has anyone ever heard, or better yet seen this done. Ive recently moved and the growins on hold for the time being, but been readin, an read about using a co2 bottle with regulator and airstone intermittently in a dwc style (or any other where roots sit in the water) cant remember exactly what i read, but would be interested in tryin once were on again, ideas?

If your putting c02 in the water there will be less room for 0xygen, seeing as this is what roots need I dont see how it will help.

like i said cant remember exactly what i read but it was along the lines of co2 being absorbed through the roots, if say dwc then the air will be constant with maybe 30 second blasts of co2 every 10/15 mins

Again, roots dont absorb C02, the plant does, why not blast the plant with c02? Your trying to get as much o2 to your roots as possible.

Are you sure this wasn't pertaining to an entirely submerged plant?

^^^ yeah i think i read it some where while researching, and no not less o2 but intermittent co2 with the air pump still on maybe?, not sure really was drunk surfin lol, but im gonna give it a go once im settled in my new place cos i run dwc anyway ill keep ya posted

Aquatic plants absorb CO2 from underwater. Your plants will not, and they will not enjoy it if you start pumping your water full of CO2 bubbles. Stick to O2, and add your CO2 to the air that your leaves are breathing. They'll love you much much more.

What about if you have a dwc system and you get a Co2 bottle for the plants and then get an O2 bottle and put the line where your roots are?
