excess co2

[2wheels]

I just installed a co2 generator in my 10x10x9 ft room and have a sentinel controller. At night the controller reads "hi co2". The last 2 nights I just shut it off but as a result it only gets turned on for half of my veg period. "hi co2" on my controller is + 2500 ppm and I am uncertain how high it actually gets. This is created solely from the pilot. I have a completely sealed room o as not to annoy my neighbors, this is a small legal medical grow, so i have no ventilation other than my sealed lights.

Can the "hi co2" harm my plants?

Definitely need to get some fresh air in there somehow. And yes, if your Co2 level is too high for an exteneded period of time it will hurt them as well as be costly to you. You want your Co2 ppm to be around 1200-1500 tops, +2500 is obviously over twice that. Best of luck to ya.
