Adding CO2 to your WATER will drop the pH precipitously.
Remember, ROOTS like oxygen. LEAVES like CO2.
It's not that you have to be here a while, it's that you have to wait until someone who can answer logs on.
stinkyattic Reviewed by stinkyattic on . direct c02 injection for hydroponics I currently have a large areated, constant cirrculating d.w.c. system with sod. and hal. lighting and c02 on a burst timer....Does anyone know if you would bennifit from injecting c02 directly into the growing tubs, or whould the highly areated water defeat the purpose.....or do plants only process c02 via. foilage?.:smokin: Rating: 5
