Are passive vent flaps a potential light leak?

Trying to make sense of this? I've just bought a mini grow tent set up due to space it's a vivosun 24"×24"×60" but I just noticed there's no f#£@ing intake port holes? For an intake fan It only has passive vent flaps but how will that not cause a light leak during flip if the vent flaps are open?

I dont get any issues from light leaks. I roll the duct ports wide open. Negative pressure with no intake fan. It takes a lot of light to bother them and be able to photosynthisize. Its good for extra airflow to keep rh in check. Herms will herm, Im yet again changing my setup to have nothing but single plant tents. So they cant pollunate eachother or contaminate as bad with mold if I get it.

A true female wont herm and is breedable if you want to. A good clone with a low tendency to herm is still good for repeatable results. No need to worry about the age old light leak concern which Ive found in my journey of studying breeding. If it herms and seeds you can still cure it, then dry it brittle and run through a sieve and de-seed a pound real quick.

"Surprise!" - yeh, that's both a head scratcher and a pain in the ass.

My thinking is that the answer is "perhaps" depending on the amount of light in the room in which the tent is located and the direction of the light.

You might want to contact their customer service people or you can use a set of these.

Good idea bro But the vent flaps are rectangular not circular unless I'm misunderstanding something? Here?
