For a variety of reasons I am not able to buy the Cozir CO2 sensor. However, I could get this MG811 sensor.
The original Cozir is measuring [0 , 5000] ppm, while this MG811 range is [350 , 10000]. I want to know if this range is useful - I'm particularly worried about the minimum 350 ppm. What are the values we should measure for growing plants?
One author says "Most gardens and crops will benefit significantly when the concentration of available CO2 is kept between 1000 and 1600 PPM" ("How to Hydroponics" - Roberto, 2003, p.39)
