Okay, I'm going to go with an EBB & FLOW in my flower space. Should be nice. Anyway, for the ventilation setup I'm a little stumped. Check out my attached diagram. I *think* this is the way I should do it but I'd love some input. I have to use the 4" bathroom exhaust fan space (the bathroom exhaust to the roof will be connected to the exhaust for the room) as a passive intake inlet (I could add a fan here if necessary) because I can't cut the door to the room to add a vent and there are cabinets on both sides of the door so thats a no go as well. So my questions are: 1. Will the passive intake be sufficient this way? Should I add a fan? (I made a misake in my diagram, its really only 4") 2. If you look at the diagram, I have the ducting going THROUGH the flower room and leaving a passive intake hole here (T connector) and then going out to the rest of the closet and finishing off the intake inlet. Is this ok? 3. The exhaust is also set to exhaust both the flower room and have a smaller exhaust for the rest of the room (to grab any exhaust from the cabinet where the moms will be). The flower room is pretty much going to be sealed with mylar so that I don't have any light leaks. My main concern here is negative airflow / vacuums... this is why I hope the passive intake is sufficient being that it is going to be split into a sealed flower room as well as the rest of the room. The exhaust is going to be doing the same thing. Maybe I'm over doing this, but the space has to be shared and since the flower room can't have light leaks I figured this was the only way. Let me know! Someone!
the exhaust fan itself should work. I'd try it, if its still hot then i'd add a intake fan. But that fan should pull the air through.
