Into my pad.
I have two tents:
A veg tent 3x2x3 and a flower tent 3x3x6
The flower tent uses 3 passive intakes. Two from the top (ducting with pantyhose over the ends for air filter) and one that vents the veg tent.
I have a cool tube that exits the tent, goes through the fan and is pushed through a CAN 66 filter. The thing is gold. Zero odours. Lots of negative pressure in the tents.
I can dry in my veg tent as well because it’s vented.
My biggest issue is keeping my environment close enough to optimum conditions especially lack of humidity in the winter.
