About Urban Agriculture Series: Hydroponic Foundations

Instructor: Tyler Ree

The Urban Agriculture Series with HAPI

Join the HAPI program at the Columbus Idea Foundry, and learn about how to grow sustainably in an urban environment with hydroponic gardening. Each class covers some basics and then focuses on a specific growing technique. Students will also learn how open source automation capabilities can be leveraged to scale and simplify the techniques.  No experience is needed and beginners and those just curious are welcome!

Register for one installment or for the entire series at a discounted rate.  

Thursday, April 2, 6:30pm. Flood & Drain Systems

A brief overview of hydroponics is followed by an in-depth, hands-on build session. Students will work together to build a production-ready flood and drain (F&D) table. Once the class is complete, the student-built F&D table will be used to grow food for a local charitable organization. 

Class Topics
  • Bell Siphon (Auto-siphon)
  • Theory and Construction Flow Modulators in a Flood and Drain System
  • System Maintenance
  • Planting density and timing
  • Designing, Cutting and Assembling PVC frameworks
  • Working with Rockwool and LECA





Tuesday, April 7, 6:30pm. Wastestream Bioconversion with Black Soldier Fly Larvae

Black Soldier Fly Larvae (BSFL) represent a fascinating approach to wastestream management. An active colony of BSFL can process incredible amounts of bio-waste (e.g. kitchen scraps) per day!

This class teaches you how to apply BSFL cultivation to reduce the waste stream in your home or business. Students will create their own small-scale systems for raising and propagating BSFL on their own. Small quantities of BSFL will be available at low cost ($8) for students who want to get started as soon as they get home from the class.

Class Topics
  • BSFL Theory and Applications in Wastestream Management
  • Black Soldier Fly Lifecycle
  • BSFL Husbandry – Raising BSFL for Fun and Profit Beyond Buckets
  • BSFL Systems Design
  • Scaling Up – Zoning and Regulations



Thursday, April 23, 6:30pm: Nutrient Film Technique

Learn how to grow food anytime, anywhere using Nutrient Film Technique (NFT). A brief overview of hydroponics is followed by an in-depth hands-on build session.

Students will work together to build a production-ready NFT system. Once the class is complete, the student-built NFT system will be used to grow food a local charitable organization.

Class Topics
  • NFT Theory and Construction
  • Water Management in NFT
  • NFT System Maintenance
  • Planting density and timing in NFT systems
  • Designing, Cutting and Assembling PVC frameworks
  • Working with Net Pots, Rockwool and LECA




Tuesday, April 28, 6:30pm:  Sensing Your Environment

Awareness of environmental factors is important for people working in robotics, hydroponics, environmental science and many other areas. In this hands-on class, students will work with 6 different types of sensors. The class will show how various sensor communications protocols (e.g. SPI, I2C, 1- Wire) can work together to create a useful and informative picture of the environment in which they are placed. Follow-on conversations about controlling assets in response to sense values as well as data visualization will be encouraged. 

The instructor will provide students with Arduino Mega 2560's and all necessary sensors for the duration of the class. A parts list will be made available upon registration should students wish to buy and bring their own hardware.

Class Topics

  • How Sensors Work
  • Common Sensor Interfaces (e.g. SPI, I2C, 1-Wire)
  • Hands-On Sensors: Temperature, Humidity, Soil Moisture, Light Intensity, Conductivity, Barometric Pressure
  • Approaches to managing wires and interconnects 
  • Power Considerations

Thursday, May 14th, 6:30pm:  Vertical Aeroponic Systems 

Learn how to grow food anytime, anywhere using Aeroponics. A brief overview of hydroponics is followed by an in-depth hands-on build session. Students will work together to build a productionready vertical aeroponic system. Once the class is complete, the student-built aeroponic system will be used to grow food a local charitable organization.

Class Topics
  • Theory and Use of Vertical Growing Systems
  • Vertical Aeroponic Systems – Construction Techniques
  • Planting density and timing in Aeroponic Systems
  • Aeroponic System Maintenance
  • Designing, Cutting and Assembling PVC frameworks
  • Working with Net Pots & Rockwool
