Strong smell at night

What’s happening everyone, quick question that I’m sure you all have experienced, or maybe not and it’s just me. My 2 girls are about 35 days into flower and seem to get really strong in smell about 30 minutes after lights out. I mean the smell is strong during the day too, but at night it gets really strong. No I don’t have a filter as I’m not worried about the smell getting out, and maybe this is why some never experience this nightly increase in smell.
Feel free to chime in.

Well your humidity will go up at night, might have something to do with it.

Are you venting intermittently?

After lights off photosynthesis stops - respiration starts.

I’m venting 24 hrs a day. I don’t use a closed loop system, or sealed tent. I just take in fresh air from the bottom Velcro flap. Yes, humidity does rise at night, but I have a good sized dehumidifier that keeps things pretty under control never allowing the humidity to pass 50%. I’m leaning more toward respiration as the culprit. Just trying to see if anyone else experiences that nightly stink.
