humans exhale CO2 as a by product of breathing, plants use CO@ as we use O2, to live. Plants exhale O2 and take in CO2 to make food such as chlorophyll for photosynthesis (spelled right the first time so ya know )

What you need is a CO2 monitor, go to ebay and type Sentinel CO2 monitor, they make some that turn on humidity devices to control humidity, temp and CO2 PPM levels, (AKA and Environmental Controller).
What it does is turn on/off an onboard power outlet depending on your programming. You'll want to set your PPM level to 1500 minimum, not above 1750ppms. Place your CO2 monitor at canopy. What you also need is an electric CO2 tank regulator that when power is supplied, it opens up the CO2 tank which you also need.

High End Sentinel CHHC-1 Environmental Controller 550$
CO2 Tank Regulator around 125$
20-30 lb CO2 Tank 30-40$ a month to rent and have filled.

Some people buy CO2 Generators which are natural gas powered, some by propane tank which might last longer than a CO2 filled gaseous tank, you may prefer it. The make water cooled CO2 generators. Make sure you get the right size equipment for your growing area. Specifications should be listed on the equipment.
