4. Introduction
# Soil is usually the most available growing medium for plants. It
provides anchorage, nutrients, air, water, etc. for successful plant
growth. However, soils do pose serious limitations for plant
growth too, at times and hydroponics was introduced for the
betterment of people
# Hydroponic cultivation is a method of growing plants without
soil, using a nutrient-rich water solution to deliver essential
minerals directly to the plant roots
# Hydroponics is a Greek word meaning “hydro” (water) and
“ponos” (labour) is the method of growing plants in liquid
medium (water), in which nutrients are added, but no soil is used .
# The word hydroponics was coined by Professor William
Gericke in the early 1930s describe the growing of plants with
their roots suspended in water containing mineral nutrients.

5. # This soilless system allows for precise control over nutrient levels,
pH, and environmental conditions, promoting faster growth and
increased yields.
# The key components of hydroponic systems include a nutrient
reservoir, a pump to circulate the nutrient solution, and various
growing mediums such as perlite, vermiculite, or coconut coir to
support plant roots.
# Hydroponic cultivation offers several benefits, including water
efficiency, reduced reliance on pesticides, and the ability to grow in
limited space.

6. Objectives
•Transforming kitchen waste into hygienic liquid nutrient solutions suitable for indoor
vegetable plants aims to curtail the volume of waste added to municipal disposal while
promoting a sustainable and beneficial recycling process.
•To cultivate mint, cucumber, and tomato in a hydroponic system with the use of
nutrient solutions obtained through kitchen waste by bore water and portable water
•Assessing the effectiveness of the hydroponic system by comparing its performance
when utilizing biofertilizer and chemical fertilizer as nutrient solutions.

7. METHODOLOGY
Preparing the liquid fertilizer:
Once the kitchen waste is generated and collected in a suitable size plastic
bucket, water is added up to its rim. The bucket is closed loosely and kept
outside in the open away from the kitchen and domestic area. It may take
around a week to get the liquid fertilizer from the waste when the
microorganisms developed in the bucket start decomposing the waste indicated
by a foul smell nearby the setup. Appropriate measures such as face mask and
hand gloves need to be used to deal with the liquid fertilizer under formation.

8. Collecting the liquid fertilizer:
Usually, the liquid fertilizer can be collected after a week which is the perfect time to collect as kitchen waste
contains ingredients with different composting life. If the experiment is performed in a hot arid place where the
temperature is high, the process may be quicker. It is advisable to stir the waste on an alternative day to help the
decomposing process to be faster. The liquid waste which is dark in color is collected straining through a mesh after a
few days. Dilution of the liquid by adding water of about ten times of its volume is done for making the liquid
fertilizer ready to be used. This will dilute the alcoholic content of the waste, if any formed during the process of
composting. The liquid is now rich in many nutrients and is useful as nutrient solutions for hydroponic system.
How Hydroponic works:
•Contrary to conventional farming, hydroponics does not use soil to grow food. This method involves growing plants
on artificial or natural substrates so that the roots may easily draw nutrients from a prepared nutrient solution. The
implementation of various hydroponic farming techniques varies depending on the type of plant, regional climate,
and financial constraints, among other things. The majority of systems include an aerator and a tank for the
nutritional solution, as illustrated in Figure 1.
•A nutrient solution is mixed into the water in the control room.
•From here it is pumped into troughs which house the net pots with the crops.
•Since the water directly reaches the roots, it is absorbed much better and much less water is required since nothing is
lost in the soil absorption.
•In this, the plants absorb the nutrients from the water and using sunlight they produce the yield.

9. Nutrient Film Technique:
The Nutrient Film Technique (NFT) system . suspends the plant over a continuous stream of
nutrient solution that cleans the ends of the plant's root system. The channels that hold the plants
are angled, allowing water to flow the entire length of the plant tray before being drained into the
tank below. After that, the water in the tank is aerated with air stones. A submersible pump then
pumps nutrient-rich water back from the reservoir to the top of the canal. The Nutrient Film
Technique System is a recirculating hydroponic system.

12. OUTCOME OF THE PROJECT :
The proposal will address food security for growing
population through the developed low cost hydroponic
system.
Achieving self-sustenance by growing vegetable crop in the
less space and attaining good yield with less water using
organic fertilizer.
The developed low cost hydroponic system will be the
urban farming solution.
