Vegan Spinach Pie, or How To Turn Your Urine into an Ideal Hydroponic Solution for Plants!

Step 4 Build some kind of system to process your urine, urinate, sleep, and make kimchi.

Your system could be as simple as a 5-gallon bucket hydroponic garden containing substrate with lots of surface area and lots of nitrobacter and nitrosomas bacteria. Here's what my system looked like. In about a month or two, you'll have cabbage to make kimchi or sauerkraut.

What the? Do you really have that little bladder control? Seriously, you gotta sleep right there? Otherwise quite an interesting idea though.

wait a second, what the hell?

This reminds me of aquaponics. Where you grow tilapia fish they eat algae then You use their waste to fertilize plants.  Very interesting art project to show how a fairly simple closed system can create food in a very small footprint.  Next step add effective micro-organisms (or EM) and bokashi to a composting toilet and close the waste loop!.  Well Done!  I'd love to see an instructable with more detail on the construction of the filtration system.

 hmm. just noticed the little cabbages. I can't imagine they are happy growing indoors in what looks like a hospital room. Now I really do want to know what the brix % was / is on them...not that that's the whole story...

This will sound bizarre I'm sure, but this experiment and the way it is being carried out makes me think the author must have been bonded to machines at birth. (maybe born premature) That's the only way I can make sense of such a curiously dehumanized environment for producing something that reasonably, seems aimed at wholeness.

in terms of the kimchee part, there's a lot missing in this instructable.

and I'm wondering about your veg. boullion powder. and your oil. (and the frozen spinach) Maybe some hidden msg in there, and so on... not so great for the urine, et al. But if you are aiming at creating an audience for the follow -up, ( and a buzz around the title) it's really good work. * * * * *

totally bizarre.

but like the dentist in Little Shop of Horrors, it has a certain level of humour.

you're kidding about the bed-setup though, right?


"and served the kimchi to the public. " lol


on a more serious note--what about non-protien nitrogen? aka "funny protein"?

Most (fruit and veg) produce these days has too much of that, even the organic. It's a complex subject but goes to the very heart of the sense of (urine containing) the ideal nutrients to grow plants but not in the right concentrations.
You sound like you'd be interested in refractometers, maybe own one, to measure the brix of your cabbages, as well as your spinach, etc. etc.

funny protein is a huge piece of the pH puzzle, and the pH puzzle is a big part of the picture of health. How did "the public" like your kimchee? I like to make my own, privately.

where can I get nitrobacter and nitrosomas?

[djsc]

I have found a concentrate in aquarium shops that is a combo of bacteria to make nitrites and then nitrates from the fish waste in an aquarium filter. fish waste=ammonia= pee.(approximately). The introduction of the bacterial culture is not strictly neccessary as it will form on its own over time in a well designed filter.
