Does it hurt the plants to leave the fan always on?

I have my fan (Air Cooler) on 24/0. it is on low and it blows between the light and the top of the plants.
Is it OK to let it work 24 hours a day or should I turn it off?

if its to cool your lights then turn em with your light schedual....if it is your main circulation then leave it on 24/7

Im not sure but i was always told to keep things as close to real life cycle as possible, does the wind blow 24/7?

I keep my fan on all the time.

I keep mine on 24/7 it helps to keep the mold away

It is both, my main circulation and it also keeps the light cool. It seems like others keep it on all the time and it doesnt hurt the plants. I guess, I'm gonna leave it on since it doesnt hurt anything.

i would too if its your vent. i dont have that problem or heat so i just tied it into my system breezy during the day calm at night just like most days

I would say leave them on 24/7 that's what i do and it works just fine.

After all a bigger stem can only do more good.

Bigger stems hold bigger buds.

I left mine on 24/7, but not directly at the plant. I read that it creates strog stems, and prevents mold.

Yes, yet another good reason.

Good air circulation prevents mold from forming.

I too leave mine on all the time, on medium, with every grow. As others said, it makes the plant sronger, thicker stem, and it also helps keep flying bugs off them (not completely, but helps).

24/7 here no problems
