Air Flow During Veg

I haven't setup my garden yet, but I'm already worried about vegging in the closet. I'll be using 4ft 4 bulb T5 HO LED's on 8-9 plants. Given the LED's fit (haven't gotten exact measurements) would I be ok with a basic clip on fan in the closet? Will I have to open the door up at times?

I have a 4" carbon filter w/ fan, 600w HPS & a 78x78x78 mylar tent for flowering.

Oh BTW the closet's height is about 8'. If I had to guess I would say it's
4'x4'x8'.

Yeah no problem but t5 lights and led aren't the same. Not sure about led, dint trust it but a t5 should be fine plus I like a higher temp for veg, more light intake and no powdery mildew problems. Better yet u can get a old door of cl or homedepot and cut an exhaust hole in it

Heh yeah they're t5's, blame it on information overload I'm trying to throw all these new terms out there . Do you think I'll be fine with no exhaust hole? If not that's a great idea to incorporate one considering I live in an apartment haha.

I like the idea to buy a cheap door from home depot. ty

I definitely think some ventilation would be a good thing
