Howdy folks!
I attached a rough sketch of the growspace.
Measuring in centimeters (cm):
D = drying chamber (about 160 height, 90 wide, 90 long)
Veg = veg chamber (about 180 height, declining to 165. 120 wide, 150 long)
F1 = small flower (about 180 height, declining to 165. 90 wide, 110 long)
F2 = big flower (about 205 height, 120 wide, 140 long)
I marked the room's intake and where the exhausts should go in the sketch. Each chamber will have its own passive intake and active exhaust.
Toward that goal I have in my posession:
- 3 centrifugal blowers rated somewhere between 300 and 450 m³ and 100 and 120 mm diameter ducting
- 1 tube axial fan (no clue about the rating)
The Tube axial fan I wanted to use for the drying chamber (D).
The two best looking centrifugal blowers I wanted to use for Veg and F1 (small flower).
I have my doubts that a 450m³ centrifugal blower is enough for F2 (big flower) and wanted to buy a 750m³ one for that job but obviously would be happy if you guys say the 450m³ is enough.
The 750m³ blower would also be using 200mm diameter ducting so adaptors would be required...
Now comes the real question:
If I put a fan+filter combo into each chamber, how do I get them all to go out the one exit hole in the wall?
I was thinking I either use Y or T connectors to reduce them all down to a single 200mm duct that I connect to the exhaust hole in the wall.
Or a lung-chamber/lung-box in front of the exhaust hole and connect all the chamber exhausts to that lung-box.
But then I need to have a strong (maybe the 750m³ one?) blower between the lung box and exhaust hole, don't I?
Your advice is highly appreciated!
Also:
I haven't given any consideration to the size of both the room's main passive intake nor the chamber's individual passive intakes...
For the exhaust hole I planned to just make it 200mm diameter to be compatible with the largest size ducting I may use.
My whole approach seems a bit iffy to me and I am not entirely confident I am doing it right. But I am also at a point where I did so much research and am on the cusp of starting and I don't know if I can muster the strength to become a ventilation expert as well...
I think I will get going next week no matter what. Just hope my layman's approach will not leave me with long-term problems..

Forgot to mention:
Veg = 400w MH
F1 = 315w CDM
F2 = 315w CDM
