what size inline fan for my indoor grow?

hey guys! i have one bedroom about the size of a small master bedroom or a big kids bedroom and in it I have one grow tent 4x4. I plan on adding up too three more 4x4 size tents total for a veg flower mother and clone room with the veg and flower being interchangeable, If I have the whole setup filled to the T with plants what size inline fan would I need. p.s I live in a shared house but I only have two neighboors one is cool one is probably cool too. I will be either stringing two together or just keep the fan inside a tent a nd carbon filter outside of the tent to scrub the whole room. silence is a huge priority im paying extra for it. I have my eyes on the ac infinty cloudline s6 because its the quietest for the size. can I scrub my whole room? "its a large room not huge" or should I "daisy chain" the stinky tents together? idk any advice I take now. very nice. or should I get two of the four inch ones and run them at lower speed in both of the 4x4 tents? budget is important but im willing to sacrifice. because passion cultivates excellence. thank you fellow stewards!

Get a bigger fan than you think you need and turn it down with a speed controller. It will be quieter than running a smaller fan with full power.

I have a 4x4 tent with both 4" and 6" ac infinity inline fans, I have a carbon filter on the 6" inline fan, the 4" fan would be fine for the 4x4 tent without the carbon filter, but with the filter get the 6" fan and it won't struggle or run on high, important if you want low noise.

I have two tents in one room, one veg and one flower, I have a 4" exhaust on the veg and 6" exhaust with filter on the flower tent. I also live in Vermont, so it gets cold this time of year. What I do for the winter is exhaust both tents into the room, and I then have separate exhaust fans that maintain the room temp and humidity by exhausting the room out the window as needed. I run the lights from 9 am to 9 pm, at night I run a Rinnai propane heater to keep up the room temperature, with the lights on the room can get hot and the window exhaust fans will cool it down. This way, I keep the heat from the lights in the room and don't need so much propane heat. You will need a pretty good dehumidifier to maintain proper humidity in the room.

Here you can see I have two (2) 4" ac infinity fans on one controller, they are both exhausting the room out the window thru the white hoses. In the front is the 6" fan I have exhausting the 4x4 tent, the other 4" fan for the other tent is not in the picture (4 inline fans total).

FYI, these 4" fans I use as intake fans for each tent during the summer, I run my lights at night and use these fans to bring cold air in to cool down the tents. I bought them planning to use them together like this in the winter, I really like ac infinity because they are so versatile, and the controllers are amazing.

So far, it is working perfectly. Maybe something like this would work well for you.

Edit to add: something else I did to make things easier, you are going to need lots of water. I added a hose faucet to my shower:

I use the faucet with a hose to fill a trash can in my room:

Now all the water and nutrients are right there next to the tent ready to go. No carrying, spilling, dripping, making a mess.

I hope this helps, good luck!

Do you leave the top off on the can to evaporate chlorine?

Yes, I do, but my town doesn't use chlorine, they now use chloramine which is a little different, I don't know if it evaporates the same. The big thing for me is letting the water get to room temperature so it doesn't shock the roots, and also I am disabled and cannot carry anything so this was a necessity for me. Thank you.
