Blackout cover

[Sonnyhad]

Does anyone know of a blackout cover for the rectangular vents in the bottom of the grow tent, so light won't get in, but still be usable to help cool the tent?

My tenant has a rectangle and around opening so in the round I came out with 90 then a piece of flex to the top of the tent with a screen over it being held on with a rubber band. Then I went into the tent with the lights off to make sure no light is getting into the tent

yeah, but i need more intake air and those screened vents would be nice, but nothing to keep the light out!! I have the round vent hole filled with 6" duct.
