Yes, you will need a fan that has sufficient ability to overcome the static pressure present in your design.
It’s often suggested to remove the total volume of air in a grow space at minimum at least once every three minutes up to more than 3 times per minute. If you take the area of your space to find the cubic feet you can compare with the CFM (cubic feet per minute) rating on a given fan. Not all CFM measurements on fans are created equal thought because the static pressure is important to consider.
For example, two fans might both say they’re rated for 300 CFM but that could just be at 0 static pressure (very little resistance for the air to flow) and when static pressure is increased their efficiency becomes noticably different with one underperforming and the other performing as needed.
Things that contribute to static pressure are things that reduce airflow and make it harder to move. This includes but is not limited to the length of a given ducting run, obstructions of a straight line, and screens or filters that reduce airflow.
If you don’t mind me asking, how big is your space and what size lamps are you running? What are your ambient temperatures and how much hotter does it get in your garden space?
Some run their lamps at night to take advantage of the cooler temperatures compared to running them during the day, something to consider if you haven’t already. Much love
