This is some really good info on C02

Was wondering---
I am running a carbon filter all day, it runs through my light and the to exhaust. My temps are right at 75-80 ontop the canopy and 5-6 degrees cooler below the canopy.

Do you think I need to runn CO2... will i see great improvements on my budding.




:::Only reason I had mentioned that he flush the whole tank.... If there is too much salt build up on the roots then they are not going to take any nutes even if you dilute them. It happened to me last grow and I freaked out. Had to dump 50 gallon res and flush nutes. Now I know all i had to do was use a 5 gallon bucket and switch hoses , but a ebb and flow is a bit diff the a DWC or Aero:::
