The best inline is one you can buy locally, and has a 3+ year walk-in with broken fan, walk-out with new fan, warranty. Grow/Hydro stores should have this. Also industrial supply. If your inline breaks, you can't wait 3 days for a new one in the mail. Much less sending it away for warranty repair.

If you are in a situation where you need to mail order, Active Air has been solid for me. Three on timers and one on 24/7 duty, no failures in 2+ years. Don't buy anything that looks like this.

First, welcome to the enclosure club! You'll love the cost savings and lack of heat.

Here are a few points I'd like to make:

  1. Install fans at the top of the unit
  2. Ensure you have the proper air flow. Here is a document explaining how to calculate flow in enclosures.
  3. Space out your fans. Unlike the photo you posted, you don't want to necessarily just draw air out of one central point. This can cause hot spots and some cards may not be cooled as well as others.
  4. Leave headroom in the enclosure for hot air to collect. This may not seem important, but my cards get a LOT warmer when moved three feet closer to the top.

    You're looking for inline fans. I personally run Vivosun 440cfm units. I ran only one when I had three rigs in my tent, but after moving my ASICs in, I'm hooking up a second to improve temps a bit more.

    You can use conventional 6" dryer duct to move the air, but make sure you get the proper worm clamps and a Wye splitter (or better yet, two venting outlets for improved flow). The straighter the ducting, the better flow you will get.

    Here is an old video that I uploaded showing when I just had two rigs. This is how it looks now, and creates quite a bit more heat.

    Good luck with your build!

You again! Thanks for your help :)

I've also read that booster fans aren't great if carbon filters are involved and I'd rather have too much power than too little. I'm legally only allowed to grow 4 plants so I don't think my setup will ever expand beyond a 2'x4' tent, 3 plants at a time. Your 10x12 room is much larger than my small tent, so perhaps a booster is sufficient even with a filter?

​

It sounds like a 6" inch inline fan is almost overkill since I'll likely be running it on low full-time. I also use my grow-room as a small office so quiet is preferred.

​

I"m wondering if a 4" inline duct fan with a carbon filter is the way to go, or do you still recommend a 6" inline with the carbon filter, at low setting? I'm looking at this fan on Amazon. The total cost is $193CAD including filter/ducting. There's only $10 difference between 4" and 6" so 6" is likely better.

It's a hot mess at the moment and I don't have a good photo, but here are the pieces:

u/treefarmercharlie · 1 pointr/microgrowery

I just installed this Vivosun 440CFM fan from Amazon and it hasn't had any issues keeping the temp and humidity in line on my 48" x 48" x 80" that also has a 32" x 32" x 60" tent connected to it.

u/EnigmaGrows · 1 pointr/microgrowery

An intake fan will double as an outtake fan depending on the way you face it. You can use two intake fans and use one of them to suck the hot air inside the top of the tent and blow it out of the tent with another fan to pull air from outside and blow it into your tent or you can do it how I do it.

Most tents have velcro flaps that pull up with mesh screens on them to act as air vents. If you have your tent near a wall I open the flap close to the wall that way it is shaded so I don’t have worry about light leaking through it. Then I use one intake fan inside my tent and I duct it out of the tent and out my window. All other intakes are sealed but one or two air vents that are shaded from light.

This creates a negative pressure in your tent. The hot air has no where else to go but through your fan and out of the tent and then the air from the room your tent is in is being drawn in from your passive air vent.

Almost all tents have these vents located in multiple spots for this. Ideally you will only need to buy one fan for your tent.

EDIT: something like this and some 6in ducting with a few rope clip hangers from amazon and you’re all set

u/FluffyMuffy69 · 1 pointr/microgrowery

So, as is surely obvious, I'm completely new. I just set up my tent, which is 2x4x5'

I purchased a mars 600w LED, a charcoal filter and two of these fans

VIVOSUN 6 Inch 440 CFM Duct Inline Fan with Variable Speed Controller

I just opened one of the fans and it is ridiculously huge. The reason I chose that one was it seemed to fit the holes n my tent. Which is

vivosun tent

Is this total overkill? Will it work? Ack. I don't want to have to mess with an exchange unless necessary.

u/a2lolo · 1 pointr/microgrowery

Okay! Do you think something like this would do the trick?

Part of me wants to cheap out and get the 4inch version but I don't wanna try and save 10 bucks and end up with something that won't be able to get the job done.

u/Love2grow · 1 pointr/microgrowery

It comes down to a couple factors. Carbon filters require a certain CFM to scrub air properly, if you're not pulling enough air through the filter it can not scrub the air properly.

Outside of the filter not doing its job at a lower airflow, A bigger inline fan will pull enough air from a smaller tent (4x4 or smaller) that you can achieve a negative pressure that will regulate your RH, as it will basically suck up and out any condensation that has been expired from your plants.

u/user865865 · 1 pointr/microgrowery

This is what I have, but I think this might be a good option too. I've heard of the second brand before, just no experience with it or the built in controller.

u/Amish_Rabbi · 1 pointr/lasercutting

Canadian amazon link but I have this. https://www.amazon.ca/VIVOSUN-Inline-Ventilation-Variable-Controller/dp/B01CTM0JF2

I quite like it, but would go one size bigger if I had a static setup, mine I take in and out of the window so I kept the fan small, if it was all rigid then I would up size it.

It is very quiet, the fan on the laser is often louder than it and even when cutting MDF it pulls the smoke just fine

u/StockEmotion · 1 pointr/microgrowery

All I can tell you is - follow the universal truth - You get what you pay for. Of course there are a few exceptions, I've found great quality products for cheap, but those gems are far and few between right?

That being said, you are on the right track. After reading reviews I ended up going with this filter and then I got this fan and so far they've been great. The speed controller is a nice touch. When it comes to carbon filters, they are mostly all the same in terms of design, so if you go with a cheaper brand to save 10 bucks I really don't think you'll be hurting yourself or your set up, but things like fans, mechanical devices, i wouldn't cheap out on.
