CO2 & ebb and flow

[steelyeyes]

I've got this ebb and grow thing dialesd in and it's time for the next step...CO2

I have some questions, one is about the root zone. Roots are all about O2 and since you only flood them with oxygenated water a couple to a few times a day (6 or more for me) the rest of the time wouldn't they be exposed to the high CO2 atmosphere that the rest of the plant is? Does that cause any issues?

I'm sure there are other things to worry about like the plants gulping down more nutes to support the increased growth rate too.

Any insight into the things you have to do differently to succeed with this stuff would be much appreciated.

Plants live for CO2 and their by product is O2, which in reference they will eat more nutes since they are breathing better. Its like giving an asthmatic their inhaler when they have trouble breathing, but like anything too much of anything is bad....
