1 Project Purpose

The purpose of this project is to ensure sustainable local food production units and adresss:

  • Common nutritional deficits in food desert areas.
  • Rising food prices resulting from food distribution, processing, packaging, and storage, effectively cutting out the middle man.
  • The time consuming, intensive nature of more traditional gardening techniques for personal produce production

2 Basic Concept

/The-Kratky-method-system.png

The Kratky system is a zero power required system which relies on a plant’s root growth down towards a lowering water source to develop oxygen absorbing roots instead of keeping them at the same level of water like other systems.

Note

The following are similar water suspended growing systems and how they compare to the Kratky system

Systems Difference from Kratky
DWC -Requires power
Aquaponics - Requires power and fish as nutrient source
Wick - requires wick material for each plant, not vertical, and doesn’t encorage root growth. + just as easy as Kratky, and doesn’t reuiqre energy
Ebb and Flow - expensive to buy, hard to improvise, and requires energy. +: good for large scale production
Nutrient Film Technique The exact same as the Ebb and Flow execpt -: requires an oxygen stone, harder to properly tune. +: distributes more oxygen to plants, making roots much healthier.
Continuous Drip -:requires contstant energy to supply plants with water. +: keeps roots healthier

The closest similar system is a Deep Water Culture (DWC) system. This system requires power to run an air pump to constantly oxygenate a fixed volume of water.
