I've always considered keeping the elliptical in the grow to do cardio and fill the room with co2, those machines are just too damn big.here's the fun part about IEQ testing (indoor environmental quality)... which is commonplace in HVAC
its given us some baseline numbers to work from...
Heres a calculator you can use for CO2
- 250 - 350 ppm - background (normal) outdoor air level
- 350- 1,000 ppm - typical level found in occupied spaces with good air exchange.
- 1,000 - 2,000 ppm - level associated with complaints of drowsiness and poor air.
- 2,000 - 5,000 ppm - level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
- >5,000 ppm - this indicates unusual air conditions where high levels of other gases could also be present. Toxicity or oxygen deprivation could occur. This is the permissible exposure limit for non-prolonged daily workplace exposures.
- >40,000 ppm - this level is immediately harmful due to oxygen deprivation.

My real point is, if you live with your grow, adding CO2 is a waste of $...
theres a reason they used to say that plants liked to be "talked to"
the average adult’s breath contains about 35,000 to 50,000 ppm of CO2, exhaled in short bursts over time.
