You don’t need an exhaust fan. But you do need a fan for air movement. I use an exhaust for drying because just having a fan in my dry tent causes positive pressure and stinks up the place.

Not needed. I have a small filter on mine but it’s not needed. I put the vent up against my vent flap of another tent so air gets filtered and drawn through the dry box

I need an exhaust fan. I don’t know how others get by without, but I use one with a carbon filter.

So its the same concept as growing the plantwant good air flow an dark dry cool no to hot

Circulation v airflow. You want air moving around the drying plants but not flowing through the drying plants. At least thats my understanding. Im on my first dry so don’t take my words for it.

Good stuff yea mine r occupied

Me too lately, use my AC Infinity T6 and set the exhaust fan to keep RH at 60, makes for a nice slow dry - 7 days or so at 67-68F, about perfect and great for terpene preservation.

The vivosun 2-4 is great for drying one plant but with 4 plants shoot I had 2 tents used for drying n a box I made but my room smelled lovely n I think I’m doing this right with curing

Awesome! Just remember to dry slow at low temps. And like 60-65% rh 6-10 days should be your target.
Don’t forget to burp your container every day for 10mins for the first week and congrats on the harvesting! Oh and PICS and smoke report stat!

Hey there Bobby.
In your room do you leave your internal fan on all the time and then have the exhaust fan go on intermittently?
Or are they set up to turn on and off together?

Thanks.
