Temperature: The best range is above 85 and below 95 degrees Fahrenheit with CO[SIZE=-1]2[/SIZE] injection. Some experiments indicate that maximum growth rate occurs at around 95 degrees with CO[SIZE=-1]2[/SIZE] at 1500 ppm. There are other experiments that indicate that CO[SIZE=-1]2[/SIZE] enhancement does not do much for the growth rate below 75 degrees. It is also recognized as a good practice to keep the temperature below 85 degrees if the ambient air is being used without CO[SIZE=-1]2[/SIZE] enhancement.
