
28. The Greek word for water
29. The brightness of a light source

2. The green pigment found in plants leaves and stems
3. The amount of light falling on a surface one foot away from a candle
5. An index of the acidity or alkalinity of a substance
6. Growing plants without soil
7. Reservoir: A container that holds the nutrient solution in a hydroponic system
10. The process by which chlorophyll in plant leaves converts sun and nutrients into photosynthates
11. The amount of water vapor present in the atmosphere
14. Expose the plant roots to the circulation of air
15. Matter: Solid components of soils resulting from the partial
16. A fundamental substance that comprises matter
18. A floating,Mexican raft used for hydroponics on marshes
19. Te Greek word for work
22. Having a pH of less than 4.0
23. Spectrum:The colors within a light source
26. Irrigation: Point specific irrigation accomplished through the use of piping and tubing with emitters locates at strategic watering points
27. Elements: Nutrients that plants require in large amounts
