jc1; co2 is it as good as people say

using co2 is it as good as people say does it improve yeild and thc

I have heard it can increase yield up to 50 percent, and its a fact that plants can absorb 7 times the amount of co2 commonly found in the air.

Co2 to a grower is like a hot cam to a race car builder. If all else is dialed in it will increase yield (not by 50% though). The thing is that in order for co2 to make any difference your grow space has to be optimal in many other areas. You need a sealed room with fan controllers and higher temps etc... If you do not have advanced knowledge of how co2 can help and how to use it you are better off spending your money elsewhere.

thanks for info
