That's really helpful! Thanks. I also have two lights and, likewise, having two allows me to run the lights at a lower setting and have better coverage. I've been thinking about running the lights at night when it's cooler outside. So far, high heat hasn't been my biggest problem.For a 4x4 tent I would do a 8" AC Infinity so I could get my cfm at lower rpms and keep it quiet. I run a 6" units in my 2x4 and 3x3. Always exhaust air from the top of the tent,,,, Heat rises. I use my exhaust fans to control temp and exhaust excessive humidity into the grow room. The central A/C system has enough capacity to extract the humidity from the living space. I use a Inkbird control to control a 1 gal or 1.3 gal humidifier in the tents when I need to get the RH up in the fall and winter months mostly. I have way more total lighting power in my tents than needed by most peoples measure. In the summer months I can turn the dimmers down, keeps the lights close to the plants and still maintain fantastic light coverage and keep the temps down. Come fall and winter I can raise the lights higher, turn the dimmers up and use the extra heat the lights put out to heat the grow space. This does require a tall tent. I also always keep at least 3ea. 6" small circ fans in the tent. 2ea. in the grow space and one above the light. Always keep them on low to gently move the plant tops around and one above the light on low during the summer months to cool the lights and have the warm air ready to be extracted by the exhaust fan. On high during the fall and winter to force warmer air down into the grow space. Good Luck!
My tent is in a separate room that vaguely resembles a lung room. We use it for other things, too. I have been keeping it in the low 70s. I have two 240 watt LEDs, though, so maybe a T6 would work for my tent. During the day, I am pulling outside air through the room using an attic fan on one side and an open window on the other. We're supposed to have 80* weather the next few days, however, so I'm worried about that.I agree. I have a T6 in a 5 x 5 and so far it's keeping up with two 2000w LED's but I would like a little more headroom and wish I had gone with the 8" fan. I've set the lung room temp to 73* and the tent is running between 76* and 80* with lights on and 73* to 75* at night. RH is averaging out to around 54% but I'm dehumidifying the lung room. VPD has averaged between .84 and 1.37
The ad says the controller also works with their clip-on fans. That's an interesting idea, so I'm thinking of trying one of those, as well.Those controllers are easy to learn to use and have a bluetooth app. You can just run them in simple on/off mode until you learn how to use the advanced features (you can create scheduling and triggers to change fan speed at different temp/humidity points).
It also provideds a VPD (Vapor Pressure Deficit) monitoring function which is *very* useful, imo.
I remember my first T6... and now I have 3. I ended up adding fans on 2 of the 4x4x7 tent ports (intake & exhaust for heat control), and I setup an additional 2x4x7 sprout/clone/veg tent/rack and it has a fan..
The AC 67 is a good choice... and if you start with 1 fan, you have the option to add another later... say, if you get a bigger hotter light and need to vent more heat or add a filter, etc.. etc..
The 4 port controller can control 4 fans independently BUT it only has 1 temperature sensor, and so advances features can't be setup in multiple tents - just a heads up on that.
Sounds good! We don't have a basement. Using mesh to filter out bugs and such is something I'll definitely do.Hey, I've bought cheap 6" inline fans and added BBQ fan controller's with hot glue on the housing to attach. I then 6" to 4" Y for 2 lines as cool input air sucked from a cooler unheated lower basement with fine mesh drawstring bags ( $1 Dollar store ) over both ends...Its not perfect but keeps out bugs and heavy dust.. My tents exhaust is another cheap 6" inline with same controller and filters, no Y added. I'm not worried about the smell, I can adjust the output air to be close to the input. I add input air because I like to add cooler air into the bottom of my tent.
I'm thinking I need both, too.Thinking you need both. Dehumidifier and upgraded exhaust and supply. I’m pretty sure all ac infinity cloudline models with temp & rh control come standard now with the newer Bluetooth enabled 67 controllers. Folks that are getting outdated controllers are probably getting old stock from there local grow shop or other online retailer. Order direct from ac infinity and you’ll get current hardware.
For clip fans, I'd just stick with normal 120v style plugs (the special clip fans can't plug in a standard wall socket), and I'd save controller ports for inline fans.The ad says the controller also works with their clip-on fans. That's an interesting idea, so I'm thinking of trying one of those, as well.
If you want to do that I would recommend ordering direct from ac infinity and ask to upgrade to the 69 controller from the 67. The 69 has 4 ports and each can be independently controlled. They have a wifi version and non wifi version of the 69 controller. The new occillating fan is why I am upgrading from the 67 to the 69. I’ll have the exhaust, supply, and occillating fan on one controller and wifi capable.The ad says the controller also works with their clip-on fans. That's an interesting idea, so I'm thinking of trying one of those, as well.
That's another thing I hadn't considered. They probably cost more, too. However, I'm sure I won't be operating more than one tent. I'll give it some thought. I don't have to buy everything all at once.For clip fans, I'd just stick with normal 120v style plugs (the special clip fans can't plug in a standard wall socket), and I'd save controller ports for inline fans.
I never change the speed on my clip fans (Hi) or turn them off.
Sounds good! I couldn't find the model of the controller on the Amazon ad. Sometimes I suspect older models are dumped on Amazon. I would definitely want the WiFi version. I'm using SensorPush for the temperature/humidity sensor, and it has WiFi and Internet access, so I can check my tent from anywhere.If you want to do that I would recommend ordering direct from ac infinity and ask to upgrade to the 69 controller from the 67.

Don't even lean. Get it. I have one and I love the control it gives me.So far, I'm leaning toward the T6 and getting the WiFi controller. I still want to read through the product information.
We're about to have the hottest weather so far this summer. So I made some changes based on what I've learned in this thread. Until I get a better fan, here's what I've done.
I made two exhaust fan assemblies with 200 CFM fans to fit into the tent's ports:

Here's what the fans look like when they're installed in the top of the tent:

I opened the flaps at the bottom of the tent that have fabric mesh to keep crud out of the tent:

So far, these fans seem to be working well. The power supplies are running hot because the fans are drawing too much power. The fans are 1.5 Amp and the power supplies are rated at 0.5 Amp. I'm surprised neither of them has died. I ordered a 5.0 Amp power supply that will have more than enough power for both fans. It's due to arrive tomorrow. I plan to repurpose the smaller power supplies to add fans to the heat sinks on the light panels.
Meanwhile, the outside temperature is supposed to reach the high 80s today. I'm blowing cool outside air through the room. The room temperature was about 75* at noon but it will get hotter. Inside the tent, it's 83* with a RH of 54%.
So far, the plants seem fine, even though they've been through hell because of the newbie grower.

I'm waiting for their 9" oscillator.If you want to do that I would recommend ordering direct from ac infinity and ask to upgrade to the 69 controller from the 67. The 69 has 4 ports and each can be independently controlled. They have a wifi version and non wifi version of the 69 controller. The new occillating fan is why I am upgrading from the 67 to the 69.

I have one of those six-inch fans out there now. It's kinda old and noisy, so it'll have to be replaced soon.Guerilla pole fan....
Bought a cheap $15 six inch fan and converted it into a pole fan. Gonna pick up one of the Honeywell Turboforce oscillators and see if I can do the same.
I probably will. I've spent a lot more on this project than I imagined when I began. Now we're talking about another couple bills for a fan. The 120 mm fans are doing a good job, but they're noisy and dumb, meaning they only run at one speed. I could get a speed controller, but that would be manually controlled. When thinking about the cost, I just have to keep focused on all the great cannabis I'll be able to grow. I'm already looking forward to the next crop when I will have much better knowledge and equipment.Don't even lean. Get it. I have one and I love the control it gives me.
Okay. I'll watch for that.I'm waiting for their 9" oscillator.
Fk ya.....that's my kind of fan and set up..I like, Is that just a coupling cut in half to attach it?Guerilla pole fan....

My grow spaces should be fine with 6”. I got two and haven’t installed them. I’ll run them next grow mounted low for circulation above the pots.I'm waiting for their 9" oscillator.

BB - I've been in this game for a second and the advent of technology is certainly making it easier for us to monitor and steer the environment we want our girls to be in. That I don't have to take leaf temp readings and then try and figure out VPD/KPA is, in itself, a selling point for me. Before you pull up on the purchase of a fan, my tent is 5 x 5. Bigger than most on here which is why I'm waiting for the 9". Most tents will be fine with a couple of 6" circulators. Right now I have the 6" mounted on a pole in the corner of the tent pointed at the top of the plants to keep a gentle sway going while I have a ceiling mounted Honeywell 8" turbo force fan pointed at the lights to keep them cool. Right now the girls are vegging so I can keep the bottom intake vents open but come flower flip time I'm going to have to close the vents for dark period on 12/12. When that happens I'll remove the Honeywell off the roof, run some 6" duct from one of the 6" bottom ports and connect it to the back of the fan using it as both an intake booster to make up for the vent panels being closed and an air circulator for under the canopy. The 6 inch will be used for lamp cooling.My grow spaces should be fine with 6”. I got two and haven’t installed them. I’ll run them next grow mounted low for circulation above the pots.

What I like about the AC fans is they're 10 speed so the controller will adjust fan speed to condition and it's oscillating.
