So you are basically injecting air richer in O2 into your system?
Have you used venturi valves/injectors? I have injected bottled O2 into a system with great success.
I am all for increasing O2. But I would never run @ 82F. Trust me if you get Fusarium wilt you will never run in the 80's again. "The slaughter" I call it.
Very much strain/pheno dependant. I have one pheno that will not tolerate 76-78F. Roots must have higher O2 demand than others. They start yellowing at 75.
I hit 70's when I have equipment faliure. Othewise it's 62-65 and O2 rich. Even 55F in winter which I love. I run open reservoirs in my cold air mixing room. I use about 3 times as much air as most. As such enrichment is attractive.
What is the O2 partial pressure being generated? Meaning how much higher than atmospheric?
Do you have any grow threads? I am also thinking to inject pure O2, but it still needs metering, no?
