Exausting outside of grow room

Setting up two more tents. There will be a 2.5x5, a 2x4 and 2x2 for flower. The 2.5x5 is on other side of room with 6” S line vortex inline fan. It right now is making negative air pressure in the room.

A 1x1’ caninet for mothers is next to that which may or may not need to be connected to reduce heat in the room and inside tents.

Though the other tents are on the other side of room and probably need their own fan to travel to window where they can all meet to vent outside.

The tents on other room are the flower I mentioned but also a 3x3 veg tent that runs hot. So that side of room is a wall of tents wall to wall. 3x3, 2x2 and 2x4.

Theyll all need carbon filters but how many fans? How many can one 6” S line vortex handle if I wanted to chain them? My search shows easily 2 but what about 3?

Thats the rest of the setup, just figured out the drip system. Floraflex works great.

Connecting your tents ass-to-mouth is less than ideal but ultimately your environment will dictate how well it works.

lmao a cannapede. Cannabis sentipede what ever you know. But I saw pics of a two tents, filter in each that meet at the top of tent to suck passed the fan into one line out the window.

They all have to vent out the window with smell control or the room and tents heat up too much. Rh builds up too.

Why don't you take a look at infinity 8 inch inline? I run an infinity 8 inch going to a passive roof vent in my 5x5. I realize it is waaaaay over kill, but I only run on setting 2 of 10. It is flippin quite at that setting. It cools off 2 spiderfarmer sf4000's with drivers in the tent. People always complain about how much heat is put out from them and end up moving them out of the tent. Just a thought but it might make your situation doable.

So just one tent for the fan you have? Just making sure I understand. I was considering ac for their quietness but am a sucker for reliability which vortex almost guarentees 10 years based on warranty while others are 1-5.

I would consider it if you think itl work, I have enough noise in the room and could use a quieter setup. I know you lose some power in exchange for less noise with ac fans thats another thing.

Yes my set up is very much overkill but I don't want an air set up that has to run on the highest setting because you know it will be very I can hear it on the other side of the house loud. Also I feel the less work the fan has to do the longer it will last. Don't know they cost n I w but mine was 280.00 the 25 foot 8 inch ducting was like 35.00. Uf I put my 8 inch on high in my 5x5 and sealed it up, might just crush the supports. The ac infinity 8 in I believe is rated at like 810 cfpm.

Ok thats cool though a 5x5 is pretty big. Il look into it. I just wasnt sure if my idea would work out of if I need a fan for each tent. If I could at least bind them into one duct that blows right out the window was my next question if all need separate fans.

One might need less are than the other?

Does anyone know Pascals? Thats the ac infinity pressure rating for 8”, 746PA. It says equal to 38 mmh20 but forget what that would mean for the CFM in 1mmh20. For example the S -800 vortex is 570CFM under 1” h20.

Whats the ac infinity? Is pascal a good rating to find out? Heres the data from vortex that I must see before buying a fan.

Is this good to add 4” filter on each and adapt it to 8”? My 6” in 2.5x5’ tent is barely enough on max flow so this would be 21 sqaure foot vs 12.5 but are the duct fittings ok, will this work you think?

That looks pretty restrictive. If it was bigger, maybe..

Just save yourself some money, and buy a plastic storage tote, and cut holes in it to make whatever size ports you need. Get the good kid of bin that has a seal in the lid. Use it like a duct junction box

And make one 8” port straight to the fan? What about the backend, should you just keep it 8” and vent straight outside or can you reduce it to 6” and joint it to a coupler that another 6” fan exausts out of?

Are you trying to hook 3 carbon filters to one fan, or hook 3 tents to one fan?

Both, 3 tents with 3 four inch carbon filters need ventilating and odor control amd vent outside for heat control and rh helps alot.

A 3x3, 2x2 and 2x4 with filter in each, to one fan that vents to outside .

You could fill it with charcoal and have one charcoal filter for the room too. Damn it now I want to try that. You'd also have to size your blower and ducting to fit the combined volume too.

Could also cut up a section of carbon infused filter padding, to use like a screen for extra protection so you don't blow or suck pieces into the fan..

It would probably be best to hook the fan directly to the tub\bucket. Flanges to hook up ducting could easily be made by taking a 1-2" wide strip of thin plastic, and wrapping it around inside the holes, then using epoxy or whatever to glue it in place.

Another way I was thinking was a couple of these if I can find them cheaper. It will make 3 ports. Shoot, I was almost sure I could figure it out with one 8” fan and already bought the fan.

Before making things worse I can return it and buy separate fans for each tent if thats better.

Should probably give it itsown vent 8” exaust instead of reducing it to make it work and joining them to one exaust port.

Thing is a monster. Loud too. Idk if this will work, shoot lol. Might need to return it and get 3 ac infinitys.

Damn, I tend to do that to myself but whatever. Im returning and getting 3 ac infinity and figure out how to exaust all them into one duct, that can work right?

The 4” ones are 28dba I think I can live with that. Allows control for each tent given I figure out how to exaust them however way. Should of just done that.

The ac infinity bearings rated for 7 years and just ought to give them a try. It should be pretty damn quiet.

My 6” vortex on highest setting isnt even loud. I cant find dba ratings on each setting and just overlooked again.

This is louder than my dehuey 500w. If to guess this starts at like 45dba, dehuey rated 35 at loudest I think.

Edit The 6” fan is 50dba and so is the dehuey. Weird because the fan is quieter. Does connecting ducts reduce it to where I should try connecting it and see if its quieter?

I feel like it wont work because you can just hear the motor its self, if the dehuey is 50dba then this must start at like 60 but tops at close to 80 per search.

Shoot that means the ac fans are rediculously quiet and am going to just get those.

My ac infinity 8 inch inline is the whip. Running on a #2 setting even in the room you really can't hear it.
