Room: 3x3x2 m = approx 20m^2e7 ccs.
Each breath: 20% O2 replaced by 10% CO2
Breathe: 100ml, so 10ml breathe
x 20 / min
200 ml CO2 per minute.
Room is 2e7 ccs, to get .1% need 2e4 ccs.
2e4 / 2e2 = 1e2 = 100 minutes of breathing in an uncirculated room,
to give 0.1 % CO2. Natural 2010 CO2 levels are .01 CO2 or so.
So, chill with your plants, listen to music, exhale.
Also, foliar spraying will allow them to open their stomata and you don't have to wait for
root to leaf transport.
Awesome plant.
