Light thru a hepa filter

[doBpop]

Hi and thanks in advance for the help!

ebb and flow - 4'x4' 60gal res - 6"x6" square containers filled with hydroton
25th day into 12/12 7p-7a - girls around 3' tall
1000w HPS

I am drawing air through the wall from an adjoining room and have a 6" hepa filter on the other side of the opening.

Would any amount of light coming through this be significant during the 12/12 dark periods?

I can't 'see' any light coming through it from the grow room.

Thanks everyone!

If you're running genetics that are prone to hermaphrodism, and sufficient light is able to get through (or just about any other stressor, if they're prone they're prone, end of story), then yes, it would be an issue.

Thanks Seamaiden - I appreciate your kind help!

Here's a pic I should have included in the OP.

That's a 4" to 6" adapter sitting on the floor and the filter is mounted with a 6" collar flange.

Heh, that looks like our Excursion's K&N filter.

Yeah I know right LOL!
That's the same thing we said when we saw it.
