    Im curious to what fellow blades do? Do you run them on a timer or 24/7 or not at all.

    If you dont vent you will smell. Itll seep out. And your plants wont like the RH going RIGHT UP. Run it 24/7.

    Dont water during lights off.

    I usually keep my fans running that blow over the plants but my exhaust fan is on a separate timer that runs for 30 minutes after lights off and comes back on a couple minutes before lights on.

    24/7. I'd never turn off my extraction fan.
    It's what pulls lovely CO2 into my tent.

    Also helps keep smell under control with
    my Carbon filter. Especially important
    during Flowering.

    Thanks guys. I been growing a while now & i have a intake fan fitted with a rhino carbon filter &the same for my exhaust. When its lights out i have my fans on a timer they come on every hour for 15 mins. Its fine but i just thought if it wasnt necessary i could miss out the very early hours. Fans do hum when alls silent. Its not noticed during day.

    Prolly not noticed here &im just overthinking lol

    I love it. Bit more hassle & thinking but certainly worth it.
    I dabbled with the fans cut down on when they come on. Bad move!
    All the leaves before lights came on were all covered in droplets of water.
    I have now got the fans 1/2 hr on 1/2hr off. &possibly just put them 24/7.
