A while ago, co2 levels were 100 ppm. Now they are 300 ppm. They were once twice that, when our oil and coal were being made. Cannabis and other typical c-3 plants can take up to 1000 ppm or more co2. This may require serious humidity, but from a recent trip to Virginia, this is no problem in many environments. They can take up to twice the photons and a lot of nutrients if given well regulated hydro.

Well regulated. The Supremes figured out :-) that the second

(1-13 an 14-latest) applies. Its not just states that can't own slaves,

its everyone. Same with language, assembly, or arms.

Hang the dissenters.

Thought of this last night.

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.
