Hoping everything works out for you! Oscillating fans really helped me out. I purchased three Honeywell oscillating fans from Amazon and they should do the trick for years.
I just recently washed my carbon filter sleeve. I let it run for a few days without one and the exhaust is so loud. The sleeve collects dust and dampens vibrations I suppose
For the longest time I’ve had a stationary fan on setting 2 that is pinned between the wall behind my tent and the tent’s screen vent on the lower back side of the tent. Helps push air extremely well from the lower canopy. But clearly not ideal.
With 4 plants in there at once it was too crowded. Not doing that again
