Hydroponics Review

4. hydroponic system with containers holding growing roots and watered using
5. most often in the form of sand or gravel
7. material used for the support and stability of hydroponic plants; includes sand,gravel,peat moss and sawdust
8. aggregate system which utilizes gravity to provide nutrient solutions to plant roots
9. utilizes only nutrient infused water and system structures to produce plants
11. continuous flow system which use PVC pipes to hold plants and provide continuous flow of nutrient solutions
13. to hold plants and provide a continuous flow of nutrient solutions
14. continuous flow system which use flexible plastic tubing supported by wooden
15. hydroponic system with continuous flow of nutrient solutions over the plant roots; are the most common hydroponic system utilized by commercial
16. process of circulating air throughout a substance
17. aggregate system which utilizes gravity to provide nutrient solutions to plant roots; manual operation is needed to drain used nutrient solution
18. needed by plants in large quantities; includes nitrogen, potassium and sulfur

1. needed by plants in small quantities; includes boron, copper and iron
2. production of plants without a soil medium; utilizes only water, sunlight and nutrients
3. continuous flow system which uses mesh tubing with vertical inserts filled with peat moss to hold plants and provide a continuous flow of nutrient solutions
6. utilizes aggregate as a support medium for plants; utilizes flooding techniques which reduce water usage and drain afterwards, allowing the roots to aerate
10. plants with the feasibility to grow hydroponically
12. pumps a nutrient solution into aggregate beds from a reservoir most often located below the aggregate bed
