​Information below focuses on how light, air and temperature affect crops grown in greenhouses and other controlled environment facilities.  More specific information is available under drop down menus that focus on what crop type you are growing.

Environmental Effects on Plant Growth:
Regulation of crop growth and development based on environmental factors (Heins, Liu and Runkle. 2000).

Carbon Dioxide:
Interaction of CO2 and environmental factors on crop responses (Heins, Karlsson, Erwin, Hausbeck and Miller, 1984)
Day and night temperatures, daily light integral, and CO2 enrichment affect growth and flower development of Campanula carpayica 'Blue Clips' (Niu, Heins, Cameron, Carlson, 2001).
Supplemental carbon dioxide: a summary of its benefits (Schumacher and Heins, 1981)

Humidity:
Greenhouse humidity control (CropKing, Inc., 2017).

Ethylene:
Preventing ethylene damage in the greenhouse (Jones)

Thermomorphogenesis
Thermo- and photomorphogenesis (Moe and Heins)

Photomorphogenesis:


Photoperiodism:
Determination of photoperiodic response group and effect of supplemental irradiance of flowering of several bedding plant species (Erwin and Warner, 2001).
