Nutridome is a collaboration between Siphiwe Ngwenya and Jessica Michelle Le Roux, the project set out to create a prototype of an affordable, hybrid hydroponic system which works off of an automated system which is connected to a smartphone application. The structure enables compact urban farming.

Introduction

The prototype considers SDG 11's call by the United Nations. The project speaks to being self efficient in urban environments by enabling urban living with with the ability and ease of use and use of a 'smart vegetable garden. The idea is for the user to self sustain their families through the use of a compact hybrid hydroponic greenhouse structure which produces high yields, provides nutritious foods and reduces transportation of food produce.


The idea in the design was to come up with an energy efficient solution which will enable plants to grow in varied environments. The prototype is a controlled system linked to remote system, envisioned to be accessible via a smart phone application which also includes a community engagement platform.

Materials

Tools

Step 1 - Linking the LED Lighting

We used 3 LED lights because we only had 9V batteries. This forced us to have an external power source that could cope with those power needs. To deal with 9V we decided to use a relay as a magnetic switch because the Arduino can only handle 5V and this is where the relay helped us. The Arduino code was written to play on a loop since we didn't have the required modules to communicate with the system.


The concept was created for the South African climate which has wonderful sunlight. The LED system is designed to be cost effective on resources and created as a back up where sunlight is not sufficient for plant growth.


Step 2 - Creating Hydroponic Pump System

This is a prototype illustration of the concept here is on a smaller scale. The dome design is capable of housing hydroponic vertical PVC piping 4ft tall with a centre barrel where plants can be cultivated in soil.



Step 3 - Creating the Shell Structure

This is a PVC pipe that has been drilled with holes we were going to use disposable plastic cups but we found some plastic growing cups in the store room and we used those. for this demonstration we are using an ordinary aquarium pump and pipes for the water flow. The bucket is just a normal bucket.


The dome was made from 25mm PVC electrical wiring pipes. The dome was inspiration for the idea as we saw it at the Centre and realised its potential. the PVC pipes are held together with cable ties, glue and connectors.


The shading is normal garden shade and plastic sheeting can be placed over the structure to create more controlled environments. This will be when you have put the hydroponic system with lighting inside the dome we just wanted to illustrate the look for the final product of the dome.


Step 4 - Setting up the Dome

The design is created to enable both a hydroponic system as well as vegetables that need to grow with soil. As the structure was designed to alleviate concerns with the rapid rate of urbanisation and expansion in years to come, the design was envisioned to be installed on cement or in a garden.


As you can see in the second illustration provided, plants can be placed in soil in containers in the centre and around the base of the structure surrounding the hydroponic systems.


Step 5 - Setting up the plants in the hydroponic system

In this step, the above steps were combined and the plants were placed into each tube with the roots left to dangle inside the PVC piping system.


The roots then feed off of plant nutrient water and without the soil, produce yields are at high rates and the oxygen flow is strong.


Step 6 - Why consider a hydroponic system

How you will benefit from the system

Water saving

more efficient farming is needed with under 1% fresh water available globally

Lowers the consumers costs


No soil

More attainable for urban living

More efficient on water usage without soil


General Benefits

  • Fast growth
  • Quick yields
  • Less disease
  • Less pesticides
  • Less plastic usage
  • Higher yields
  • Affordable
  • Less food transportation
  • More nutrients for the consumer
  • Educational within self sustaining food chain
