Default How much CO2/W of light do plants need?

Does anyone have any thoughts on using a sealed and cooled space that doesn't vent externally? CO2 would be artificially supplied, but how much? Does anyone know a plant's rate of respiration?

CO2 Calculator - Greentrees Hydroponics This is the coolest thing I've found and the recommended level is 1500 PPM. Good luck

don't forget to factor in 300ppm co2 in the air already... Co2 injection should be injected in a semi hot room 85-90 deg for the plants to soak up a good amount..

You know that is what i have always heard. When you watch Remo the "Urban Grower", he states 78 degrees, 40% humidity and 1800ppm Co2.

hmmm. Hot or Not?
