I leave it on all the time as well. Plants do good with fresh Co2.

Yeah, I leave mine on 24/7 as well. Also, if smell is a concern, once they start to stink you'll really need to keep it going to keep the air flowing through a filter(if you have one)

Yes. Learn how to hang it from something that will absorb vibration like rubber grommets or bungies.

Leave it on 24/7 unless you're getting too much of a temp drop during lights off (I really doubt that little guy could do that though). Fresh air is always good.

Exhaust 24/7. Fresh air, even during the dark is good.. unless you have severe temp or humidity issues. I turn my internal stem-shaking canopy-cooling fan off with the lights though.
