My Cental Heat&Air Unit runs off Natural Gas

I was Looking at my Heating and Air Unit . It runs off Natual gas. On one side of the Unit I have a what looks like a 3 1/2 inch PVC pipe running to a vent outside. From what I can gather this is a C02 vent . Could this be tapped into and a small line run into my grow room . THe question is : is there a certain amount that has to be introduced during flowering ? If so How Much? and is there a Meter that you can buy that tells the relative C02 level??
Thanks any replies.

It would appear as though you are correct, it is possible with the right equipment but just as expensive as buying a tank+reg. you'll need an o3 generator to convert carbon monoxide into Co2 and IMO it wouldn’t be very good for your health without it. Not only that it also puts out humid air + heat.

If you really want to do a Co2 enrichment, you have to buy a Co2 tank + regulator/meter.

Also, the proper amount of Co2 that is needed to super charge your garden is min 700 and max 2000 PPM of co2 (all depending on light, nutes, heat, water, stress, etc).
You cant know this without a meter, and the plants cant use this much if they aren’t getting the right amount of light + nutes.

Not to sound rude or anything, but it’s true. You just wont see the difference using other methods.

Also, you can do a search on google for the CO2 meters.

Here are just a few links:

You should get the idea.

be very careful if you attempt this. Carbon monoxide is extremely dangerous. People commit suicide by running hoses from their car exhaust into the passenger compartment. Same fumes same danger.
