Way to Detect Light/ Light Leak Problems?

Hello, first time grower here. Here's the problem I'm running into. The fan I got pumps air a little too fast for my 5x5x7 grow tent. If I close all the entry and exit sleeves the fan will actually make a slight vacuum in the tent. In order to alleviate this I have to have airflow into the grow tent. I was looking around and I think the best method of doing this is going to be to use some tubing and make an s-curve tube which would allow airflow in and keep light out.

Because of this whole setup I am concerned that I may have a small amount of light leakage. It's nothing that's perceivable with the human eye, but I hear even small amounts of light leak during the dark cycle can turn my plants hermaphrodite. Is there any way of easily measuring how much light is leaking into the tent? Also, how much light is okay and won't turn my plants into hermaphrodites?

Any help is always greatly appreciated. :)
