more ventilation questions?

[TamyLove420]

Can I ventilate my room for just 12 hrs a day or does it need to be under 24hr ventilation?

Would you thrive just breathing fresh air during the hours you are awake, and not when you sleep?

Well, I don't run the fans during dark. After 30 years, I see no difference.

I think that depends on how big a room you have, and the conditions outside.
If you had a small cabinet and its more or less sealed..... if you're running hydroponics your humidity will jump to the point you may be inviting powdery mildew and other kinds of disasters. Even if the humidity is high coming into your cabinet, ventilation will be better than just having the plants sit there cooking or sweating.

my room is about 12x4x8 and i created a nice ventilation...i think i figured it out.

22"x14" in upper 3 feet
on intake side its 22"x12" in the bottom 3 feet
both vents are a 3 part lifetime filter
fans on both intake and exhaust

do u think that is sufficient?

You're gonna want a fan over the tops of the plants and under the light.. Then, if the temperature in your room get too hot after the light has been on for a while, it's time to bring in a another fan or two. One at the intake, and another at the exhaust.... From there on its just whatever you have to do to keep the temperatures where you need/want them. The ideal time for lights on is 75F... and ideally you don't want the night to be any more than 10 degrees lower.
