Look cloud line A/C infinity. They are insane with performance and my is only a little loud, like less than my clip on fan, on the highest setting and I use the filter sleeve it came with so it’s pulling even harder. DIY will never fucking work man. Not 100% and definitely not noise free. How you gonna move the air? There somethings that you DIY but personal I wouldn’t for the filter.

they are not that expensive that the other kind people pointed out. Save your self the headache man.
Hard to say, typically you want fans that are more of a centrifugal fan blade (like those used in computer laptops rather than desktop PC), which can create higher static pressure. Personally I use this beast of a fan but its significantly strong than needed: [link]
AC Infinity CLOUDLINE S4, Quiet 4” Inline Duct Fan with Speed Controller - Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics [link]
I’m thinking about getting this fan. Would I need to buy two? One for intake and another for exhaust? And also would I need to purchase the ducting separately?
None of the parts are top quality but it's a decent value. The big problem is the 300 watt TSW2000 is not enough light for a 4x4 tent. It's the right size for a 3x3 tent which is nearly half the size (16 sq ft vs 9). To fill a 4x4 for flowering you'd want more like 500-600 watts of similar efficiency quantum board-style lights. Or if your budget isn't that high, step down to a 3x3 or 2x4 cause that can still yield a whole lot.
If you want to go with Mars Hydro I'd definitely suggest one of their better lights like the SP 3000 for a 2x4 tent or their new cheaper FC-E series like the FC-E 3000 for a 3x3.
Also I'd recommend an AC Infinity ventilation fan over some generic one that will be much louder, not be properly dimmable, and of dubious build quality. I have this one for my 2x4 cabinet and I can barely hear it in a dead quiet room when set at 50% which is still more airflow than necessary.
Sorry, I’m still learning myself but here’s a link from amazon where I purchased it from. I was watching YouTube videos and found a grower who suggested this brand and he even offered a promo code for amazon lol.
This is the one I got, it’s pretty quiet and it’s works fantastic
I have a cardboard box bigger than the printer where I put my printer in. That box has a duct that goes to an exhaust fan which goes outside through the window using another duct. Works just fine. Exhaust fan is this one
What's your cooling and/or airflow solution. I'm looking to put a 48u in a closet and I'm thinking of a vent up top with an inline duct fan.
My next question, can the fan be purchased without the controller? They are only available as a set on their website. Seems like they would offer the fan without the controller unit, if they are designed to run 2 fans with 1 controller
Maybe this is the fan without the digital controller?
Edit: Amazon link
Yes, 4" exhaust fan should do it. I would also leave the doors open during lights on so that the heat isn't all trapped in the closet. But that's just me. If noise is an issue I'd go with AC Infinity.
If it's not and cost is more your concern, something like this might be better for you.
I'd be more inclined to get two smaller fans rather than one big one, but that's only because I like to control every detail and I'd be treating each tent as its own environment even though they're right next to each other.
First of all, I would like to thank you for your time and all the knowledge and advices you are giving me!
I will get this, let me know if it's good !
Ima check your youtube channel, subcribe etc !
Yeah the 4" one on Amazon was £100± for the basic control one granted compared to the equipment it's nothing but was more than I was expecting
Been looking for inline fans to throw on that vent. Thought about building a box behind the ass end of the server rack to try and vent JUST the hot air coming out.
I was considering something like this, or potentially the next one up with the temperature sensor to automatically control the fan speed:
Wanted something quiet.
Between these two fans, which do you think i should use as an exhaust w my filter and which would be better as my intake? I'm leaning towards the AC Infinity Cloudnine S4 as my exhaust.
Thanks so much!
Do you think a 4 inch fan is big enough for my grow tent?

Some of the links are already in the thread. The other peices are described in the write ups so you can google them to get the best deals. The two most expensive peice were the AC Infinity fan. Here https://www.amazon.com/gp/product/B07JB292JC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and the HoH 3 disc fog maker here https://thehouseofhydro.com/collections/all-products/products/3-disc-mist-maker-with-float-and-spare-discs
AC Infinity I went with that one for my apartment grow. You'll also need a carbon filter and ducting. All three will be $159.97 usd.
Vivosun this one has the filter and fan but youll need to get the ducting.
If you're just trying it out then probably go the cheaper route but you'll probably get hooked on this hobby so go for the AC Infinity.
Thanks- very helpful. Any experience with AC infinity? Some quick research on Amazon seems to be one of the quieter options though a bit more expensive

Little expensive all at once but if you smoke regular then take a T-break to save it for the essentials for your grow. I know it sucks but your gonna end up spending soooo much more or quit growing because of all the ‘$20’ you throw to keep the grow alive. the only thing I didn’t go decent in quality on was the light and it’s still a good light just not very large. But will be great for my mother plant I’m starting next year. It just sucks to make those mistakes and I want to try to do my part in helping other do the same. I have seen plenty of people use those fans for intake just to get air flow but for a filter you need a strong RELIABLE filter. It’s like your light, you gone for 24 hours and Murphy’s law occurred your lil cd fan died cause of course it did, and now you spend a week mending your plant while scrambling to find another $20 to buy the same thing. Look up the definition of insanity and break the cycle!
Sorry for the rant pretty stoned and want to make sure people invest when it counts. Keep at it and don’t give up!
not really to be honest, most of thjose metal ones do fine, if you have extra cash go for a ac infinity
They have been on the market for awehile now though so there should be good imitation ones no from other brands like vivosun etc
Get a duct fan like this. Very quiet. Moves a lot of air. Can be mounted in the attic space. Vent to the return air duct or somewhere near it. And get a filter for that door vent. You can get a temp controller for this thing too or just get a smart outlet and temp sensor and set up a automation to turn off and on at x temp.

Or one of their self contained all in one door fans. They have tons of choices. [link]
Thanks for the warning. Instilled some skepticism in me regarding that fan, hah. I do agree that it's probably a better investment to buy something of higher quality, so I wouldn't have to buy it twice... and an inline fan and filter would be something I'd end up using for another project (grow tent) later down the road if I get the opportunity.
The AC Infinity inline fan and carbon filter seems like a much better investment.
Thanks for the advice. Much appreciated.
I was looking at this site:
That site recommends 15-20 air changes per hour for a smoking room. My room is 8x12x7’ high which is 672 cubic feet. 15x that is 10,080 cf/hour. Dividing that by 60 minutes gives me 168 cfm needed for 15 air changes per hour. The larger bath fans are 110 cfm so I was thinking to try one since it’s sort of close. I don’t have an attic etc in which to put any inline fans.
Since the shed is detached I don’t have the requirements you have to keep the smoke out of the rest of the house so I think it might be close enough.
EDIT: they have a smaller model which seems like it will be perfect for me and it’s actually cheaper than most bath fans
The duct fan that im using is this one on amazon.
I originally had used a smaller 4" duct fan that was rated for 100cfm but that wasnt strong enough to evacuate the fumes from my enclosure. Im pretty happy with this fan as its quiet and i can barely notice it running sitting next to the printer.
Im in a full enclosure that i built and my enclosure temps stay around 80 degrees F while printing with this fan running at max.
