I think you’re “done” with this bud. Many a threads are on here with “what to do” ideas.
Look to set this up ASAP and next run to get humidity in the 45%.

A few other things I got locally from grow shops. Quality seeds are important. Greenpointseeds.com is always having bomb sales, ship from Colorado, and are top quality. Soil from local grow shops but can also buy from online. I went cheaper on light, but I wouldn't do that again. Get good quality lights.
I bought this ikea cabinet My plan is to cut a hole in the top with a 4in hole saw and put in a duct fan like this and run the duct out the window. The only problem is getting the printer out of the cabinet when the print is done but I figure it's easy enough to build a sliding platform for that.
The lights are one for 18 hours and off for 6. Mine come on at 4 PM and go off at 10 AM.
I'm just using a power strip with a built in timer. Like this. Half the outlets are on a timer, the other half are always on.
I used to keep my fans on the timer as well, but I recently swapped them out for quieter models that are less powerful/noisy. Now I just run the fans 24/7. My main fan has a thermostat in it and will slow down and speed up depending on the temperature in the tent. I find it convenient as I work from home and my tent is in my office. If I didn't sit in the same room as the tent all day, I'd probably just stick with a cheap duct fan like this. It's easy to overdo it with fans in a small tent. I originally bought a big 6" fan but it was overkill. My carbon filters died fast because I was pushing so much air through them and it made more noise than I could stand.
My setup is pretty simple and cheap, but it grows more than I can smoke and I don't have to spend much time worrying about it. I pretty much just did a little research, went on amazon found a grow tent, and bought all the 'people that buy this also buy...' stuff.

Get this (or something similar, might be cheaper other places) and run it next to your space bucket. For one plant in a bucket this should be more then enough to keep smell out. Just set this up next to your bucket. Pull air through the filter and push it out the top of fan.
I bought a laser cutter and the stipulation was that I must have excellent fume control if I were to get one put in the warehouse. I didn't want to pay the crazy costs of a fume extractor. So, over the weekend I designed and cut this one instead. Here are all the parts necessary if anybody is interested in the costs. I chose very expensive filters - almost the most expensive I could find - and still came in way under the cost of a typical fume extractor:

So I'm ready to finish the assembly, but now I want to engrave something funny or cool on the door. Any good ideas?

I haven't heard of anyone doing that. I guess it could work, but how effective would it be? I can't say. If you wanted to experiment, maybe get some P100 filters and test it out on some alcohol or acetone fumes.
What I do to vent fumes, and I suspect what most people do, is to simply run a duct with a fan to a window. Any 4" or 6" inline duct fan will work well. They're easy to mount, they're cheap, and they're very powerful.
This 6" inline fan is the one that I use. I have it plugged into a speed control because I rarely need it's full 400 CFM sucking power. I usually use it at about half power. I mounted it under my workbench with the output duct permanently installed in an adjacent window. I keep the input duct retracted under the table so I can pull it out when I need it.
I don't have any fancy system for this. When I'm cleaning a part and I need to vent the fumes, I just pull out the duct from under the table and rest it on the workbench next to the cleaning vats (being careful not to suck up any paper towels or nitrile gloves... for the tenth time). It's a bit ghetto, but it's very effective. I usually can't smell anything when the fan is running. Even isopropyl alcohol fumes get sucked away faster than they can reach my nose.
Hope that helps.
I used this one:
https://www.amazon.com/gp/aw/d/B01M7S46YZ?psc=1&ref=yo_pop_mb_pd_title
Along with a 3d printed duct for the back at the machine, with the blower positioned at the end of the hose. Works great.
Thanks for the post. I have seen a few of these before, but this one motivated me to finally order everything. I have been wondering what I was going to do this summer. Currently my rigs costs me about $8.50 a day in electricity, but saves me about $5 a day since it is literally heating my entire house.
@ .12 kwh the fan at full speed costs $.55 a day. I ordered a bigger tent and 2 of the fans. Hopefully I can run them at some lower percentage (they come with controllers).
This is what I ordered:
A charcoal filter works for indoor use. I printed this adapter on my ender 3:

And I ran it through a filter with these things:
It works great for me, and I'm very sensitive to the resin fumes.
If you are only using butane torches and a pickle pot, you may be able to get away without one, but it is healthier if you use ventilation. You are going to inevitably burn oils and other contaminants and that should not be going into your lungs.
A 200 CFM, 4" duct fan can be used with a dryer hose and a 'vent periscope' box to make a permanent in-window vent system. Add some duct insulation and it won't bleed heat. The basic setup is about $60.

I'm using Acetylene, and that gives off soot, so I *need* a vent system. I will probably add a stove hood from the remodelling surplus store just for better smoke collection.
It’s this tent vented with this fan with a carbon filter attached. They’re both pretty cheap but seem to be working fine so far.

Hello there, I recently started growing and purchased all new items. The fan you chose simply won't work. You will be very disappointed in the performance. I was going to use that fan as an inflow booster with a pre-filter. I quickly returned it because it just did not move enough air. The fan could not create positive pressure in the tent. I then tried this fan: https://www.amazon.com/gp/aw/d/B01M7S46YZ/ref=mp_s_a_1_3?ie=UTF8&qid=1495901534&sr=8-3&pi=AC_SX236_SY340_FMwebp_QL65&keywords=4+inch+inline+fan&dpPl=1&dpID=41G0I96VBVL&ref=plSrch
I ended up returning that one as well because it was advertised as 200cfm and it was not moving anywhere near the same air amount as the first fan I bought. I then broke down and bought the same fan I originally purchased as my outflow fan and filter. I bought just the fan for 56.00 as an inflow fan and put a pre-filter on it.
https://www.amazon.com/gp/aw/d/B00D7M6692/ref=mp_s_a_1_1?ie=UTF8&qid=1495901249&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=4+inch+inline+fan+carbon+filter+combo&dpPl=1&dpID=51REkA1uNbL&ref=plSrch
If your house has conditioned air, you might be able to draw off of that to cool your cabinet in the attic. A small cabinet can be cooled by a 4" line and a real exhaust fan. Install a bathroom fan style ceiling grate in an out of the way place (spare bedroom closet?) and no one will know what's up there. Just, uhh, don't pull from the bathroom... Not only would you suck bathroom smells into the tent, but if your bathroom fan is powerful enough and the door is shut, it could conceivably pull air from the tent into the bathroom 😬
Look for a fan that can do in the neighbourhood of 200cfm, preferably with a speed controller. I have this Vivosun one: https://www.amazon.ca/dp/B01DXYMGOM but if you're not on a budget, this one would be excellent: https://www.amazon.ca/gp/aw/d/B06ZXWN3BG
Avoid the super cheap "booster" fans, they're only useful as an add-on in the middle of a long run.
I have a duct fan blowing into a carbon filter. It does a great job keeping the smell down.

will clear your humidity out in a minute or two. get a cheaper humidistat if you want, just needs to turn on and off at a set point, but the inkbird is a good value.
If you aren’t planning on getting a bigger tent I would stick with a 4” exhaust and a 4”/6” carbon filter. Here’s the link for the fan and one for the filter . I use a bigger fan and filter personally, but that’s because I plan on getting a bigger tent after my third or fourth grow. Based on the dimensions of your tent this should be a solid setup for you even if you go up a bit in the future.
I used plastic ones on two bath renovations, very quiet, and wont rust.
VIVOSUN 4 Inch 195 CFM Inline... https://www.amazon.com/dp/B01M7S46YZ?ref=ppx_pop_mob_ap_share
You could do a space bucket style build if you are lacking space and dont mind some DIY.
But if you want a tent style this is kind of like mine
Tent just used this size as it is standard some companies will make smaller ones.
Lights good for a 2x2 tent
Inline fan exhaust
Booster fan good for air in
Filter wont need this until flower
I have a 2x2 tent and a Can Fan S-400, which was what my hydro shop recommended when I was getting started. There are no doubt cheaper 4" fans on Amazon, but it seems very well made and has a 5 year warranty. I also have a Vivosun 4" fan, which I run freestanding with an extra carbon filter attached to scrub the air during harvest. It works, and isn't especially noisy, but feels very cheaply made.
I've heard people say that a 6" fan turned way down can quietly move a lot of air, but haven't tried it, and a 6" fan on full speed could suck in the tent walls too much or even tear them. (I get pretty strong negative pressure with my 4" fan on full!)
I haven't used any fans with an integrated speed controller, but the external fan speed controllers that actually reduce voltage are vastly superior to the cheap ones that just rapidly flip power on and off -- depending on the fan motor type, the latter can damage the motor or produce loud buzzing as you slow it down past a certain point. When I tried one with mine, anything below 80% or so started buzzing. The better controllers cost a bit more ($70 vs. $15), but since it's actual industrial equipment it should have good resale value.
My tent is in my home office and I don't find the noise problematic, if that helps.
For a 2x2 tent, it's probably more effective to control humidity in the surrounding room, rather than putting a dehumidifier in the tent.
I can step in and answer a few on from my own tent.

2. I personally dont use an intake fan, just leave the mesh openings and Duct openings on the bottom open.
3. refer to Autonomous incoming reply.
4. I'm using an APC 7900 switched PDU i got off ebay for $85
5. I'm using this fan ( https://www.amazon.com/VIVOSUN-Inline-Variable-Controller-Ventilation/dp/B01DXYMJ94/ref=sr_1_4?ie=UTF8&qid=1518212723&sr=8-4&keywords=vivosun+6%22 ) Plus side is this fan is indeed quiet and runs at 60watts for me.
6. I've got a blower style fan circulating the air inside i had this fan before the tent so i just used it ( https://www.amazon.com/gp/product/B00E1LYHTE/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) .
Still considering getting another Vivosun 6" as intake with a carbon filter just to eliminate dust on cards and making maintenance easier
7. Tent i use 48 x 24 x 84 (https://www.amazon.com/gp/product/B00WMBQZ90/ref=oh_aui_detailpage_o02_s02?ie=UTF8&psc=1)
Fits this shelf with Rigs mounted with a ton of room( https://www.amazon.com/Tier-Heavy-Non-Corrosive-Metal-Shelving/dp/B076GXK3ST/ref=sr_1_2?s=hi&ie=UTF8&qid=1518213252&sr=1-2&keywords=Hyper-Tough-5-Tier-Wire-Shelving)
8. $199.51 total including 25feet 6" duct, hangers and an 6" round to 6"oval to be mounted through the window. (Not including Shelving the rig is mounted to inside)
I don't smell my plants with my 4x4 closed. So the same thing should apply for you. Since you are venting outside you should be fine. It may be an light odor in the room. But it shouldn;t smell up the whole room until you open the tent.
This is the best on teh market. https://www.amazon.com/AC-Infinity-CLOUDLINE-S6-Controller/dp/B07FPFVZTZ/ref=sr_1_6?keywords=ac+infinity&qid=1554815892&s=gateway&sr=8-6 There one with a humidity control as well. If not https://www.amazon.com/VIVOSUN-Inline-Variable-Controller-Ventilation/dp/B01DXYMJ94/ref=sr_1_3?keywords=vivosun+6+inch+fan&qid=1554816051&s=gateway&sr=8-3 Will be more then enough to vent the tent out the windodw.
Wanted to ask which fan you recommend. I was going to go with one of these: https://www.amazon.com/gp/product/B01M2XG0E1/ref=ox_sc_act_title_1?smid=A3I2VACYSJR5AQ&psc=1
Maybe even the 8" and turn the speed down if needed.
This paired with the bofa (while expensive) might give me the sound levels that would let me run this for a lot longer than just a few minutes at a time.
Thanks
Sorry it should be inline fan
Here is one
VIVOSUN 4 Inch 195 CFM Inline Duct Ventilation Fan Vent Blower for Grow Tent https://www.amazon.com/dp/B01M7S46YZ/ref=cm_sw_r_cp_api_i_1vfrDb7H5Y14V
Get a grow tent , an inline fan and 8-inch flexible ducting . Put the fan in the uppermost part of the tent so it evacuates hot air, then stick the ducting so it blows out the window. Problem solved!
I just went through getting the temperature down in a dining room / sun room at one of my vacation rentals. In my case the room stayed up to 15 degrees (fahrenheit) hotter than the rest of the house during the summer. It has 9 windows or glass doors facing southwest / southeast, which in Texas makes for a pretty significant solar load.
I changed three things: One was to put in reflective insulated mylar sheeting above the room - that was good for at least 7 degrees. I highly recommend this as a first step if you can fit it in your space.
The second was to alter the AC ducting by installing a variable output high capacity inline duct fan into one of the ducts feeding the room. This fan runs continuously, boosting the amount of air that comes into the room when the AC is running, and when the AC is idle there's still output from that vent as it pulls a bit of air from all the other rooms. Made a 3 to 4 degree improvement.
The last change was to install white cellular blinds from Ikea on all the windows and doors. When pulled down halfway they keep the room 1 to 2 degrees cooler and when pulled down all the way they keep the room 2 to 3 degrees cooler. EDIT: We actually used those in a different room. In the sunroom we used a lighter colored model of these blinds. Had we used the cellular blinds we'd have probably gotten another degree improvement.
All of these changes are relatively inexpensive and the net result is a room that's within a couple of degrees of the rest of the house.

Where to start with my update.
I began collecting the parts for the controller. I am using a BME280 for the temp and humidity sensor, this little screen for reading conditions at the chamber, 8 channel relay to control the various electronics, this fan and this filter for fresh air.
Here is an album of updated photos. The first is a blast gate controlled by a servo to control the fresh air flow. When the fan turns on the servo will open the gate and allow the fan to suck air out (more on that later). Next up is the freezer with the collar on. Its not put together properly yet but just a rough test fit shows its looking good. Then I have two inside shots of the chamber itself.
After talking with someone who understands air flow much better than I do, I changed the position of fan and filter as well as direction. The fan is going to suck air out from one side and the other will have the filter on it. This will keep the lid down, where as if the fan pumped air in it could lead to a pressure build up and the lid may crack open slightly. The elbows are put in so its not just the top air that is circulating. I am thinking of turning them so they don't point straight down but for now its good.
The inside shot show the slots made to hold up to 7 bars. I am going to seal in the collar with a piece of wood on the top then fill it with spray foam insulation and silicone it to the freezer.
The other thing that has changed since I last posted was that I was going to try to do the code myself. As I got parts in and tried to put something together it became clear there is no way I can do it. After searching around I put out a bid on upwork.com and now I am working with a friendly fellow from Nepal. We haven't gotten to far but I am excited by his proposal and he will be adding the ability for me to control it from a webpage.
Anyway that is it for now. I can see there isn't much activity on this post or another related post but I am going to follow through with the updates because in my searches for this project I cam across a lot of half finished ideas and projects. RemindMe! 2 months
Using a vivosun 195 https://www.amazon.ca/VIVOSUN-Inch-Inline-Ventilation-Blower/dp/B01M7S46YZ got mine on fleabay. It's ok, I don't know if its bearings or bushings, its quiet ish. Cheap as fuck, the casing has no seal so it leaks, I fixed by using metal duct tape on the joint. 195 cfm is the unrestricted flow from the outlet. So after resistance of the ducting its reduced. Also the resistance of the filter (has to push or pull through) it drops even more. I'm 2x3 x 6.5, on hot days I dont get the airflow so I had to put in a second extract. I expect colder weather will be perfect for it in my particular circumstances.

Connected to 8' aluminum duct
Here is a pic of my setup
The filter and in line Fan I use together cost about $100. To connect it I 3d printed this part and super glued it to the back vent and put some sealer on. You could just buy a connecter tho.
Altogether about $600
$450 for the printer
$100 for the filter
And those minis only cost $20-30 in resin to print.I’ve printed other stuff som I’m not exactly sure.
And a bulk IPA pack for $20
This isn’t necessary but I also got an Ultrasonic cleaner for cleaning the prints when they are done.

pot growers run these for years at a time... literally non stop 24/7 for years.
if you need to duct any of it, you can use dryer hose for the outlet, but get something more rigid for the intake so it doesnt collapse.

bought this with some duct and a carbon filter
So I made this thread recently about a clone I bought on 4/20/19.
​
Now, a bit of time has passed and it's grown a bit more, but unfortunately still under very inadequate lighting. The temp and humidity were wrong this entire time, but I seem to have stabilized that. I plan on ordering this grow tent, just ordered this LED light, and am looking at this (or this) in combination with this to bring it all together. Anyone see any reason why this wouldn't be enough?
Set up was super easy, old port screws right off and you screw the new one right one and then slap on a filter and a fan (any carbon filter should do but here’s what I bought that works well)

Anyone know if this is something I should replace too? Still under return period.

Yea my thermometer is facing direct light on soil level.
I’ll crank it up and see hat happens.
Thanks
Plywood box, HEPA filter, and one of these: https://www.amazon.com/dp/B07P6J3L1N/ref=cm_sw_r_cp_apa_i_EvdrDbXKMBRFF
Thank you! Very helpful. Does one of those heat recovery devices serve the whole house by itself? Is the humidistat built in or a separate product with these? Also, the airflow on those you linked to seems very low compared to the extractors I've been looking at (l/s) - why is that?
Do either of these look any good?

Our house is 80+ years old. Cold outer walls. Terraced, on a slope so property adjoining one side is higher ground level than ours.
Sorry for all the questions, total novice here!
So really this should do the trick?

Yes, there’s a blower like this one https://www.amazon.com/dp/B07HFQTJH9/?coliid=I28Q2FG7UOZXSO&colid=HLB6M8WGEQCM&psc=0&ref_=lv_ov_lig_dp_it to pull through carbon granulates.
More research points to this being pretty quiet

But that perhaps the laser would be louder than the fan anyway? Or that I could build a wooden enclosure to lower the noise? And buy a 6 inch hvac of 240 cfm?
And maybe this would be quiet and powerful enough:

It's not the zone controller that is the issue, it is Nest (and most other WiFi thermostats) need a C.
Options:
I wouldn't sleep while it's running. But the one you linked won't ship to me.
But i found a similarly powered exhaust fan.
This one
I've already found tubing and a filter to use.
As for noise I also have a FDM printer in my room that I run occasionally, so I'm sort of conditioned to it.
Thanks for the reply brother. I did the same thing but I had this running on the bottom part of the tent.
Thought about doing the same thing that u did but my filter/fan in the tent is set up at the top. I was thinking that the air coming in will just get sucked up by my tent filter. I'll definitely give it a try tho, really want to try photos.
It’s possible because there is no airflow, also it will cool your tent down. I bought 2 fans and some 4” ducting from amazon and probably paid about $50.
Here is a link if you would like to check them out.

I’d go with this at the smallest

I have one size down for my 40w epilog and would like a bit more flow. Of course my run is not efficient so I will see how I feel after fixing that.
You can never have too much exhaust flow IMO

Are you using this fan: https://www.amazon.com/VIVOSUN-Inline-Variable-Controller-Ventilation/dp/B01DXYMJ94
It says "Max Ambient Temp is 113℉ / 45℃" I assume your tent is always above that temp. Do you have any issues?
How many of your side vents are open? Do you have any fans inside your tent moving air around? I have a 4 in PVC pipe that is inserted into one of the 4 inch opening in my 3x3, to allow unrestricted air into my tent.
For 25 dollars, you could buy one of these, and have it pull fresh air in.

Forgot to mention. This is the bottom floor of a two-story house, so no access without tearing through the ceiling. I have remote control outlets, which could work for turning it on and off.
Searching through amazon is a mixed bag, exhaust fans turn up a few decent results like https://www.amazon.com/dp/B004ALCRDI/ref=twister_B06XWPJ28N?_encoding=UTF8&psc=1, but the majority are bathroom exhaust fans that vent out the side, or booster fans that replace the ductwork i can't reach.
Is there a more specific term for what i'm searching for?
