Its controllable.
You must understand that some pot is horrible in flower. Stay away from cheese, skunk, indica heavy. They tend to be foul smelling.
Sativa's will be more fruity. I've had some smell like caramel and coffee.
When it comes time to chop and trim you will need to build a make shift air lock, like a tent connected to the door of your tent to work in or you will need a second scrubber in the room outside the tent.
Mountain air makes just about the best filter on the market.
Good luck.
