Can I use my exhaust air to ventilate my vegging room?

I have a 4x8 flower tent and a 4x4 veg tent. I don't want to buy 2 more fans for a small veg room so I was wondering if I can exhaust the air into my veg tent and just let it leave from there passively. The intake fan in the flower tent is fresh air from outside if that changes anything. I want to do it this way because i only have 1 vent in my garage to get new air from and i want to be as efficient as i can. Basically im wondering if exhaust air can harm me newly vegging clones? I cant imagine this can be too much of a problem considering a lot of people just grow in closets with oscillating fans. Just trying to get some input on this because its kinda hard to search for something this specific on google. thanks in advance

Unless your flowering room is filled with spider mites and mold spores, you'll be fine.
