@The_Dude You said you run 4qb's and 600 watts in flower, how much area do you cover with that? About 4 of the cob's I run are equal to about 1 QB288. So I guess you could say each one of my 4x8 tents is equivalent to running 8 qb's @1500+ watts. I also run co2 at 1200ppm but I recently kicked it up to 1500ppm. I don't think it's dangerous at all, there is some misinformation out there about co2, it takes over 10,000ppm to have any effect on humans...
Normal CO2 Levels
The effects of CO2 on adults at good health can be summarized to:
- normal outdoor level: 350 - 450 ppm
- acceptable levels: < 600 ppm
- complaints of stiffness and odors: 600 - 1000 ppm
- ASHRAE and OSHA standards: 1000 ppm
- general drowsiness: 1000 - 2500 ppm
- adverse health effects may be expected: 2500 - 5000 ppm
- maximum allowed concentration within a 8 hour working period: 5000 - 10000 ppm
- maximum allowed concentration within a 15 minute working period: 30000 ppm
