Water your house plants with natural organic fertilizer for free

What you need is a soda bottle, a measuring cup or scale, a funnel, some water and some urine.

Step 1: Fill the soda with water

Fill a 2 liter soda bottle with water right up to the top of the label. This will give you about 1.7 litters.

People are getting their facts wrong. Direct urine on plants will kill it as it is too strong. The ratio is 1 part urine to 4 parts water once or twice a week only. Too much nitrogen is also bad for plants. All the best.

in the movie "worlds fastest indian" about new zealander "burt munro" who went to usa bonnyville salt flats with an "indian" motorcylce and won the speed record with his bike the actor in the movie about him pees on his lemon tree.well around the roots. i have used diluted pee added water to feed plants and they never died...nitrogen from the urea in pee is good for green leaves ...if you think about the diet of a person or animal you will work out why cat or dog pee can be strong and kill grass....they eat mainly meat lots of uric acid .... m vegetarian..

Where can I find biochar??

[liliamar]

Make it yourself
Dig a hole
Arrange some non-burning cover besides the hole
fill a third of the hole with very hot and fast burning material. Straw, little dry branches etc.
Then put in the thicker wood you wants to make charcoals of
cover it with some fast burning material
fire it
when it burns really hot cover the hole with the not burning layer (if the hole is wide you will need help here) and quench the fire
wait untill it's cold
Filter the coals out of the ash

Ever seen what the grass looks like after your dog pees on it a few times. It dies.

[Mitten]

Why dont you just use household ammonia? Unscented of course.

[aristide202]

That's not so wise. In large scale was done in China as irrigation additive. Ammonia stinks nasty and is almost a deadly toxic alkaline. You can drink urine, best not to, but you cannot drink ammonia unless you are badly insane.

[Tool Using Animal]

Pee is free! Free the pee!

[All Damsel, No Distress]

HELLO? URINE WILL BURN YOUR PLANTS AND KILL THEM, THERE IS A REASON YOUR BODY EXPELLED THE PEE, DON'T TRY THIS!

[aristide202]

and what about dogs in a rainy ? May be it could be safe.

[diy_bloke]

ones body also expells faeces. Still plants grow on it. The fact that it is expelled by the one, doesn't mean it is bad for th eother

[Moralito]

Apparently you've drunk too much urine and your brain fried. That is simply impossible. Urea is one of the best forms of nitrogenates to nourish a plant. We expel it because our metabolism digests...the plants reconstitute...are able of fixing nitrogen as protein.

[aristide202]

yeah, that's a good answer ! Anyway excess of salt is expelled by kidney and that may be not so good on a long period in a dry climate for some plants, so don't
eat too salty. I never seen someone salting a garden.

[Tidnull]

Our bodies expel what they do not need. This includes excess vitamins and minerals. Who says the surplus nutrients cannot be of use to another being? Do you have a reason why urine would kill plants?

[sdavies]

There seems to be some confusion about pee. Yes, it contains nitrogen-rich urea, vitamins, and minerals that are great for plants. Urine also where the excess protons in your body get dumped. So this "burned" affect your seeing is probably the plant's reaction to the decreased pH levels in the soil. Although, if you're drinking enough water this should not be a major issue.

Of course everyone's pee is different. The content of your urine is dependent on your diet, metabolism, and water intake.

Hope this was helpful!

[All Damsel, No Distress]

Ever had a dog who would pee in the same spot every time? You'd get a burned spot on your grass. And most disgusting, my male room mate burned up my plants on either side of my front door. The reason, so if his dogs got out they'd find way home. It's tough living with a guy!

[A good name]

You're dead wrong. Dog urine is different from human. We take in different things then they do. Urine in flower gardens and such are fine, but I wouldn't do it on food. Plus if it's a little diluted then it definetly won't do any damage.

[2high]

*Pee is full of urea

[Narlo11]

Urine actually is not that high in urea. Most of it is water. The amount of urea is about 2%.

Works wonderfully on Cannabis. The female plant is greedy on nitrogen. More nitrogen = stronger and healthier buds.

[EMich]

A lot of people who grow Cannabis have medical problems IE: medical marijuana. Just a word of Caution. If you are taking prescription drugs. What your body doesn't use will be passed in urine. Especially blood thinners,cholesterol meds, Valium type drugs etc. Everything in the soil will be taken into the plant, making urine poor choice for anything consumable.
On a side note. urine on top of your grass compost will heat it up and 1/2 the time your compost will be ready. Again same caution on meds in the body. The compost can really concentrate after time.

[LiquidLightning]

The female Cannabis plant requires large amounts of nitrogen only in the vegetative stage, in the flowering stage, they need Phosphorous, Potassium, and only small amounts of nitrogen.

[theberrypatch]

There are ne laws comming out that farmers will have to abide by called GAP's, General Agricultural Practices. In these guidlines, any said farm laborer must have a bathroom facility within such a distance according to the farms size. It is not acceptable to urinate on produce and such because of all the outbreaks of salimenilla and disease. Urine is supposed to be sterile, in some cases it isn't though, if you have a urinary tract infection, nd how would an employer know if that were the case. But, if you are just using urine on your houseplants, what is the harm. America can't take away all of our rights! However, I don't agree that any farm can put anything, especially human waste on our food products. That is disgusting because you don't know where people have been! LOL

[diy_bloke]

Recently th ePark Service in London came with the idea that their male staff would not use the toilet anymore but pee outside coz it was thought to be good for the plants.

Could not find that link anymore, but the National trust says the same:

[doitagainman]

Must be male pee not female.....pee. Female urine contains too much acid...

[superMacaroni]

I have a male cat. Would that work?

[superMacaroni]

I feel sorry for you.

[atlantica]

I'm cringing thinking about the direction this is heading. One of you is going to do an instructable about connecting strings and lines to granddad's colostomy bag ..aren't you? Theres going to be a whole thing about Colostomy bags being nature friendly, and you are going to talk about "harvesting stuff," and how it's going to help the earth because everyone is going to want a senior shut-in to keep tied up in the garden. It'll be trendy to have one.. Tommy Hilfiger and Calvin Klein will go to war over the latest pattern for the Colostomy bag..... "There was a time when a colostomy bag was a hidden secret..... no more!! No with nine new shades and 10 bold patterns to choose from , Louis Vuitton makes a statement. I'm not incontinent, I just love my environment !! Plus my tomatoes taste amazing !" And it'll be good for the seniors to too, because they will have human contact....Aww. Here it comes...the ultimate Instructable........ Build a Solar powered Colostomy bag worm farm with poop discombobulator and a pee harvesting processing alchohal STILL for your own elderlyberry whisky and plant fertilizer which is completely non toxic and environmentally friendly!

[Kiteman]

Is it really necessary to be so exacting with the dilution?

I can see that dilution would help reduce the odour, but the concentration of urine varies wildly from person to person and even from pee to pee, depending on how much you've been drinking and eating, what you've been eating and drinking and even on the time of day.

Wouldn't it be as useful to say "mix one part urine and six parts water in a 2 litre soda bottle, water as required"?

[uglybagofmostlywater]

I've read where some people use a 50-50 solution but since your urine might be super concentrated, especially if you eat peanut butter, the idea is that no matter how concentrated a 15% solution will not kill you geraniums. To be really, really safe and accurate you can use a hydrometer. A hydrometer will measure the density of the urine. Does everybody know how to make a hydrometer?

[Kiteman]

(Puts hand up)

Me, sir, I do sir ...

_{... darn, that means I have to write it up, don't I?}

[uglybagofmostlywater]

Yeah, that means you have now obligated yourself to write the instructable on how to make a hydrometer...

[Patrik]

Me, sir, me too! But Kiteman was first, so *he* has to write it up. :-P

Making on is easy - all you really need is a thin straw, some glue, a bit of sand and a marker. The harder part is calibrating it correctly, and keeping it calibrated over time and with varying temperature.

[Tool Using Animal]

Yea, way to much measuring, here's a short cut, if you have a compost pile, just pee straight on to that.

[watermelon]

How do you water houseplants with a compost pile...?

[Tool Using Animal]

you plant in the enriched compost an water with water.

[Tidnull]

you can also plant straight into a compost pile. there's a lasagna gardening instructable somewhere on here.

[watermelon]

Okay to plant in the compost the compost must be removed from the compost pile and put in a pot for the plant. That means you only have a single enrichment if you just pee in the pile of compost. This way enrichment is constant especially if you use the recently published method of potting house plants in a plastic bottle with a string feeding urine up through the cap to the houseplant.

[iPodGuy]

"This way enrichment is constant especially if you use the recently published method of potting house plants in a plastic bottle with a string feeding urine up through the cap to the houseplant." Ha! Why didn't I think of that?

[Tool Using Animal]

you're really giving this too much thought ;-)
