We all know what that growtent is actually going to be used for when this video is over. Nice way to get LMG to buy your grow equipment for you.
Tomatoes and bell peppers of course!
They'll use it and another 5000 tents like that to pay off their new lab.
Wooo Alex! I want to see an LMG employee get a ton of "plant accessories" in Intel 5K ahahaha
Hey maybe he want's to grow tommatos
Isnt weed legal in canada? why would he grow his own
You should just mount a radiator outside your window and run your computer's water cooler to it. In fact, you could water cool the rest of the room too! Perhaps you could call the concept "Whole Room Water Cooling". Maybe Luke's dad can help?
I can't see anything going wrong!
.... This feels like air conditioning but with extra steps.
i mean the issue with whole room was that they tried to cool multiple pcs with 1 loop. the basic concept isnt stupid at all.
That's a heat pump
I mean, for one PC close to the window it's not that crazy
@@Chris-rg6nm A heat pump would entail a compressor, condenser, evaporator.
At which point, that's the air conditioner aspect he wanted to avoid
I love how he's able to machine, cnc, and print everything... except the grow tent itself. I wonder what kind of toys we can get to make our own Mid Tower sized Grow Tent.
Nobody knows how to sew. lol
underrated observation
Need to level-up the sewing machine skills.
Could have made an acrilic box to put the PC in too.
The "box" could have been plywood, cardboard, or Styrofoam, but then you would not have a cool grow tent in your video that was sent to the show free.
You could also just run the duct or ducts from the exhaust ports of the PC which is already a box...
I continue to love the series of weird ass cooling solutions that Alex comes up with.
Many of these ideas seemingly came from inside of this growtent
With all the engineering that went into this, it may have been easier to just design or modify a computer case to exhaust out of a pipe leading to the outside
Yeah, could probably just have made the hose adapter fit the backside of the case and kept the output the same because that fan is moving so much air, that nothing is escaping out of the computer case :D
Realistically, that would of been a boring video. If one was actually made for it.
Well thats the next video ofc
Um, that would need more work
@@Hacker-cw9lc not much more
Alex went from being "he's okay but a little quiet" to one of my favourites on LTT.
Alex and Jake are going to be key in order for Linus to realize his goal of becoming just a CEO
Also Anthony, they got confident and are showing their true colours 😊
Alex is the MVP of LTT (for me) I love all of his video ideas. S-Tier for me! I hope he reads this.
thats what happens when in your almost every project video
@@dr.saimamasood8314 does Anthony prefer they/them as pronouns?
The ducting needs to have as few bends as possible. Each bend affects the airspeed. Also placing the fan as close to the exit as possible should improve air exchange.
Very good point, mount at the exit... Inside a noise insulated box
@@iHelpSolveIt By that point you might as well just put the PC in another room and run cables through the wall.
@@5thwiseman wont solve the other heat generation unit in the room... The high output heat source called the human body.😂
Placing the PC and "grow tent" closer to the window would also make a lot of sense, but this is LTT!
One thing he forgot to do was put a grate over the outlet to prevent ingress of wildlife and or rain etc
Alex, you may want to put a covering over the exit to prevent bugs from entering.
Interesting idea though, thanks for sharing!
Why? The fan will likely be on all the time, so bugs can't enter.
@@sdspivey ohh for sure they can, don't underestimate some bugs.
@@sdspivey it won't be running 24/7
@@tahiraslamm Why not? The majority of people never shut down.
You can use the one way damper for an dryer exhaust vent.
Since you printed 2 of the angled hose fiting i would recommend putting one outside with a mesh over it, othervise you will get rain going inside the tubing and insects/birds nesting in there as well.
No he’s got to use that for the second grow tent he get. I mean he did make two of everything
very good advice!
That fan is pulling 350cfm through a six inch duct, which means the air is exiting at 52.1 miles per hour; ain't nothing going in there.
@@hlaw2830 you do realise that the fan is not going to be on permanently . . . not everyone uses their pc 24/7
@@hlaw2830 I think you are missing the part where the fan is running on it's lowest setting. No way it's doing 52mph. Also BensCast is right.
Anyone noticed how Alex always gets a reason to use the big laser or any of the other shop tools 😂😂😂
When you have a hammer everything looks like a nail, only you have a laser and a 3D printer.
They have to do it can be used as depreciation for the business and potential tax write off if Canada have similar business tax implications.
I mean i'd do the same
He better find a reason to use it. They have to pay it off somehow.
Having access to a Trotec laser, it never gets old using it.
You should route the intake from outside as well. This setup will drive up the home's AC costs
But that would ruin the point in the days when it's too hot outside
@@olutukko2681 no it won't, because it will be confined to the grow tent. Moto is 100% correct. This setup is pulling outside air into the home by creating a vacuum (remember when he said how much air was being pulled in under the door? Where do you think that air is coming from ultimately?)
@@olutukko2681 the computer would run hotter yes that is true though. But it shouldn't be running too hot.
@@glasshalfempty1984 oh right yeah that would work :D I didn't think the concept correctly
That's what I was thinking too
This WILL increase your air conditioning bill, since you're creating negative pressure which sucks hot air from outside. But if you only care about comfort, this will work. Also worth noting it's probably just as effective, and less work, to simply extract air from the room rather than enclosing the PC.
This.
Yes, I had the exact same thought, just put an extraction fan on his elephant window BAM work done.
So all he did was basically crack the window and put a fan in it?
@@Lexaire Pretty much, yeah lol. Although it could be slightly more effective since it's pulling out the warm air from directly around the PC, the added hassle might not be worth the slightly cooler room.
This is kinda a fun one -- If the air outside is HOTTER than the air exiting his PC he'll have a net worse experience, BUT if the air leaving the PC is HOTTER than the air outside the air coming in via negative pressure will actually be a net positive as it'll take less energy to cool the outside air coming in than to cool the air being pushed out. His air quality is going to be garbage though and you have to take into account the electrical cost of running the blower.
Ditch the tent, and 3d print a new panel for your pc with a duct attachment. Or use the spare duct and cut out a hole in one of the existing panels. Your pc temps should improve too.
Good idea
It's a bit weird he didn't go this route, or at least do it at the end of the video.
Nah, this is a typical project by Alex. He can't plan 30 minutes beyond what he's doing. Just a total hack with a pretty face and connection to Linus.
@@oodlespring Pretty rude thing to say about someone you don't even know.
@@oodlespring I think that's taking it a bit far, coming up with original ideas and topics worthy of a video while being easy enough to finish in a timely manner is no simple task. While my idea is probably more practical, I doubt it could pull the same views.
Definitely would recommend 3d printing some ceiling mounts for that ducting. Keeping it up in the ceiling would be even better.
For keeping it out of the way sure, but for performance it doesn't matter. Air only has 1 way to move through there.
@@wickedwonka999 it can hurt the airflow though? due to minor kinks and whatnot
@@DeathKiller362 sure, but so can the extra length of tube they left, extra distance is harder than a curve
@@DeathKiller362 and even still, that 6" inline fan he used moves upwards of 400cfm. That tent is 2'x2'x4x so 16 cubic feet. Trust me, there is no problem moving that air.
Making content from tips the employees do on their own homes is pretty awesome, hope to see more
I feel like this is more of a room air circulation problem than anything. A few fans strategically placed to keep the air moving around inside of the apartment and thus creating an equilibrium in the rest of the apartment between the warmer air from the pc and cooler air from your AC system. But I'm no expert on thermodynamics so take this with a grain of salt.
This would involve opening the door, which is not an option. However a door vent would greatly increase the overall air returned to the intake and prevent the door being closed from being a problem while also preventing unwanted shouting from being an issue. It would also help to have a smart thermostat like a nest with a wireless addon for it placed inside of said room. It may cause the rest of the house to get alittle cold while he's gaming, but overall a much better solution then him creating negative pressure and sucking out ALL of the cold air from his apartment and forcing his AC to run continuously while it struggles to cool air being poured in from any small cracks and holes in the walls and ceiling, probably mostly through any kitchen vents, bathroom vents, etc.
I was thinking the same thing. An extractor fan at the windows would do about the same thing
Like he said he isn't allowed to open the door. Also that seems a lot more inefficient in terms of cooling because you're using more fans and use more energy than just a single fan that direct exhaust, while cooler ambient air enters from different rooms cooling the rest of the house at the same time.
@@Smashachu Yeah he could probably 3D print a little piece that tapers down to the size of the Crack under the door, and hook it to a vortex fan. That should absolutely dump fresh air in, and the positive pressure will force stagnant air out the bottom of the door wherever the 3D print piece didn't fill it up
3:20 in a grow tent setup you need those metal pieces to hold up the lights that will help the plant grow. Some people also use them to hang ventilation equipment pulling air into or out of the tent.

These bots are the worst.
2:45: I'm too cool to read the directions.
It's hard to say that the grow tent is the cause of the room temp decrease. Venting the room air (grow tent or not) cause negative air pressure in the room confirmed when you said cool air from the rest of the house was rushing under the door. It's entirely possible that simply venting the room and having extra cool air from the house rush in cause the room to be much cooler. Try the same test but without the grow tent, still vent the room.
That was the first thing I thought -- this seems like a misunderstanding of how the cooling of a home normally works. It's a closed-loop system. If this is constantly forcing air out, then somewhere else fresh outside air is being drawn in, which means the rest of the home is warming up due to bringing in warm outside air to replace it.
Rather than the air conditioner having to only cool down the heat from the PC, now it's having to constantly cool the heat from the outside air!
The real issue here is just air exchange with the rest of the home where it gets an opportunity to be cooled by the air conditioner.
@@PabloEdvardo The house isn't air conditioned tho. If it was, this would of course be pointless. He literally compared buying a grow tent to a shitty AC unit at the start.
I disagree, he is basically taking his PC, ~700W heat source, and not allowing it to vent directly into the room. The fresh air exchange is just a necessary part of the overall system.
It's not just that. It's even worse. He is pushing air outside. Which means that air from the outside the house is also rushing in. This means if your house is still cool - and outside it's hot - he actively HEATING the house up.
Sure his room may suck all the nice cool air from neighboring rooms. But what he actually is doing is wasting his cool house air and exchanging it for outside hot air.
This thing heats up the house/room. Just for a small period of time where this single room pulls cooler air from neighboring rooms it seems like it cools the room down.
This is a really really bad idea. Especially on hot days.
@@tagg8233 at 1:40 he says, "I have air conditioning that's in the apartment"
Used these tents for many things. Having this connected to the exhaust of the house air exchanger makes a big difference. In winter flip it to keep the heat in.

_all you need_ is
a grow tent
Ducting
Duct tape
Milling machine
plastic parts
Wood
Bolt fittings
blow torch
mineral oil
industrial fan
3d printer
CAD program
and a Freaking laser cutter
This is a convenient accessible & cheap little diy project we have here.
The shop was just for his window, I made an identical window adapter using a hotknife and a sheet of styrofoam. The rest could just be done with normal flexible tubing and some PC fans...
All you need is a tent, duct, inline fan, board, hole saw, flange, and duct clamps; in fact, you can replace the board, hole saw, and flange with a portable air conditioner window kit, making everything plug and play. Granted, I know my way around a grow room, but this is like a ten minute off the shelf project.
@@hlaw2830 can confirm. This project would cost, what, $200 tops? That's assuming you over engineer the snot out of it like Alex did.
@@helljumper912 Let's see...
>Amazon
>tent: $50 (if light leaks don't matter, we can go cheaper than viviosun, lol)
>4" inline fan: $30 (6" is overkill for such a small tent, like... a lot)
>4" duct with clamps: $10 (clamps > tape, simple as)
>4" flange: $10 (probably cheaper at Home Depot or Lowes)
>4" hole saw: $10 (you can get a set for the same price, but you will throw it away)
I'm gonna say that you need to be a pretty lazy spender to go any deeper than $100 on something like this. For $200 we can add a light, filter, and get the supplies for baby's first autos, might even be able to afford the seeds too.
lol who has all these
Something tells me that just putting a fan in the window would have the same effect. The biggest thermal improvement to the room was creating airflow.
Yes, that's what I thought. He should have compared running the PC inside and outside the tent, but with the fan running the whole time.
my living room has two vents either side of it(trailer), but is almost sweltering because there is no air circulation/airflow.
Fan will help but the heat is still dispersed into the room and a lot of it. With a grow tent, The air is pulled into a confined space and then the heat is directly dumped out the window instead of in the room and then out the window
@@leeroyjenkins0 Yeah, but the tent pulls cool air from the room, which pulls cold air from the rest of the house. You end up creating a negative pressure differential and that causes the home to pull hot air in from outside where there are air leaks in the conditioned space. This is marginally better than just putting a fan in the window, but still less efficient than using a higher flowing vent to compensate for the extra cooling needs, or adding an individual unit for that room whether window, wall, or mini-split. Nothing is free 🤷♂️
@@daqq most places have AC so they're still air coming in. The problem is you have to freeze the rest of the house in order to keep the hot room tolerable. You are correct and negative pressure. So if you're sucking in there that's been cooled and other parts of the house but that's okay
This was interesting. I'd like to see a downscaled version of this. I don't need to move all the heat outside, I just need to move a big chunk of it about 6 feet down the hall where it's cool (in my house). In the summer, the computer under my desk competes with the AC vent under my desk. I wonder if I could fab a baffle of some kind of to vent the top exhaust out of the room.
A compact version? Two blade window fan, one in intake, one on exhaust
Explained in great detail! Thank you so much!!
Those extra struts are used to hang the fan and - if used as a grow tent - lights from. Simply put the fan inside the tent. You will need less space and it will be quieter.
PLANT
@Video Games haha they are quite commonly used for resin 3d printing. Resin produces lots of very unhealthy gases, great to get them out of the room.
You could have quite easily air tighted the PC case itself, all but the intake and one of the 120mm openings on the back, and 3d printed an duct adapter for it. That way the PC fans are pushing the air out, so no need for a large duct-fan, and you wouldn't have any enclosure.
Yes, but that would be the intelligent thing to do. Not an LTT move at all.
yes because a 120mm is gonna be able to push out enough airpressure to push it out the window at the other side of the room?
@@therodyman700 I've actually done a "fresh air intake" kinda thing with some ducting and a 140mm fan, and based on my experiences I'd say "yes".
@@jubuttib intake is different than exhaust.
But then you’ll be damaging the case and other issues they could run into. Plus once u put holes in the case there’s no turning back . This way was perfect
Very interesting project.. I personally would have cut the tent to a smaller size, and then put the fan on the outside of the window so it could run at a higher speed…
Why even use a tent when you can connect the hose straight to the pc case? :)
Brilliant video. I think you're actually on to something and now you need to make your own LTT branded PC cooler tent
3:21 they're used for hanging anything in the tent mostly. light, exhaust...etc
You must grow a lot of tomatoes.
I came here specifically for this comment..good jorb 👌🏻
This is a neat idea. Although anyone doing this should definitely use a duct hood on the outside exhaust, to prevent things from entering your pc. Also there's great tubing options that don't use fiber glass, that stuff is terrible.
The exhaust is exiting at 52.1mph, bruh, nothing's getting in through it.
@@hlaw2830 Pretty sure he's talking about when it's off...duct hood opens when air is flowing out, closes when off.
@@DxBlack They didn't get a thermostat to control the fan, and they're always talking about leaving things running Nice Hash, so... why would if turn off? I don't disagree though, if only because you don't want someone to assume that you're growing and break in, right? Clearly, dryer vent, mount it through the wall down low, boom, cleans up all that ducting for free.
Fiberglass isn’t used in duct anymore. It’s soft white fluffy stuff.
Given the level of custom fab available at LTT, they could just build a sealed case with an exhaust port to fit the ventilation.
That was so helpful! I just started using soft and was so overwheld!
I love the engineering & design heavy videos like this
I simply mounted my motherboard to the wall, horizontal, on top of a fancy piece of butcher block. Then mounted the radiator with two adjustable fans in push push to the wall that hooked onto the 9.99$ lowes "through wall dryer vent". I made a small silencer box and made sure everything was pretty air tight. It made a massive difference in the room and pc temps. It had the flap that closed if pc was turned off. I live in very warm humid climate and I ran it this way for over 2 years with no issues ( moved out ). Since the heat from the pc did not have to travel but a small amount I was able to push it out using very little air flow so it had minimal effect on the whole house . Oh and this was a no case setup it just sat high up on the wall so nothing could be spilled or dropped onto it. Had no issues with dust either.
This is exactly what I want to do one day, glad to hear it works!
Dude you gotta show us exactly how you did it! Did you take any photos? Can you share it please?
this is a much better way of doing what he tried to do. Short tubing runs and an airtight source are the two biggest things, of which he had neither.
Would you mind sharing some pics? I'd like to see how that works.
I've thought about doing this too, perhaps some point in the future
the problem is that if you're pushing air out, air is coming in somewhere so your whole apartment is going to be cooling the warm air from outside all the time. I wonder if the net difference works out over the course of hours or days
Good enough for me, I tried getting a window ac and the fam refused.
They get to suffer now.
LTT, pin this comment
Yeah, i was kind of surprised they weren't pulling air in from the outside to cool the computer. It's only 30-35c outside, compared to a computer that normally runs at 50-60c that's still plenty of cooling capacity.
Yeah, "your whole apartment" would act as a very large thermal battery.
I've just wrote a comment about that. If he used two hoses - intake and exhaust it will work as intended, without creating a negative air pressure. He can also use much smaller turbine, or put it outside to reduce the noise from it.
This was a fun vid to watch, and love seeing the shop tools being used; as don’t have a laser or CNC or 3D printer so fun to see them in action.
You guys sure do come up with very interesting ideas though and it’s fun to see them take shape and work👍🏻
Cheers✌🏻
Just as an fyi for all those ppl thinking that duct tape is used for taping the seams in ducts…..not so correct.
What ya wanna use is silver foil tape, which can also be called mastic foil tape in some areas. That is the tape ya want when taping exhaust ducting to bathroom exhaust fans, other ducting, & other hvacr materials……
Did something kinda similar ages ago by sealing up a case good, putting all the PC fans to intake, installing an ac air hockey table fan on the side, and venting outside via a dryer vent. worked like a champ
This is literally the "we aren't paying to air condition the neighborhood" moment....
Your room got colder because you are punting air out of your apartment at a steady pace!
Yep, you are exhausting cold air out of the room, sucking cool air in from the house. Where do you think the house is getting air from? Its pulling it in somewhere! If your home HVAC keeps up, your power bill will skyrocket!
Exactly, I would like 2 comparison tests, 1. Exhaust the PC back into the house outside the room through a wall vent from the grow tent. 2. Just an exhaust fan towards the top of the room without the tent through the wall. This is for house owners, that can add a hole in the wall. I hope the vent fan would work, if it did then it could be dressed behind a cold air vent return, with the fan inside. Or maybe like a bathroom vent that vents back into the house instead of the ducts, something low noise and nice looking. I would love to see the video on this. My office is 2-5 degrees warmer without a fan in the doorway, I would love the close the door during the day when working from home, but I am unsure the fan/vent would make a low noise difference. Make this video, please.
@@Nate_69420 did you watch the video? He literally says that almost word for word
@@caffeinesippingman that could actually be a good idea exp if you exhaust it into a room that you're not using, on the other side of the house, that you can't shut the vent off in when no one is in there
possibly just an exaust oustide would have done the same job
I wonder if you could 3D print a manifold to come right off of the case. Flow might be more limited, but at least you wouldn’t need a grow tent.
You could literally just ducktape that tube to exhaust fans and call it a day🙈
I actually tried exactly what you are taking about a few weeks ago, you can actually buy premade 120mm fan to 4 inch venting adapters on eBay, I got a powerful DC fan to act as the exhaust but the problem was that the exhaust on the computer isn’t the only place the heat escapes from. I didn’t even think to make a housing for the entire computer. I’m thinking you could easily make a frame out of PVC piping. The actual housing can be any thermal inactive material
@@Prophes0r you could, but then the pc exhaust fans aren't going to be much help in adding extra velocity to evacuate the hot air. You'll be blocking probably 60% of the fan surface. With a manifold you could use those fans to your advantage.
@@DontAskItsNotMe Yeah I was thinking about that. A case isn't air-tight, but I imagine at least a good chunk of the hot air is directed through the exhaust anyway. Did it at least make a noticeable difference?
I'm sure the neighbors love the new inner city look the plywood and hose hanging out the window gives the building.
This is actually a good idea for heat, my room gets to the point where it feels like a sauna after a few hours. I'm curious the type of fan that is and where you got it.
I respect the engineering and DIY attitude that is oozing out of this video, and that you found a solution that works in the end! I'd probably just heavily undervolt the PC during the summer season if the room gets too hot, or simply use an air conditioner to cool it down. You know, like normal people. But that wouldn't make a fun video to watch, so there's that!
In the beginning he mentioned that air conditioner and computer together may trip your breaker, so here is his solution to avoid it.
@@RelakS__ They sell these things called nails in hardware stores, specifically made to stop breaker-tripping behavior from faulty electrical installations.
@@Sup3rman1c This comment hurts my brain XD
@@Sup3rman1c if you like being that cheap, you would love to know, that you won't get a phone bill, for calling the fire department in the USA 😱😱😱
USB C is so amazing now that you could just put your PC in an attic or laundry room and remove the heat source all together. Pretty sure a warm laundry room wouldn't be an inconvenience.
In my opinion a much better design would be to have the tent as sealed as possible with two pipes.
You would still have a fan acting as an exhaust but the one pipe would allow it to draw from the air outside instead of sucking air from inside.
As of right now you are keeping your room cool but simultaneously exhausting out a bunch of your AC too with it meaning much higher power bills, and much higher wear on the AC.
Also probably making your AC much less effective in other rooms around the fan that are having warm air sucked into them constantly (from negative pressure) while the fan is running. As evidenced by the draft under the door.
If you used two pipes (Intake and exhaust) your PC might be getting warmer air into it but that should likely be fine without extreme stress loads.
But in turn you would be wasting a ton less power overall on climate control.
Edit: Another point to be brought up. During the winter if ran like this will also suck out your heat. Which AC is about 3.5x more efficient then resistive electric heating. So that also could be a much much worse scenario.
You want your PC to have cooler air as well. The PC cooling can only do so much if your ambient temperature is very high. Also sucking in outside air has the potential to cause damage to your PC depending on your climate. If you have high humidity or live in a bad air quality area.
I bet some of that would be solved with air filters.
Was thinking the same thing from the start.
One intake one exhaust.
Also like you sad the AC is now working harder so your paying for that in power bill.
And if you dont have an AC this approach is also better if your inside air is cooler then outside, you wont pull hot air in to the building from other vents using a two pipe intake and exhaust solution.
Yeah that's what I was hoping they would do as this seems like it'd use a lot more energy. I feel like you'd only be able to use an in/out system when the outdoor temps are moderate though, i.e. not humid or above 80f. Still a fun project though
@@Catsrules1, I don't think the humidity would be an issue as long as the computer doesn't go sub ambient while running which is really shouldn't under normal circumstances. As that is when condensation would occur.
Logic is that some people live in areas with constant high humidity if not 100% even indoors and their pcs are fine.
The tubes could be angled up a bit before exhausting to make sure that there is no way for rain or such to make it's way back into the tube. But a rain shroud would be good outside too and of course a mesh to keep pest out.
As for pollution I would argue that for a lot of things that may kill a computer like dust, hair and such indoors is probably worse a lot of times.
But still a Filter like you said wouldn't be a bad idea just in case.
As for the heat, unless the day is particularly hot the temperature is probably going to be only 10-20f higher then indoors. At night is might actually be cooler.
Regardless though unless a pc being hit really hard for benchmarks or rendering are likely going to have plenty of headroom to game even if the air it's getting is 90f as long as there is enough airflow to move it out quickly like their exhaust provides. (Many peoples PC probably get that hot inside without good airflow.)
If there live in an area with consistent 100f+ days then I might agree an interior air feed system would be better. But it should be fine tuned to figure out the minimum air exhuast needed to get the PC to run optimally.
Everything past that point is just blowing the AC quite literally out the window.
@, don't forget the extra power from the exhaust itself on top of the AC losses. Double ouch to the wallet instead of what could be just one.
Cool project and I love the Red Green reference.
I love this kind of content, and a perfect time to release the shop jacket. Awesome!
Next project. Install UV LED's in the PC and use the heat to grow pot.
Alex, you are definitely a modern version of Red Green. Your DIY knows no bounds and I love it!

The shop jacket looks amazing
Those poles you asked about in the beginning are to hang a grow light from, or other grow accessories. 😊😊
I knew a guy who swore by growing his weed inside a PC case.
Now we have a guy who swears by using a grow tent to help cool his PC.
We have come full circle.
@@ilovefunnyamv2nd Apparently (and I'm no expert) it will just grow to fill the available space. It makes no difference to yield or potency... plus you can get short bush plants, which helps a bit.
As I said, apparently, because I've never done it myself & I'm no longer in touch with the guy who did it. His argument was that all the airflow, exhaust, and electrical requirements were already part of the case... so why not use it?
It's possible but it would but ditch weed for sure, because weed is very fussy over its growing conditions and generally likes to be kept at a certain temperature with fresh CO2 which... well a PC is never going to provide lul.
@@BenderBendingRodriguezOFFICIAL It's not that fussy really - unless you take it ultra seriously which a lot of people obviously do. But it's a weed at the end of the day. Weeds grow pretty much anywhere they get enough sunlight & soil conditions & the right temperature. Also, he was an IT guy, and I imagine he probably modded his cases a bit. If you're just growing for yourself and not to sell, then you can get away with quite a bit.
@@BenderBendingRodriguezOFFICIAL It's literally called 'weed', that shit will grow pretty much anywhere. Quality will vary based on conditions, but a PC case doesn't sound too unreasonable. If nothing else, it's a funny gimmick.
After Pickle Rick the last thing we needed was Cucumber Linus.
I love love love and appreciate the will it blend reference. I watched that religiously as a kid and it hit me in the nostalgia
Much smaller ones available - for seedlings propagation / cloning and the like...
The downside is, you're just blowing a ton of air conditioned air, yes it's been heated a bit, right outside. If its hotter outside than the warm air from the PC then the air that comes rushing back in will make the whole house hotter. Single hose portable ACs have the same problem. Works if it's not too hot outside, but if it's hot out, your AC bill will go up as the room temp goes down.
50 C is 120 fahrenheit. the chance of temps being HOTTER are extremly low btw. Does not work the same way. Also for their case, they are in canada so i doubt they go above even 90 in summers.
The fact that this system is pulling air in from the rest of the house has me thinking that it would have been easier and more efficient to have some kind of super simple ventilation system that circulates air between the room and the rest of the house.
@@Gene669 I have 4, 8gpu mining rigs all in a grow tent. I vent the hot air up into my heating vents so it flows into the rest of the house in the winter. In the summer I just vent out a window and it works great. No need for anything like AC that someone else mentioned, just a lot of airflow.
@@ObeyThePapaya well yeah but that's temps at the SOURCE. It will drop significantly by the time it reaches the outside of the case, and even more once it travels the 16 feet of tubing he's using. I think the tent and tubing is redundant here, and he would have had similar results by just dumping room air outside and pulling air in from the rest of the space. He's not really disposing of the hot air that well because his grow tent isn't airtight at all, plus he even said how much air he can feel exchanging under his closed door. All he did was increase the circulation through his space by dumping air out a window.
The air gets sucked in also through sewer lines. You will notice the smell quite soon.
Now that Alex has seen that it works, he could easily make his own now. A simple hook and loop door for getting your PC in there and a much smaller design would work really well.
Small ac will work better n less of a Hussel,this just stupid
@@NeVErseeNMeLikEDis much louder, more expensive, and uses 500+w. Exhausting is much more effecient.
@@NeVErseeNMeLikEDis however there are people (like me) that get a headache and a sore throat from most commercial ACs
ITT: People who don't understand that air gets replaced.
That fan is designed for a much larger tent, but it's not designed to cool the tent, it's designed to maintain negative pressure while air recirculates through a carbon filter, eliminating smell. When inline fans are used to evacuate heat, it's typically not from the room, but from sealed HID light fixtures, in hopes of preventing most of that heat from entering the room in the first place... which is what they did here, and where you all get it wrong. If you keep exhausting to atmosphere, your cool interior air will simply be replaced with hot exterior air, which is why those HID fixtures have an exterior air inlet... but that won't work for a computer. It doesn't matter how hot it is outside of your lights are burning at 3,000⁰F, but blowing 100⁰F air on your computer seems like a bad plan. So, yeah, an AC is a much better plan, and that's why we use them, even with air cooled HID lights.
>in b 4 muh swamp cooler
They work great in the green house, but that's a lot of humidity if you ain't in the desert.
@@hlaw2830 last I checked, outside air isn't 50°+ like it is in the case. I have used this form of cooling (negative pressure cooling) in a hot apartment, and as long as it isn't scorching outside, it is definitely worth it. Nobody cares about the specific fan, all that matters is that the waste heat (99.9% of the energy input into any CPU or gpu) is not mixing with ambient air and is instead being evacuated out the building in an efficient manner. A closed off room will get much hotter from a pc than from outside air coming in from another window, or through a vent.
I'm so excited for the shop jacket. Looks amazing!
This is so cool! You guys really make my day!
Technology Connections: "It sucks! Literally!"
At least the portable AC they showed was dual hose type, not just sucking hot air from outside through other cracks like single hose counterparts, or whatever this contraption is supposed to be
Not to mention portable AC are inefficient. Using a good window unit should work just fine.
My thoughts exactly
Yeah and they really aren’t very efficient either
The dual hose are much closer to efficiency of (U-shaped) window unit, the portable they showed even had variable speed compressor, maybe also two separately driven fans?
The midea U shaped window units would be much better around the same price, basically a compact mini split.
However some communities won't even let you mount window units, so something like dual hose portable would actually be a best case scenario for many
I thought TC was just one guy
I must say, I always enjoy Alex's videos, and I would LOVE to see a part 2 of this idea! but instead of putting the whole computer in a tent, build a PC with exhaust directed into a vent/manifold using the same duct work and fan. Heck use one of the Main Gear turbos you have! That would be a perfect candidate, just 3d print a top hat to slip over the top of the case and hook it straight to the duct work for example. Can I PLEASE get a few likes for this idea to come to fruition! =D
I would love to see that as well, although rough calcuation shows that to match even the 280 rad mount on the Turbo, you would need 10" duct
The shop just keeps making me more and more envious. As someone with a background in electronics engineering, but also dabbles in everything from mechanics to wood/metal working I'd probably never leave if I found a way into that room lmao.
Holy cow, I finally have a use for all these used tents. Idk if a 5x5 would be a little to big though.
I'm sure this will get totally lost in the comments, but nice to see someone at LMG actually does grow plants. Looks like Alex has basil, either a corn plant or spineless yucca, and something in those hanging planters outside. I wonder if that helped inspire the idea a bit or helped Alex come across it, mixing the passions of plants and pc's.
Also, that basil should probably get some more light. They can take a ton of light and heat, and in the BC area they can probably take full sun and be totally fine. We grow them in the SW area of USA with no problem, even when it gets to 45 C (though we do aim for some shade when it gets that hot)

A 3D printing enclosure tent would work too! They're smaller so they would probably fit the pc better
@Susanna A quick glance at Amazon shows that the Creality enclosures run right around what he paid for the grow tent (some cost more, some less) depending on the size. Didn't see any 10x the cost? There are, of course, plenty of way to DIY such an enclosure for significantly less (or more) depending on materials and time.
some people use grow tents for 3d printers still. (not arguing, your point is 100% valid) they also can work as a makeshift "clean" room, most supporting the addition of a carbon filter.
@Susanna at some point making a box yourself is more affordable 😅. And you actually get what you want from it
Temp in C, Red Green references...such a refreshingly Canadian video. Thanks :)
I’d love to see this revisited where Alex just designs a cabinet/enclosure for his current PC to go into that has the duct attached right to it. You could even put some heavy duty drawer slides in it to pull the case out for cable management.
might not be allowed for their apartment
13:02 fun fact: ducting is not actually a recommended use case for duct-tape (source: the company). Tremendous editing on this vid, loved it
It is a mix of names, not function.
As already mentioned, you are dumping all the conditioned air out the window at a really fast rate. Your AC will be running constantly now.
My understanding it would be better to dump the hot air from the grow tent back into a larger room of the house and not outside. It's also why you shouldn't dump air into the attic as well.
@@GeoffHellings yes that's true.
@@GeoffHellings I tried doing this with a small fan once. I taped a trash bag around the fan and then stuck the bag under the door to blow air out of the room. It did move some air but it didn't really seem to make a difference.
I think the better solution would be to have the intake ducted to the outside air, that way the PC is completely isolated. It might run a couple degrees hotter, but the saved ac bill is worth it.
Yup. Small win in the computer room, huge loss in the rest of the house. Does he understand that the air being exhausted through the window has to be replaced with that hot outside air via other doors, windows and poor insulation?
That was not the conclusion I expected from the start, but did make sense once you showed the blower you would be using
Alex and David’s chemistry is so good to watch
Yes! We do everything wrong!
Beans
If you truly plan to keep the setup, running the duct along the wall and ceiling will get it out of the way and shorten the route outdoors. Also, you may want to consider a screen between the 3D-printed duct adapter and board/acrylic to prevent insect ingress, especially when the fan is off.
Oh yeah, bugs. Good point! Even on the second floor critters will find their way in, especially on cool days when the hotter air coming out of the house shows up as infrared. They'll home in on little gaps.
deff need to do something about that duct management
An extractor fan like the ones used in a bathroom wired to an outlet with a temp sensor on it would be a much better solution. It would just extract the hot air from the top of the room and draw in cool air from underneath the door. No need for all that bulky stuff and much quieter
@OpenYourMind smarter doesn't make a good LTT video though...
That's what I did and it works great, I think this video was just for fun.
The good part of the grow tent being too big is that you can grow a "plant" next to your pc ready for those extra long gaming sessions

Thanks for commenting and engaging
This was actually a pretty smart idea. theres definitely a way to make this smaller and more efficient and I'm already looking into how to make a smaller more compact version
Great DIY cooling
"this is much cheaper than an air conditioning unit!"
*proceeds to use several tools in a workshop that likely cost tens of thousands of dollars*
buy plexiglass(or wood), cut it to your window dimensions with the hole size for the same PVC plumbing (15,30,45°) pipe which you will connect to your insulated hose.
you can stick velcro on the plexiglass for easy set up/removal on window
you don't need many tools to do this and it costs 30$ total in materials + the tent + 50$ for the motor
TBH its an good idea, but II would put all the hoses up the wall to the ceiling then to window out
no clutter in the room
if you buy spiral duct pipes, then its a lot sturdier and you can go smaller dimension
I use that same type of grow tent as a heated enclosure for my resin 3D printer. Way too cold for resin printing in the Pacific Northwest, but a tent and a small ceramic heater do wonders for my print results.
William Osman shoutout at 11:15, I love it!
My man Alex! I will use this consept with my desk pc.
putting an exhaust fan on the same window, then adding the pc near the exhaust fan will do the same thing without the noise and the bulk.
They are trying to entertain an audience..... obviously........
@@stark0ss712 yes I know, but for people who don't have a laser, a CNC machine, and a 3d printer, plus having to buy a tent that will take up space, that's a good option, I'm not trying to hate, I'm giving suggestions for me and others who will want to go on that option but don't have the budget to do so
@LinusTechTips - I would love to see this become a series. "Making your gaming space cooler" - a series exploring several methods to mitigate the heat produced by gaming PC's. Many of us have felt our gaming spaces become hotter with successive hardware generations increasing power requirements. More-so in light of the jump in the power requirements of GTX4000 RX7000 cards. Revisit the outdoor radiator concept. Dust off the "PC water cooling bong" concept from the mid-2000's. I think everyone is silently sweating out collective a**es off. LTT - only you can deliver us from our swampy hell! 😂
Just put your radiator outside
This was heaps interesting, nice video Alex.
I'm so stoked about the work jacket
I feel like you could DIY a solution for this that's better by putting some (better looking) ducting on the places on your case where the air is exhausting and do the same thing without taking up nearly as much space. It's a neat idea for like a Van or RV PC to dump the heat outside during the summer.
You can't duct every hole the eir is exhausting from, even doing some of them would be 1000x harder, 100x uglier, and waaaay less efficient.
You're better off just getting a smaller tent.
@@cotneit It's too bad that you can easily cut the tent tubes, but you cannot shrink the fabric.
How do you DIY it?
I would put my money where my mouth is, but I am playing TradeWars 2002 right now.
@@drippingwax Yeah, but how do you duct every hole in your case?
I'm not saying you should DIY a grow tent, though you absolutely can "shrink" the fabric by creatively folding it after you cut the tubes to the size.
@@cotneit You can fold it, but what would you do with the zippers?
13:57 The Duct needs to be routed better as the up down and around is killing flow-- Pipe it up to the ceiling and use Command Heavy Duty Strips some large cord/cable hangers to strap to the walls/ceiling and have it reach the exhaust with the shortest run possible either with a 90-degrees horizontal or at a slight decline to prevent rainwater from flowing down into it.
If he stepped down to a 4" duct, he could put a dryer exhaust vent flapper on the outside.
Great implementation and not intrusive at all. Can barely spot the final installation. Both thumbs up! LOL
I have the same tent. Those crossmembers are so you can hang lights and fans.
You should have used the second fitting to make an outside air intake. This is blowing all of the conditioned air from the rest of the house outside.
Why would you want to blow _hot_ outside air on your computer? He just needs a smaller fan, really, that six inch is meant to handle a 1,000 watt HPS lamp burning at 3,000⁰F.
@@hlaw2830 Define hot. They live in Canada. It doesn't get hot enough for the ambient temp to be too high, as long as there is consistant airflow. They definitally shouldnt be blowing conditioned air outside of the house. HUGE waste of energy, as well as warming the house overall and more strain on the AC unit.
@@p0xus Lol, so the elephant in the room is that the three of use are American, and as it turns out, AC is part of American culture. This is the only country where you can assume that someone has AC, and like you said, they're Canadian.
There's literally a video of them installing AC in the old house, a bunch of mini splits. I live in an old run down house in a blue collar town and it was built with five tons on the roof. So, you make a fair point about it not being as hot up North for the most part, but... there's probably no AC to exhaust.
@@hlaw2830 That is a fair point, lol. If there is no AC in the house, than the point is totally invalid. I guess he didn't mention if he had an AC unit or not, did he? I was under the impression that the LMG team knew about not pushing non-saturated, conditioned air outside; so I'm now thinking that he doesnt have a unit and didn't see the need in mentioning that.
The AC unit can likely handle it.
You don't need the whole grow tent thing -- just use a fan to exhaust air out that window, I'd wager it would perform identically, if not better. (Due to no air restriction of that hose and the tent)
Not really though.
As stupid as this is, it's still gonna stop the hot air from leaving the tent. That's a major help.
I actually like this idea quite a bit. It would be cool to make a 120/140mm to 4" dryer vent that could be mounted to your PC and then vented out the window to be less intrusive, definitely would need a powerful PC fan though. You would remove most the heat without losing all the space!
The horizontal bars you were confused by during assembly are included for hanging lights/fans on!
Alex as a Host has really grown own me. Keep these awesome over the top projects coming!
lovely video. it would also be intresting to see what the results are just using the extraction fan on the room without the pc shroud (grow tent) as with that volume of air moving your probably replacing that entire rooms air every minute or 2 :)
With as much air that's being pulled into the room, I'm wondering if just having the blower suck the air from the room and exhaust it outside without use of the grow tent would have been sufficient enough.
In the cooler seasons I just put a window fan in one window exhausting out and crack the other window open a bit. Keeps the room cool and thus cools down the PC
Ya, this is probably a bit more effective, since the PC heat doesn't get mixed with the room air at all, but just sticking an exhaust fan in the window would be a cleaner install and work well enough.
True. It may help with keeping the entire room cool, but that's removing cool air from the rest of the house which means your AC is going to be working harder. Installing a quiet exhaust fan that vents air from the room to the rest of the house might be a better option.
Yes it would have.
hey Alex, have you thought about just covering the outtakes of your case?
like one tube exactly at the 120/140mm fan on the back and an other one hooked to the GPU grid that's on the backside.
i could imagine the default airflow by the fans would be enough to get the job done, if not you could use something like an repeater.. but just for air with fans ^^
would be interesting to see if this smaller version would do any difference, while the PC could suck in cooler air.
You would need an intake from outside as well to not draw in the hot air elsewhere in the house. The same reason monoblock ACs don't work that well. The PC would then be on its own "air loop" and isolated from your cooler inside air. It would run a little hotter because of the outside air temp, but as long as your clocks are stable it doesn't really matter.
Thats fine in this situation as he has central air conditioning. His problem was that room got hot with the door closed and the computer running.
Good questions being answered, as I've wondered about this many times in the hot summer months here in the Midwest, USA.
It gets incredibly hot sometimes with my 30 series GPU running, like sweltering heat hot.
Fr
Don't u have ac?
@@NeVErseeNMeLikEDis most do but like alex said in the video the ac won’t always help in a small room with essentially a heater running
I was playing Forza Horizon 5 with my wife a few weeks ago in my computer room. She pulled out her temperature gun and it was 81f in here, whew! Added to the immersion lol
@@paulmememan508 Meanwhile here the normal room temperature is 93.5 f lol
box fan on the window would make same effect... but LTT, crazy as always
LOL I haven't thought of Red Green since I was a kid!! What a nostalgia trip, used to watch it with pop on the couch way back when
I actually considered something similar using a basic cabinet next to the desk right by the window and vent it outside as well.
That said once I replaced my central AC with a minisplit system it became a non issue as I have temperature control in each room. Had I gone with central air I would have to vent it outside because otherwise to get the office comfortable the rest of the house had to be freezing. I even knew what I was going to use to exhaust air out, you can get a fairly quiet bathroom exhaust fan for about cheap or you can just use a HVAC booster duct fan, put it in a cabinet and run a small vent to the window. You only need about 100ish CFM to keep it cool and could probably do fine with 60CFM.
