There are 5 steps in Design Thinking Process
- Empathy
- Design
- Idea
- Prototype
- Test
What is Empathy ?
Empathy is first important step of Design Thinking Process. Empathy means to understand the problem faced by the people. Through empathy we are able to put ourselves in condition of that person and connect with how they might be feeling of their situation.
Way to Empathize :-
1. By talking with that person.
2.By observing the problems faced by the person.
3.By doing the actual work and experiencing the problems.
Prasad sir assigned us task to find out information about Hydroponics.
About Hydroponics:
The cultivation of plants in nutrient-enriched water, with or without the mechanical support of an inert medium such as sand, gravel, or perlite is called hydroponics. Also called as soilless farming.

Types of Hydroponics :-
1. Flood and drain system
2 NFT
3.Deep Water Culture
4.Aquaponics and Aeroponics
5.Wick Culture
Lecture by Dixit sir on Solar Thermal, Photovoltaic and Photosynthesis.
Solar Thermal energy:
Form of energy which stores solar energy to generate thermal energy to for use in industry, and in the residential and commercial sectors.
Photovoltaics:
Photovoltaics is the direct conversion of light into electric power .
Photosynthesis:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Next day we did nutrient dosing to the brinjal crop. Nutrient dosing should be given only once in a week and soil extract and sugar solution should be given daily.
TITLE:- Hydroponic Cultivation in 3 Different solution
Objectives:-
1)Modification of the old hydroponic system.
2) Maintenance of the old hydroponic system.
3) To convert old hydroponic system into Flood and Drain hydroponic system.
Background:-
Hydroponic:-
Hydroponic system is a soil-less cultivation method. It can be used to grow plants in a nutrient rich , water bladed solution.
In this method of cultivation, roots of plants are suspended in water so that roots.
Hydroponic is a way to skip the soil, sub in a different material to support the roots of the plant, and grow crop directly in nutrient rich water.
The added benefits of controlling and managing pH, CO2, heat, air movement, nutrients supply, water needs, temperature and lighting scheme, help farmers boost production of their crops.
Advantages:-
1) No soil involved
2) Optimal use of location
3) Control over climate
4) Save water
5) Optimal use of nutrient
6) pH control
7) Fast growth rate
8) Zero weed
9) Time saving process
Methodology:-
1) The term hydroponics was derived from the Greek word hydro means water and ponos means labour and literally means water work.
2) We have to construct a hydroponic structure which would consist of 3 different layers with same plant (Spinach), and 3 different liquid (Chemical fertilizer, Vermiwash urine fertilizer, vermiwash by bioslurry) should be taken and then growth of plant could be studies.
3) first we dismentled the old structure.

I have brought Brush, Thinner, Polish Paper & Paint from Pabal Village.
Using the Polish Paper on Dismantle old hydroponic structure before using Paint.
Cleaning structure of old hydroponic system:
Painting the old Hydroponic Structure:
03-08-2022
I have Cleaning the pipe of previous system so that mud should be removed before we use pipe.
I have discusses with Dixit Sir on our project topic to fill Google form between Objectives, Methodology, Background.
04-08-2022
Today I have Cleaned the PVC pipe.
Painted the PVC pipe before the connecting on hydroponic structure.
Connect the PVC pipe on hydroponic structure:
05-08-2022
Today, I made outlet & inlet for the system. We went to the village to buy elbow & T we found 3 buckets & adjust the system properly.
06-08-2022 to 09-08-2022
I have planned & placed inlet & outlet pipes for hydroponic system, dripper pipes are used for that.
We shifted the system near polyhouse & assembling it properly, we also brought 3 pumps and started electronic work on it.
10-08-22 to 15-08-22
We Worked on the flood and drain Hydroponic system which was in the Polyhouse, but the system was not in operation since the open house in Vigyan Ashram and the Brinjal plants were dying. So we got assigned to start the system before the plant die.
We check the system and then the electric supply, then we started the flood and drain system .
We were also assigned to prepare Nutrient solution for the brinjal plants so that they get into good health as soon as possible.
Nutrient solution :- For 30 lit
K2SO4 2.25 gm
MgSO4 1.9 gm
NH3 1.6 gm
H3PO4 3.7 gm
We also shifted our system from workshop to a permanent place near polyhouse , First our plan was to shift it to polyhouse but due to height of our system that plan got deleted.
we shifted the system and then leveled it with the help of level tube.
After that we attached all the motor to a single wire.
16-08-22 to 21-07 22
Finding information on hydroponic system :-
>Content of Urea
>Nitrification Reaction ( as plant can use only NO3, NH4 from urea ).
>Title of our project
>Objective of project
>Background of Project
>Advantages of Hydroponic
>Disadvantages of Hydroponic
We decided to plant spinach plants in whole system. So found some information on Spinach.
Information on Vermiwash composter by urine method and Vermiwash composter by bioslurrry.
22-08-22 to 23-08-22
We did coding of Arduino sensor, checked it and connected to the hydroponic system.
we set the timing on Arduino sensor, it will run for 15 min and take a pause for 1 hour.
24-08-22 to 25-08-22
We had to prepare a chemical / Nutrient solution and check its PH and TDS.
WE got the PH very less (4.3) so we decided to add ammonia (NH3) to increase its PH.
As most of the chemicals were over, we went in Pabal village to search for those chemicals.
26-08-22 to 30-08-22
We connected the whole system, but there is a problem the water in the pipe is at low level and is not touching the cup,
So we have three options:
Some changes in design, changing the cups or putting breaker so water level rises.
option 2 (using different and deeper cups is suitable) and option 3 (putting breakers in the system).
Calculations for selection of reservoir so that the motor doesn`t run out of water. So that the motor remain submerged when the water in the pipe rise to 2 inch height.
31-08-22 to 03-09-22
1)Vermiwash composter by urine method:- Vermiwash is an organic drainage obtained from units of vermicompost. The water that contain some amount of urine passes through the vermiculture, resulting in washing of the live and dead earthworms, soil microorganisms and decomposed organic matter, carries all the dissolved substances. It is rich in dissolved nutrients and amino acids and therefore, is a good source for plant nutrients in organic agriculture.
The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day
Urea:- It can be used as a chemical fertilizer. Of course, ammonia can also be processed into various nitrogen fertilizers and nitrogen-containing compound fertilizers. It is an important basic raw material for inorganic and organic
Urea Fertilizer 1 Kg Soil Manure (1 Kg Granules)
Original Price =₹130
Our urine contains significant levels of nitrogen, as well as phosphorous and potassium. The relative ratios are typically around 11 parts nitrogen to 1 part phosphorus to 2.5 parts potassium. Americans produce about 90 million gallons of urine a day, containing about 7 million pounds of nitrogen.
2)Vermiwash by bioslurry method:-
A) it acts as biofertilizers, restores soil nutrients, stabilizes soil, and enhances soil fertility at a long-term period.
B) it attends to social issues and recycles waste.
C) it is shown to be a profitable enterprise as a circular economy.
3)Nutrient solution :- For 30 lit
K2SO4 2.25 gm
MgSO4 1.9 gm
NH3 1.6 gm
H3PO4 3.7 gm
04-09-22 to 09-09-22
In discussion with Dixit sir we decided that instead of making NFT hydroponic system we will make Flood and Drain system.
so all those problems that we were facing ( low water level, fast movement of water, larger cups) all of those were solved.
Dixit also told us to learn and apply siphon system in our hydroponic structure
So we started our study on siphon system and the new design & planning of Flood and drain system
we decided the flow of water which would be like the hole from where water which was exiting from the system is now the inlet of the system, the water will enter the system from the previous outlet with the help of motor which will run foe 2 min 30 sec (time taken to fill the pipe ) then the system will shut down and water will come back into reservoir with the help of siphon system and by the inlet itself, system will run after every 2 hrs.
we also planted the spinach plants in cocopeat media so we could place the plants in the system .
After plantation was completed all these cups were placed into the system .
13-09-22 to 17-09-22
we removed the ardunio from the system which had a code for 15 min and it would be shut for 1 hr according to the previous NFT system requirements but now it has to be change according to Flood and Drain system.
so we removed the Ardunio and started its coding
We found the algorithim of ardunio:-
And the codding done :-
int motor1 = 4;
void setup() {
Serial.begin(9600);
pinMode(motor1, OUTPUT); // Set pin 4 to output
}
void loop()
{
digitalWrite(motor1, LOW); // Set pin 4 as “low” or turn it on
Serial.println(“Relay on”); // prints that the pump should be on
delay(150000); //150 second delay
digitalWrite(motor1, HIGH); // Set pin 4 as “high” or turn it off
Serial.println(“Relay off”); // prints that the pump should be off
delay(7200000); // 2 hour delay
}
We placed the Ardunio into the system after completion of the codding.
18-09-22 to 24-09-22
We had a observation that due to continous rainfall it had affected plants growth.
Due to over irrigation and very good water holding capacity of cocopeat the plants started to burn. Spinach do not need lot of water.
So after discussion with Dixit sir we decided to change the media from cocopeat to small pieces of brick.(as it has low water holding capacity and contain large number of pore space between them.)
We also collected all the different liquids ( chemical water, vermiwash form urine method, vermiwash from bioslurry method), near our system.
