DIY Exhaust 2 Tents with 1 Fan / Filter

We added another grow space to our garden so we need to exhaust it! Rather then buying another fan and filter we thought why not make some sort of "filter bucket" that can pick up 2 tents. This is what we came up with! Works perfect as both of our tents are similar sizes (44/40 Cubic ft).

Since I am using a 4" Fan, I drilled a 4" hole on both the top and bottom of the 5 gallon bucket. 

Installed a 4" tee onto the bottom side of the bucket to allow me to connect both tents exhaust pipes. 

Fitted the 4" Charcoal filter to the bucket lid (Easy to remove for cleaning / replacing)

Hung and Attached my Vivosun 4" Inline Fan to the "Filter bucket"

Finally connected the two Tents up, and piped the outlet of the fan outside the building.
