I grow in cold climate and need to run a large l.p. heater for most of the night and my co2 levels reach 4000 during the nighttime ,and 1500 during the daytime , is this too high at night for flower?

4000 is to much at night anything over 2000 ppm imo. Make sure you aren't using co2 at night, plants only use when lights are on.

Sounds like your using a burner for heat and co2. You may need to use a heater at night vs the burner to keep temps up and in check.

I'd use another heat source for lights out then. Plants dont use co2 at lights out, and in not positive if a high ppm would harm plants during that time.


Also, from my readings in the past couple months, A LOT of burner growers were having flame issues and not getting a clean burn, thus the plants were showing major signs of issues. Keep and eye out for that nice clean burn. If not, clean out the tip. I think that was the fix.
