As a general rule, the air should be exchanged 3-5x per minute. So you need a fan that is rated and moves air @ a CFM (cubic feet per minute) that achieves this for your space. Keep in mind that the filter will introduce a load on the fan motor, and slow down air flow, so you want to account for this by choosing a sufficient CFM fan.

Can RH be raised to 100% for short periods of time?My extraction is noisy and the humidity is causing a sore throat at night. Can I switch it off and raise my RH to 95% on a regular basis without stressing the plants? I have an indoor grow 2"x2" that runs full ventilation. RH rises from 70% to 95% after 30 mins of no venting.

Circulation / Exhaust Getting ready to install carbon filter; found myself wondering if growers typically leave their filters/exhaust/fans on during dark periods? Up to this point, I've had everything on one power-strip/timer: circulation fan, exhaust fans, and lights. Should I keep anything on 24/7?

Do you think this is a better position for carbon filter so it can have better airflow or is it more important to scrub air from the top and have 2 90 degree bends? I'll probably try this in my next grow. Pic with drying plants is setup from before with 2 90 degree bends.

Cooling whilst using humidifier outside a small grow tent I have a small 90x90x60cm grow tent with a VIPARSPECTRA 300W LED. Heat levels are crazy and running a small humidifier with ice blocks inside the tent along side extraction isn’t cutting it. Could I buy a bigger humidifier, keep it outside the tent duct it in to keep it cool?
