Potassium Nitrate From My Own Pee

Cody'sLab - 2026-08-22

I process the oxidized urine from my bio filter into (reasonably) pure potassium nitrate crystals. 
I think I’ve improved at this over the years, even though my equipment and supplies haven’t really changed. Hopefully, this one won’t get taken down. Supposedly, the issue with the older video was that I went all the way to gvnp0wder. Still, I share a lot of information here that the government might want to suppress, so get it while you can!

Uses a sock to filter the pee - weird, but probably it is an old, unused sock.
Also one second later: camera shows his bare foot.

@bellowphone - 2026-08-22

Note to self: do not ask Cody if I can borrow a pair of socks.

@styropyro - 2026-08-24

Your yield for processing just 5~10 gallons of pee is actually incredible. It makes me regret ever flushing the toilet.

@12345NOU54321 - 2026-08-23

After all these years, Cody’s commitment to filming one-handed is so endearing. Like, it’s not trying to be overly produced, algorithmically optimized content, it just feels like, “hey, I was doing something cool, and wanted to show you guys”

@PatrickCordaneReeves - 2026-08-24

True, OG YouTube content. Hope he never changes.

@Scot-p1v - 2026-08-24

That’s what it’s always felt like here: that’s why I periodically search for his content. Cody is such a relatable communicator, such an enthusiastic nerd, that I subscribed within minutes of starting the first video of his I ever watched. Definitely a dopamine rush when I see he’s posted

​@GH-jl2td When you've had your sole sliced open by a bottle, had to pull a bit of barbed wire out of it and got bitten by a fucking rat in the grass, you tend to prefer places that do not present those things while barefoot.

@richardelliott9734 - 2026-08-22

the sock as a filter really topped off the chaotic quality of this

@aGFja2Vy - 2026-08-22

And if you look a few seconds later he is bare foot. Was that his active sock?

@beric-x1l - 2026-08-22

yes! this and working without gloves, splashing piss around 😂

@Timsturbs - 2026-08-22

if anything cody is kinda opposit to being chaotic, despite how it looks.

@MrOrionpax - 2026-08-22

Now for that sock does it also need the same treatment coating I give my own socks for the filtration process?

@Nukle0n - 2026-08-22

Light it on fire afterwards to see if it nitrated.

@simonsilence Reddiiiit, I made a Reddit account once to post in a local gossip thread then got recommended a post from /poutinecrimes/ about somebody's roommate's poutine covered in ketchup. Funny, innocuous, light-hearted, hazing heckling humour, right? So I wrote up and posted a comment about how Heinz ketchup is a USDA conspiracy to flavour and lubricate dry, bland mass-produced beef down consumers' throats. Funny, innocuous, light-hearted, hazing heckling humour, right? Next thing my notifications were full of people asking what my "problem is with other people's food choices," I tried explaining to a couple people what banter is and throwing them bones RE what I like, and they all just kept defending putting ketchup on their fucking poutine LMAO. Ugh I bet they pronounce it "poo-teen" lol

@Alondro77 - 2026-08-25

I ferment urine in an anoxic bottle, forming ammonium from nitrates and urea as the anaerobic bugs do their work. It also breaks apart the large porphyrin rings into nice little organic nitrogen bits. Then I pour it straight onto my grass and corn, and dilute it 1 part urine to 5 parts water for leafy green vegetable seedlings.

The results are spectacular. Popcorn goes from seedling to drying cobs in less than 3 months, I get spinach and leaf lettuce with leaves SIX INCHES in diameter, and my grass is lush dark green.

Mix the urine with wood and bone ash, and you get a HYPER-rich fertilizer for all vegetables.

@yannduchnock - 2026-09-05

No, urine contains urea but not nitrate, and decomposition must be done in an aerobic medium so that the oxygen from the air is used by the bacteria to oxidize ammonium into nitrate. This can be done directly in very aerated soil, especially enriched with pulberulent charcoal - it serves as a support for bacteria. In anaerobic environments, ammonium escapes as a gas: this is a well-known problem in agriculture.
It also contains phosphates.
Ash brings potash and phosphates, it is useful for fruiting vegetables but not green vegetables.

@Alondro77 - 2026-09-05

@yannduchnock The anaerobic bugs are doing SOMETHING beneficial. Because the stuff can be poured directly onto grass without harming the grass at all. Instead, the yellowish grass turns a dark green within 3 days and grows like wild! The bugs in my bottles may be neutralizing the pH and breaking down the more harsh components. They're a type of purple bacteria.

@yannduchnock - 2026-09-06

@Alondro77 It would be even better in the presence of oxygen. 🙂

To be fair to Tom, he usually tries to avoid yellow chemistry. Often unsuccessfully.

@Alberto_Travagin - 2026-08-22

8:54 that quick settling is due to the lower concentration of KNO3, that makes for a less dense solution, thus increasing the density difference with the precipitate and allowing it to sink faster.
