Growing autoflowers

So I’m growing my first plant (autoflower) in a 2x2 tent with LED.
It is currently on day 5 of vegetation and it has sprouted its first few leaves.

At this point, am I too keep the exhaust fan, oscillating fan and light on 24/7?
I’m aware the fans are to stay on 24/7 during flowering period.
I’m also waiting for a timer to be delivered then will put light on 18/6 schedule.

Also, can the exhaust fan direct air back into the room or does it have to be put a window/different space?
I’m not using an in-line fan, just the vents at the bottom

You can leave it on 24/7, I run 16/8 on veg. Easier on power bill. Veg area only has oscil fan and led. You'll want a inline fan with a carbon scrubber once in flower. Otherwise your whole house will reek of ganja big time. When my inline is off company can smell it no prob, but I cant, even if I'm gone all day I cant smell it so its extremely difficult to determine scent levels for me. The way I have mine set up is the fan draws air thru the scrubber, thru fan, ducted to my hps for cooling, ducted out of light to the top exit port hole on tent back into the room since hot air rises. Fresh cool air is drawn in from bottom of tent where I have a duct leading to a cardboard box where my digi ballast is to reduce sound from the tiny jet like computer fan as well as keep the ballast super cool, ballast doesnt affect tent temps 78° ac on, 82-85 ac off, 100° exhaust temp. Since you run led you can run a variant of this and itll be fine. There is many ways to route it. My flower room gets warm unless my central air is turned on. The entire setup can be as complex or as simple as you like as long as a few must haves are taken care of. I can upload pix if you like, any questions lemme know. I was in your spot back in december/January

I'd like to vent exhaust outside, but unless I cut a hole in my floor it's not viable to me as venting from a window might raise questions with my neighbors.
