I'm very new to the forum and am building a 400w hps grow box from a clothes wardrobe about 4'x4'x6'. It is separated in the middle making two chambers and I was planning on moving it over to make flower side bigger. I just want to know if I could do a passive intake from the Veg chamber into the flower chamber or if I would need another fan.

I will veg under florescent or cfl so i dont think it would be too hot, if that helps!
