First grow advice

[The Hemp Goddess]

You are not going to be able to connect a filter to one side of the venting and not the other. The fan will absolutely pull far more from the veg room and you will have almost nothing going through the filter. When running a wye, you are going to have to keep each side almost identical in length and bends to keep air flow even--you need things to be balanced. Even having more ducting and more turns on one side will greatly affect the air flow. I really think you are going to need 2 fans.

Yeah that was my worries, I was hoping that it would have worked temporarily till I could get another fan I'll just save up for another fan, Would I be able to put both exhausts into a wye like a 6"x6"x8" so I dont need to have two holes in my roof; unless I can vent out of the ridge cap?

Edit: Could I also dry my buds in the flower room to keep the smell down during drying?
