Here, we explain how plant-growth parameters interact with carbon dioxide content in grow room air and how cultivators can best apply this knowledge to their commercial cannabis production facilities or research programs.

How Does Carbon Dioxide Enrichment Affect Environmental Control?

Gretchen Schimelpfenig, PE, is the Technical Director of RII and manages the organization’s Technical Advisory Council. She is an LED-lit home cultivator. While serving Burlington Electric Department customers, she incentivized horticultural LED lighting equipment through energy efficiency programs, and has commissioned LED lighting designs and installed systems in commercial and industrial buildings, including greenhouses used for academic research on hemp and other cultivars. She authored the RII
