lack of CO2 symptoms?

[Mainely Growing Weed]

What happens to a plant if it doesn't get enough CO2? Can anyone describe the symptoms? Maybe point me to some pics?

All depends on your grow area but plants can survive on very low amounts of co2 but it decreases overall yeild all depends on how many plants u got. but the more co2 a plant gets the better and bigger it grows.. some pictures would help

Been a long time since I looked at that.

Plants can eat up the co2 in a closet in an hour or so. They don't look bad they just quit growing and maturing and stay the same on what little they have.
I think the atmosphere's co2 is like 300 ppm. No more than that is going to help unless you fix the conditions of your room to help the plants use it. Your room must be like 95 degrees, flooded to 1500 ppm for 4 hours flushed with fresh air and flooded again.

If you go with co2 enrichment REMEMBER CO2 is an orderless gas and can flood a room or house and kill all animals including yourself. Please be carefull.
