You can use one fan for exhaust with a passive intake. (just a hole to allow fresh air in)
Then you will need an oscillating fan to blow on the plants to help stengthen them and to move the air around the room. You will need to make the passive intake light proof in the budding area. There are many different ways to do this. Good luck
