I am running a AC cooled sealed room set up. Propane CO2 burner is controlled by a Sentinal CHHC-4 and obviously set to not run during night cycle. I have the CO2 set at 1250 with a 250 threshold. During the day everything operates great. CO2 fills up and is slowly used by the plants. It clicks on every couple hours fills back up and repeats.
Im concerned that at night the constant CO2 is around 1800-2000. Is this just the plants off gassing the CO2 during night cycle? It seems very high to me. From what I have read CO2 at night isnt going to do damage but im just wondering is it normal for the plants to put off this much C02 at night. Is it possible its a Sentinal Calibration issue?
I should mention I am battling root aphids right now and about 30% of the plants have been slightly damaged. Aphids (i think) are all gone as of yesterday.
Any thoughts would be appreciated.
