Kansas State High Tunnel Video Series
This video series was developed by Kansas State Research and Extension, and includes segments on the following topics related to commercial high tunnel or hoop house production:
Overview | Design | What to Plant | Basic Management Considerations | Intensive Management | Resources

Managing the Environment in High Tunnels for Cool Season Vegetable Production
Light, temperature, and relative humidity influence how crops grow and develop. With support from SARE, Purdue University Extension developed this publication, which introduces important factors to consider during design, operation, and daily management of high tunnels, and explains plant responses to the environment.

Developing an Energy Efficient, Solar-Heated Greenhouse in Maryland
This project investigated the effectiveness of energy-efficient greenhouse design and the ability of water-heating solar panels to heat a greenhouse as a propane alternative. Download File (695.90 kB)
Greenhouse Energy Conservation Strategies and Alternative Fuels
Includes curriculum materials, extension bulletins, resource lists, and a greenhouse energy model that were developed with the intention that educators can use the materials in full or part to deliver programming on energy management and conservation for greenhouse production.
