I have no way of controling fan speed. These fans are not suited for a speed controler. I am afraid of having too much air flow. I have been thinking of ways to reduce air flow. Is too much air flow a bad thing?

I really ball parked the fans CFM. I reviewed paint booths that are a similar size. They move about the same amount of air.

And I do not have a drain. I will be pushing the water out with a broom.
Learn something from how turbochargers are designed. Too much airflow can be dealt with by ducting the intake for the fan and having a gate that either pulls air from inside, or from outside. (i.e. bypass the booth if you have too much airflow, then you can adjust how much bybass is used until you get the right airflow) Kind of like a waste gate in a turbocharger.
