Too much carbon dioxide?

[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?
Ideas?

Yes it can...1500 ppm is what you are shooting for. anything over that is a waste and anything that moves the ppm level over 2000 can be fatal for the plant.
