So solli Master...and I appreciate your input as I do others...but what you just suggested was that a plant could survive with no oxygen. Just CO2.

A plant uses light, water and air to survive. Air is comprised (roughly) of 78% Nitrogen, 20.5% Oxygen, 1% Argon, .5% Carbon Dioxide, and traces of 13 other compounds. If you took out all the Oxygen it wouldn't be air and the plant wouldn't survive, just like every other living thing on this planet.

So I'll disagree with you. Plants do 'breathe' Oxygen as it's a part of the air they have to have to survive.

But that brings up another question. If a plant has to breathe the components of air as part of the formula for survival and one of them is CO2, why does it increase the growth of marahoochi when you supplement the grow area with CO2? Would the same result happen with increased Oxygen levels? Or Nitrogen?

shhhh shhhh shhhh (sound of me floating across the rice paper)
