Fan at night?

Would it make any difference to have a fan running at night during flowering?

I have a tabletop fan running during the day, mostly to blow my CO2 (from yeast bottle) toward the plant. Since there is no photosynthesis at night, would it do anything?

make it stronger. I go by the idea that if you leave the fan off at night during flowering, it'll help it to produce more resin because it's not being inturrupted by the wind. I don't know at all the accuracy of that, it's just something I like to think.

correct me if i'm wrong but i thought it was smartest to be releasing c02 without fans on.

CO2 at night doesn't matter as plants use oxygen when the lights are out. Make sure your fans are oscillating fans because otherwise you can get windburn on the leaves. These are not exhaust fans , so they shouldn't affect CO2 levels, but at night you should make sure there is a little fresh air to supply more oxygen as they need more at night. Also they need a cooling down at night just like nature does (not cold,just cooler). Resin production is not affected by no breeze at night, but MOLD PRODUCTION should be less with a breeze.(like nature) The healthier the plant, the more resin grows.

CO2 is heavier than air- so you would want some agitation of the air to get it up to the plants so it doesn't sink to ground level.
Was just reading about it in another post.. will try to link

i run the fan at night especially when budding, i mean think if you have damp air just hanging around its ideal conditions for mold, i run them constantly
