Creating small veg room within flower room - Ventilation Question

[gualapa]

I have n 11x10x10 flower room that I will be using for a vert donut grow. I'm going section off a 5x3 space in a corner with panda film to create a mini veg room to keep a couple bonsai mother (mini mother plants).

The main room has a passive intake/exhaust fan. for this mini veg room using fake walls (panda film), should I go with a intake fan/passive exhaust or passive intake/exhaust fan? I was told it'd be a good idea to go with intake fan/passive exhaust but I don't know exactly why it would be better than passive intake/exhaust fan.

I don't think it'll be a big deal either way. Blowers suck better than blow so I usually go with exhaust fan. Remember this room is going to be around ten degrees warmer than your flower.

Ok. I think I'm gonna go even smaller and just make a 3x2x3 grow box out of wood.

3*3*2= 18 cf. In order to get 1 air per every 5 minutes, I'd have to go with at least 5 cfm fan. I'm guessing some sort of mini computer fan would do it? I've been checking amazong, they have fans that are 20-35 cfm. Since my growbox will be in my main flowering room, I might as well just steal a tiny bit of air from the main room, right? Thing is my growbox will be on the opposite side of the room from the passive intake and main plants, so maybe it'd be best to have a 20 cfm fan to suck air from where it's positioned. I could always use thin piece of wood or something as a damper next to the exhaust fan to slow her down.

Yeah, just buy a cheap pc fan, or simply harvest one from an old computer. It's easy to power up, either connect it with an usb cable or an old cellphone charger
