CO2 and PH drop - tweaking sealed rooms

[True Blue]

just to chime in, my PH rises... 1500ppms....constant. pumps in room
i have to add PH up when i mix a new batch of nutes (drops to 5.5) i let mine sit on 5.9-6.0 the adjust back (maybe every 3-4 days) once it goes over 6.4

heres 5 days growth!





great thread fellas!

Oh, Coolx..... I tried e-mail and calling on why that product could be used without air but never a response to the e-mail and just song and dance on the phone. I wouldn't use the stuff and if I did it would be with air.

Peace
