Light proof air vents?

Hi peeps,

Need some more help if you don't mind.

I need to get my Snow White flowering asap, she is almost 1month now.

I have 3No air vents in my box, 1No in and 2No out. My question is... How do i make these vents light proof?. They are roughly 90mm x 90mm.

See pictures below.

thanks for the help!

is there anyway to add some tubing onto the outside and point it towards the floor? Also got enough room to build a bottom opened cover for the vent? (basically a small box over the vent that has an opening in the bottom so light can't get in)

i do have some 4" tubing from my tumble dyrer but it is only thin white plastic although i reckon i could run black tape around it, I was thinking about the little open bottom box to cover the fan but thought that would still let light in.

Anyway im going to go with the 4" tubing now, so i should be flowering very soon.

Thanks for the help EpyxN
