Good solution for extra fresh air, also good for eliminating excess moisture

Works great. Only need to run fan on low setting to push or pull air. Fan is very quiet on the lower settings.

This is a simple and small fan, which makes a big difference in providing more outside air to the grow tent - helping with mushroom growth. I highly recommend that this be added as the mushroom yield will likely increase.

This was just the trick to improve the air exchange in my tent and improve my growing.

Great add on, very universal and customizable. I would pick up an extra timer to run this but otherwise its very clever and simple solution to moving fresh air, if you need to!
