it immediately occured to me how much co2 some growers are exposed to when they're adding it to their grows.
i know some of these people can't afford any loss in their cognitive abilities......
abilities begin to become impaired at 945 ppm, and dropped by 50% at 1400 ppm. the typical enrichment range is 13-1500 ppm.
i begin to question the safety of co2 enrichment.
