[smokemonster]

Keep fan on or off during dark period?

 

[smokemonster]

no one? what do you do?

 

[rocpilefsj]

I like to keep mine on to ensure that my girls are getting constant fresh air, they need it even if the lights are off.

which fan? inline fan or oscillating fan? intake/exhaust fan? depends on which it is.

 

[Dalek Supreme]

Lights off/fan off no probs for me.google your question and you can weed thru for your answer.

Depends on which fan and your needs. I leave my exhaust on 24 hrs a day. I have 1 room fan that goes off when the
light goes off and another that gently moves air around 24 hrs.

 

[smokemonster]

i was talking about the oscilating fan.

It's more important to keep the exhaust on at night to reduce the humidity, which build up in the dark period. Fans are helpful too, but not as effective.

 

[Barrelhse]

I leave the fan on 24/7. It reduces the risk of budrot and keeps the leaves from getting swamped by the gases they exude.

 

[ScoobyDoobyDoo]

yea, keep oscillating fans on all the time.

 

[yesum]

I vote to keep the exhaust fan going for humidity and general health.

 

[BlueBalls]

I keep the oscillating and exhaust fans on 24/7.
The exhaust fan I have hooked to a Titan Mercury 4 so it slows down a bit during the dark cycle when the temperature drops.

 

[missnu]

everything for my grow goes on and off with the timers, unless I am running my cloner..but no, I don't use a fan in the dark period

 

[drive]

off let them rest they don't want to hear that racket all night

 

[Ringsixty]

i leave my exhaust fan going 24/7 and my tent fan turns off when the lights are off. no problems.

 

[chrishydro]

24/7 blowing the air around the plant not right at it, very important. Let the girls sleep.

 

[Guitar guy]

Exhaust on all the time. Don't have an oscillating fan.

 

[colonuggs]

you want circulation 24/7... I leave my exhaust fan 24/7 too

 

[marc88101]

off let them rest they don't want to hear that racket all night

Huh???....leave all fans on 24/7 throughout the entire grow..your plants need the fans for a few reasons..fresh air exchange and the wind on them help build a stronger structure..

 

[polyarcturus]

doesn't matter, really you should leave the fans on to exhaust the gas they exude and lower the temps to help them flower. i turn off my oscillating and leave my exhaust on at night.(actually it only come on 3x at night for about 2 hours ea.)
