This document discusses hydroponics, which is the process of growing plants without soil by instead providing nutrients through a water solution. Some key points covered are that any plant can be grown through hydroponics, the basic requirements for home hydroponics like lighting, temperature and humidity levels, and that commercial hydroponic operations must grow thousands of plants to be profitable. The document also outlines the major and minor nutrient elements needed in hydroponic solutions to support plant growth.

2. Hydroponics
The growing of plants in a
solution of nutrients
necessary for plant
growth, rather than directly
in soil.

4. General Facts:
any plant can be grown in
a hydroponics system
almost any system will
produce acceptable
growth

5. General Facts:
Very few commercial
producers
Most facilities are
experimental, studying
plant nutrition

6. Different Names:
nutriculture
solution culture
slop culture
gravel culture

7. Requirements for
home hydroponics
best possible light
humidity 50% or more
day temp 75 degrees
night temp 65 degrees

8. Requirements for
home hydroponics
no need for special
drainage system
small scale, outstanding
plants such as tomatoes,
radishes, lettuce,
carnations, roses,

9. Commercial use
very familiar with plants
observation can
determine temps and
nutrient deficiency

10. Commercial use
to earn a reasonable
living you must grow
thousands of plants

11. Growers must know
about plants
most plants are very
adaptive
plants can take a lot of
abuse

12. Growers must know
about plants
plants require a minimum
amount of water, food,
vitamins, sleep and proper
temps.

13. Growers must know
about plants
each species has its own
requirements for maximum
growth

14. Major Elements in a
basic solution
Ca - Calcium
K - Potassium
N - Nitrogen
P - Phosphorous
Mg - Magnesium

15. Minor Elements
Mn - Manganese
S - Sulfur
Cu - Copper
B - boron

16. Minor Elements
Fe - Iron
Zn - Zinc
Mo - Molybdenum
