does any one do this? do you keep a window open or do you take fresh are into your grow area from out side?

I do it, i take air from in the kitchen through some ducting that dangles over my stairs, when i have visitors i just chuck the ducting back in the room and open the window.

I also do it, I have taken a couple of bricks out of the unused chimney and put tights over the ends of the ducting. one for my air cooled light one for fresh air
