Bubblers and CO2

[fhydro]

Hello, i change my therad to another forum, because of no answer. Maybe i will have more success.
Yes, i want to add co2 during the daylight period, using CO2 bottles and adding it manually. But i use DWC bubbler systems. And my air pomps take the air of the grow room. I'm scared of the possible side effect that the CO2 go to the roots with the air provided by the air stone. Are some of you with that experience ? Any ideas ?
Thanks

You will not have any problems the roots not only like the oxygen in the air it's really the CO² they like the most. Plants make oxygen and use CO².

That's my 2¢

how much co2 does it take to have an effect?

Holding the level around 900 - 1200 PPM for about 6 hours at a time is normal. Levels below 900 don't show as much improvement. But anything over 500PPM for an extended period of time will help.

I am new to the hydro growing methods, but would like to get my feet wet. :) I have read alot and did alot of research on hydrophonic growing. There is just one thing I don't understand and that is on the seedling or clone. How does the roots grow down to the resoivor when their just starting. Do they automatically know where the water is or does gravity just make them go downward to the resoivor. Or are you suppose to keep watering them slightly until the roots grow in between your rock mediums.
For example this peat pellet is at the top of the rock medium and I'm sure the roots aren't very long to reach the resoivor. http://www.overgrow.com/image.php?topic=1&articleid=22&imagename=soilvshydro05
Just copy and paste.
