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
