I'm going to have a tent that is 4'X2'X7'. I'm going to have a section divided that is 1'X2'X7' for a mother and young clones with some CFLs for light. Then I'm going to have the remaining 3'X2'X7' for vegging and blooming plants with a 430W HPS. I'd veg in the small area but I think its too small. Anyway, I need to vent both areas and I have one fan with one can filter. The two areas are going to separated by poly film. I was thinking of cutting a hole in the poly film the size of the filter and have half of the filter in each chamber. Would that even work? What do you suggest I do to vent both rooms through the same filter and same fan?
