Question about air filtration systems
wjkingsnorthstarted grow question 2 years ago
I have a question about Vivosun Air Filtration Kit for grow tents. I am not using the air filtration system in my current tent. I have noticed the humidity and temps are much easier to control without the filter. Has anyone else experienced raised temps and humdity using a filter

If the filter is affecting your results your fan is too small, or the filter has too much resistance. I sized my fans so they operate normally at 30-50% of capacity. This helps keep them whisper quiet and leaves plenty of head room for emergencies if you need to crank it up.

Air filters will restrict the airflow your fan is doing. So if you have a fan set on 3 and you put an air filter on you would have to raise it to a 5 or more to compensate for the restricted airflow.

More air movement and quicker air exchange makes it easier to keep cooler but the fan is louder

Ventilation set upI just got my first grow tent- a Vivosun 32x32x64 and a Vivosun 4” fan and carbon filter combo. It came with directions for the tent- but nothing on the ventilation system. What’s best as far as set up? Any tips, recommendations, or photos.? Does it need to vent outside?Setup. Ventilation

Won't Oscillate AnymoreI was wondering what type of oscillating fans that everyone uses in small grow tents. I have been using the Vivosun fans and since they won't last I'm looking for alternatives. In case it matters I'm growing in a 27x27x63 MarsHydro tent.

Low humidity issueTents 20'' × 30''. Using a vivosun 6'' inline fan to exhaust with passive intake to create negative pressure. I have a good humidifier but even on full the rh doesnt go above 40%. Not unless the room the tent vents into becomes super humid as well.
