Exhaust always necessary, intake for a small amount of plants is enough just opening the door daily...

If door open than Intake. Becouse the breeze will move plants and they will become stronger. Thicker main steam

High humidity temporarily
For a few hours yesterday the humidity in my grow space went up to 90%! Should i be on the lookout for any issues? The fan in the tent came loose from the pipe. Thankfully nothing was damaged. Fixed it afterwards.

Utilizar filtro de carbono sin manga??
Can I use my carbon filter without the sleeve it comes with?? It's just that when I put it on, I lose power in the extractor and the negative pressure isn't generated since the duct from the extractor is bent??

Connecting 2 grow tents
I have a 16"x16" small tent next to a 48"x24"x72" tent. With 1 small plant in the small tent, is there anything wrong with ducting the air from the small tent to the bigger tent where my carbon filter is. Seperate intake and exhaust for each tent. Has anyone tried this before?

Ventilation Setup for Smell Attenuation
Is this setup ok? Since the air tent will be recirculating i think the smell will be atenuated. I haven't seen other growers with this setup (I'm a newbie though), so I wonder if there's something wrong with it.

In-line fan use
I’m just wondering how much to run an in-line fan. I’ve read every 1-3 mins, but I would like to know how long does it run in between those times? Is it constantly turning on and off? Do I need to put it on a timer? Thanks.
