Priceless!!! (Also had to do a double take to the OP just to make sure
)
We have one fan sucking air into the tent up through the filter and out to the outside. All of this is inside the top of the tent to reduce noise through the neighboring rooms of the house. We originally were going to have the filter and fan be outside the tent lined up near the outdoor vent, but the other design made more sense.
Here are some other ways a fan and filter can added to your grow tent.
One other note. As long as the fan and filter combo are large enough. You could connect the small veg tent with the larger flower tent. Then use any of the set-ups below on the flower tent to vent and filter the air from both tents out into atmosphere.
