Dear /sci/

I need nutritional and water collection advice. What would be the minimum set of food items that can be hydroponically grown conveniently (must be nutrient or calorically dense) to sustain a person indefinitely and how many square meters would be needed in the hydroponic setup? Regarding water collection, how big would the fog collector need to be in a really humid zone to collect and filter enough water for a person to drink in one day each day? Any idea where could I find detailed specs?
Thanks in advance.

I'm interested as well, since I suspect this isn't even possible.

Maybe. I was thinking about growing avocado (not hydroponically obviously), kale, peanuts, and beans (and supplement vitamin b12). Maybe add some quinoa into the mix.

>>11576850
I am thinking of eventually implementing and underground panic room too, but not a priority. Saving a little, some kind of underground safe space in a rural location as a backup plan might be possible.

>>11576853
Which obstacles do you think there might be? It might be useful to detect them early on.

I think B12 is a biggie. It's produced by microbacteria in soil, but they need cobalt for that. Using supplements won't cut it, since they're finite and get damaged over time.
Humans produce it in the guts, maybe it's possible to extract it from feces. Ruminants also produce it, but you need cobalt.

To keep the soil fertile, you need to change the crops you're growing every 4 years or so. I'm not sure it's possible to cycle in a way that you always have all important nutrients available this way. Unless the size of your land is enormous.

Then there's also parasites.

I guess your best bet would be potatoes and some legume.
For very long term forget potatoes and everything that is from clones, as clones eventually succumb to disease, so maybe grain except corn (unless you have a source fo alkali to make them digestible; you would soon starve to death otherwise) + any legume (rye is protein complete, but you need a legume anyway as only legumes can get nitrogen from the air) + some fruit (that doesn't depend on cloning, for the same reason as above) or vegetable for the vitamins.
Forget about hydropony though and you're going to need to reuse your urine and feces, otherwise you're going to run out of nutrients very soon.

Avocado is fucking huge. + you will need a carb source, like some grain or starchy tuber.

You could almost survive from spirulina alone. I say almost. It's got nearly complete nutrients and complete protein, but you can't survive off it alone.

Bugs suck. I get worms in my tree. Got a spray that kills them but have to open every single leaf they silk up to get em. Chemicals suck. Will not be using long term treatments. Did not want to use the spray on a fruit bearing tree. Any more naturaul remedies? Probably will kill tree if untreated.

Look up what worm it is and look up what eats it. Some insect predators are commercially available, so you could just buy something that eats it as a remedy.

Maybe I could get a goat or raise some chickens. Regarding soil, only the avocado would require it. The rest would be grown hydroponically. Parasites can be an issue. Maybe they could be prevented by enclosing the hydroponic setup and controlling conditions (could harvest and tend to them in a hazmat suit or some shit)?

>>11576898
I worry about heavy metals and allergic reactions, but it would cover a lot. Maybe I could have other algae that contain b12 (nori?). The dispenser you have shown is pretty great desu. Noted.

>>11576903
Beans would not work as a carb source? Why forget hydroponics? Considering the resources needed for it, is it not volume efficient?

Animals are to recycle waste, which you can compost otherwise and reuse it as fertilizer with no animals. You probably don't want to raise animals just for the meat, you would have to feed them food you could eat yourself otherwise.
You don't have to worry about heavy metals that aren't already present. In fact you really need to make sure all the necessary metals are missing. You probably will need cobalt as well and molybdenum, since plants cannot fix nitrogen without it. Farmers today often just use fertilizer, but you cannot afford that.
Beans do contain carbs, but you wouldn't be able to eat enough to not starve. Beans are to provide amino acids missing from most grains and as a nitrogen source, since most plants cannot get nitrogen from air and you would run out of it sooner or later otherwise. The problem with hydroponics is that it needs a whole industry to supply the nutrients, something that you wouldn't have.

Yeah, but I can stock those nutrients and then transition to soil as the situation demands it (my backyard garden is not that big though). I would also be buying enough food and water to last 2 years approximately.

Do you have some good source to get me the cliff notes to incorporate into the quick guide I am writing (includes as broad categories: water, food, energy, security, medicine/health, communications and misc.)?

Where do you want to grow it? You know you need light, right? A huge, huge amount of light, there is basically no way you wouldn't be able to provide any other way than from sunlight, unless you have a nuclear reactor in your basement and even then I would be worried about the lights or the electronics eventually burning out.

Water is easy. Look up the rain climate, the number in mililiters is the amount in liters you get from one square meter. In a really humid area it will be at least something like 1000l/sguare meter of collector each year and you don't need to water the plants. It is distilled by default, you don't need to worry about filtering it.

Why are you writing a guide if you know nothing about it?

For myself mostly. It is a learning journey and I take notes. Also, I know I need light. I have a place with plenty of light on the top floor of my house (and back in the garden). Regarding water, it almost never rains here, which is why I was thinking on using a fog collector (it is really humid here and could put the fog collector above my house (the filter would be due to air pollution), but not sure about the yield).

It's humid but it never rains? Where do you live, Saudi Arabia?
I really don't know about that. I suppose it depends mostly on how much air you can condense the water from, rather than the collector size, and also that it's going to use energy. You will need massive amounts of water to water the plants, more than it might seem, so this may not even be feasible at all.

In a subtropical desert. Hydroponics is more water-efficient, so that solves the water issue. Avocado does not require that much water if I am not mistaken.

Water will be a problem. Hydroponics will not really help I think, you need a greenhouse.
The issue with avocado is the size. It's enormous, more like a forest tree than your average fruit tree.

My backyard has enough space for it. It has space for another tree too, but that would be about it. The greenhouse could be built on the top floor but will require more modifications than expected.

Fog collectors and a big water reservoir are still my best bets, but doubting the yield and how I would implement the filters exactly. Would like to see some designs.

It's really large though. If you have space for one, you have space for several other fruit trees. And where do you get the water for it?

This is completely unrealistic. I doubt anybody has ever built anything like this. Will your house even be able to carry a greenhouse without collapsing?

You might be better off planting some dry hardy fruits, rather than this.

I thought of avocado due to the fat content, but a couple of smaller trees could yield more calories overall right? I could get the fat I need from peanuts and canned reserves. The third floor of my house did not exist initially. I do think it would be able to carry a greenhouse without collapsing. I already have a gym there and there are several machines there with a lot of weight. Might have to resize it though.

I was tinkering with some vegetables before and realized some vegetables work better together when you cant spray them to get rid of pests, I would do the following:

potato
cabbage -vitamine C
broccoli -vitamine B???
leek
carrots -vitamine K-something?
sunflowers (for chickens?)

potatoes protects the other vegetables from wind, the leek is confusing the flies that eat kale. Then you just need a reliable water source, good draining and fertilizer (preferably from a couple chickens, which will give eggs for protein), I have no clue what area you would need but 50x50 meters is a good start I think

No you don't. You do need some body fat, because some hormones are produced by fat tissue, you don't need to eat fat, it gets produced in the body.

Even the heavily promoted PUFA's are not that important, the only reliably recorded "symptom" of their deficiency is that there is more native PUFA (mead acid) in the body.

Ideally, you have fat in your diet (cause essential fatty acids). Also, there is the point of being more calorically dense gram per gram.
