As I am going to use just a couple of cfl's in my veg room I think its safe to assume it wont get mega hot in there so instead of having separate ventilation in there I intend to use a bigger than necessary fan in my flower room and vent the veg room into the flower room and out.

Firsty I am assuming there is no problem with this, if anyone thinks so then please say.

Secondly, and most importantly has anyone got any suggestions how I may do this through a black and white partition without leaking light?

Thanks for any guidance

Any thoughts guys? is this a stupid idea? Do I need seperate vent in each comparment?

I'd really appreciate any guidance here thanx

I personally dont see an issue. Use black cloth stretched over both sides of the fan. Air will flow through but particles and light should stay seperated.

sacrifice a pair of dress socks and you should be good to go.

Thanks muchly

Do yourself a favor however when you get the cloth fit over it turn on your flowering light and look for leaks. I think the most you may see is a few speckles dont know if thats too much of an issue.

you might want to try that white plastic that is black on one side. i don't remember the name of it, but i've lined my walls with it. It's pretty tough to, I have it seperating my bloom and clone space
