Supplying Air to Roots When using co2?

So I have read that when using CO2 that the CO2 being inherently heavier than air can pool on the floor and suffocate the root system. Roots requiring O2.
Would it not then be advisable to perhaps run an air line connected to a pump into the root zone to ensure adequate O2 levels in the soil/medium?

This post is in reference to soil growing

I would think just a fan blowing at the rootzone would help plenty without need for an airpump. Just my 2 cents. I just got my first co2 bottles a few days ago and I'm waiting to get a regulator to use them.

I put an airstone in my pots during one grow. It seemed to do well with just that and no CO2, you can always try that.

*yup just have adequate air flow (mounted fans / blowers) to make sure there is no stagnant air

..ps.... drop the airstone ideas, thats just silly .2s

Lay down, if ya can't breathe and pass out, put a fan there. If you can breathe and don't pass out, its a-ok. I think it takes 15000 or 20000 ppms of o2 for you to breathe
