2. Hydroponics is a subset
of hydroculture
Hydrophonics is one methodology
of soil-less cultivation
It is a method of growing plants
using mineral solution, in water
without soil
The earliest published work on
growing terrestrial plants without
soil was the 1627 book Sylva
Sylvarum or 'A Natural History'
by Francis Bacon
3. To survive plants do
photosynthesis.
• It needs water, carbon-di-
oxide, sunlight, chlorophyll
For growth and development it
needs
•Nutrients and growth
regulators(hormones)
Soil is essential for absorption
of nutrients
4. Coco-peat or coco-coir
Containers (two in number)
Waste water:
vegetable peels and other domestic
wastes, ground egg shell, meat or fish
washed water are kept in a bin and
allowed to rot for few days.This will
give out water and that water is taken.
A needle to make pores
5. Two waste containers are taken ,one should fit
into the other
One is perforated using hot pin Other is left undisturbed
Coco-peat is added to it It is filled with nutient solution(Water
from rotten household waste like
vegetable peels, egg shell, fish and meat
washed water)
The containers are fit over another. And our setup is ready
The setup is left undisturbed for few days. Seeds of plant to be grown are
spread over the coco-pit. And after few days new plant germinate.

7. Problems faced for plant cultivation Solutions
Draught conditon Soil-less cultivation
Unpredictable weather and lack of
irrigation
Water stays in system and can be reused
Under nourished and over nourished
crops
Nutrient level can be controlled easily
Other Advantages
Rare medicinal plants can be grown
Highly economic
Easy to get rid of pests and easy to grow
Ensures proper waste mangement
8. An innovative approach
to reuse household organic
waste.
Cooking herbs and
medicinal herbs both can
be grown
Encourages reuse and
recycling
People living in crowded
streets without garden can
cultivate their own crop.
