It is the commercial, indoor, winter greenhouse industry, with 
absolutely nothing to do with GW and outside growing in the "real world."

However, it is an excellent starting point to give one insights into the 
impact of CO2 additions on plant growth. Lots of measurements and true 
facts, and real science.

Best wishes,

Kevin
