Hydroponics

2. pumps a nutrient solution into aggregate beds from a reservoir most often located below the aggregate bed
3. cultivation of plants without the use of soil, but rather the nutrients produced by fish
6. hydroponic system with continuous flow of nutrient solutions over the plant roots, are the most common hydroponic system utilized by commercial producers
7. continuous flow system which use PVC pipes to hold plants and provide continuous flow of nutrient solutions
9. aggregate system which utilizes gravity to provide nutrient solutions to plant
10. needed by plants in small quantities; includes boron, copper and iron
12. process of circulating air throughout a substance
13. needed by plants in large quantities; includes nitrogen, potassium and sulfur

1. utilizes aggregate as a support medium for plants; utilizes flooding techniques which reduce water usage and drain afterwards, allowing the roots to aerate
3. material used for the support and stability of hydroponic plants; includes sand, gravel, peat moss and sawdust
4. hydroponic system with containers holding growing roots and watered using misters
5. continuous flow system which use flexible plastic tubing supported by wooden trays to hold plants and provide a continuous flow of nutrient solutions
8. production of plants without a soil medium; utilizes only water, sunlight and
