Suggestions on 6" or 8" Cloudline for 4'x'8' tent

Currently waiting on my 4x8 tent to get shipped and arrive. Lights just arrived today. Going to be a flower tent, with 2 different timed crops inside. Going to get a Cloudline fan, but not sure if the T6 will suffice, or I should just opt for the larger T8 that says it can move twice the amount of air. Hoping to get some opinions on this.

I have a t6 in a 4x8 and it’s plenty for the +\- 900w of quantum boards I got in there. If running hid lights I’d go for the 8”

Get the 8 you may never know. Plus it has a control seting on it so you can control the speed.
I'm copying my post from another thread on fans:

I will give you a nickel's worth of free advice here that will increase your production, solve your heat issues, and do it affordably with quality equipment backed by a better manufacturer's warranty than the cloud line fans. Let's do this. Cloud line fans are warrantied for 2 years. They warranty them for 2 years, because that is their expected life. They have a relatively high failure rate, and they are attempting to do too many things with the product at too low of a cost to engineer it to last. Solution? Get an inline fan from a manufacturer that has a better warranty. Get an inline fan that is only moving air. No environmental controllers or other cheap bells and whistles that do not contribute to moving the air.

Recommended inline fans:

#1) Vortex 6" Power Fan manufactured in Canada $114.99 backed by a 10 year warranty. These are what professionals use in the HVAC industry. I have one in service cooling two 1000 watt HPS lamps that runs quiet and moves a lot of air. No issues in service for over 3 years. Great fan highly recommended.

#2) Soler and Palau TD-150 $122.99 with free shipping backed by a 7 year warranty. I'm unaware of the country of manufacture. These are what professionals use in the HVAC industry. They are built to last. I have a td-125 I use for my veg tent that is 12 years old and still running like the day I first fired it up. Clean every 6 months. I also have a TD-150 that will be installed on a new tent I'm setting up next month for mother plants. You have to hookup your own power cord and wire clamp to these which requires about 5 minutes time to do the job and another 5 minutes of your time to watch the youtube video on how to install the wire. Fantastic inline fan for the money. These are the quietest fans on the market. Can fan takes a close second for quiet operation.

#3) Can-Fan Max-Fan Manufactured in Germany $174.99 with free shipping backed with a 5 year warranty. Can-Fan is the industry leader in filtration and inline fan technology. This unit comes with an integrated 3 speed fan controller. I have had one in service for over 8 years without issue. They are pricey, because they are specifically marketed to the cannabis industry. Everything marketed to the cannabis industry is more expensive than it actually should be. They're great fans, but I would never pay $174.99 for an inline fan that's worth $135 at most. Speed controllers are $10 on amazon. You could buy a Vortex 6" Power Fan for $114.99 and a $10 speed controller for a total investment of $125, and you have a fan with a better warranty for $50 cheaper. It's your money though. Spend it as you see fit. I got my max fan used for thirty or forty bucks from another grower a long time ago.

For fuck's sake do not buy one of those shitty cloud line fans. You will never see one of those crummy devices in a professional grow room. Pro's cannot afford equipment failures. We use quality gear with low failure rates backed by lengthy extended warranties, so if something does go wrong it's replaced at no cost to us. One last thing, word to your mother!

For me, every 4 x 4ft space, needs at a minimum (1) 6" carbon filter (with a flow rate rated at 240cf or greater), hooked to (1) exhaust fan (with a flow rate rated at 280cf or greater) combo. The math... for my example is... 4 x 4 x 7ft space has a total area of 112csf x2 = 224 total csf. The (x2) relates to the exchange rate, you need the exchange rate to be at least (x2) of the total cubic feet that need to be exhausted. Why the (x2)... because using just a (x1) flow rate won't effectively contribute to lessening the heat that will be generated by your lights. A (x1) flow rate moving across a heated surface provides less than a (2%) thermal heat reduction at the source. But a (x2) flow rate moving across that same heated surface will provide a (18%) thermal heat reduction at the source.

I bought a T6 on sale cheap as I was trying to plan my room to be as silent as possible.

When I couldn't keep the room in the right temp range with it alone (I knew it would be borderline for the CFM rating but was space limited), I cut the additional holes, and added a regular vortex fan to air-cool my lights. The T6 now *just* does the job on almost full out.

Also, it turns out with both fans running, I still can't hear anything outside the room, so the noise level was never going to be an issue (premature optimization). Given this knowledge, I would never buy a cloudline again as the bells and whistles it comes with aren't that useful or exciting in grow situations. I had mistakenly thought I could use some of the features as a poor man's environment controller, nope.

I think AC Infinity saw an opportunity to re-market their audio cooling line to growers but has done none of the work to tune their product into an entry-level semi-usable grow room/tent fan.

For me, it is on full out, all features off all the time, but at least it has a nice temp/humidity read out that seems rather accurate. Does anyone else here find any of the features to be practically useful in any situation? If there aren't any arguments showing good use-cases for the built in features, I would save the money.

I use the high humidity and high temp set points. At first I thought I would have an issue with the fan not running . It turns out when the fan shuts off, the humidity rises and then the fan kicks right back on.
the high heat I set to 80 and high humidity I set to 60. I might turn it up to 65 for veg though.

If I had heating cooling humidification and dehumidification, I would use all the set points
The point of the fan ramping up and down is to kind of cheat a little to rise temp and humidity. The alarm set points will bypass the fan speed setting and ramp the fan up to maximum speed. I am running a 6” on speed 7 in my 5x5

also the fan ramping on and off and up and down saves a lot of money in power

@Nizza Those are valid use cases and is definitely one way to make it work.

To me it is truly missing a min-speed (instead of just off off) and a set point that then ramps up to a user definable max (or just max speed).

It does have this sort of, but it is considered an alarm state, and comes with an annoying beep (open it, and detach the buzzer?).

I experimented with this for a while, having it on at low speed, and having a temp alarm set for 24c so it would ramp up when the lights kicked on. Problem was, if you then cycle through the settings for any reason you will reset alarms (support tells me this is by design so you are forced to clear and reset alarms when they occur), if you forget, you won't get the ramp up.

Or as mentioned there is completely off, and then on at a set point. If your situation stays under the set point for any significant amount of time, and this is your only fan, you might run into air-exchange problems, or it might bounce from off to on frequently.

It will work, and is working for me, just not as I had hoped.

I agree, I wish it would let you set a minimum fan speed too, I would like that!
