Help with my growBox

I currently have a grow box in my garage 5 feet High 4 feet wide it 'made out of wood. I need help with choosing a fan that will keep my humidity down by taking out old hot air. Also need a fan for bringing in air. I will need to cut out a hole the size of the fan to mount. I will not be using ducting.. I have been told to get a computer fan but I believe it's too small plus no 120 volt plug. I was looking to get Eco plus brand axial fan. Any suggestions would help thank you for your time.

cut a hole low and place any small clip type fan pulling in air. You can do the same for heat release up high. also a nice 12 inch or so fan blowing air around. I always put screens over my holes to help keep the critters out
