Is there anyway to grow Vegetables without sunlight or power?

[Anonymous]

I was just thinking post apocalyptical way. If you were in a bunker and had to grow food without anything would it be possible?

[BeMuse]

Nope. You need light for photosynthesis. Photosynthesis is the process of changing carbon dioxide and water into glucose (carbohydrates) and oxygen. You can grow plants inside, so long as you have an artificial light source, but you would need an energy source to power those lights. Even organisms like mushrooms that feed on decaying organisms, eventually need light to trigger fruiting bodies to spring up from the mycelium.

Well thats depressing

[BeMuse]

There are organisms that can grow in the dark. They are called chemotrophs. They survive through redox reactions. That said, they aren't what humans would eat and they still require inputs of inorganic reductants and oxygen... No life survives without inputs.

[Asker]

The main thing though is nutrients I would guess. If they give those off it would be fine?

[Asker]

nvm just read the rest

[Asker]

What about wood burning? Would that give off enough light/energy?

[BeMuse]

Some examples of chemoautotroph would be nitrosomonas, iron bacteria, and methanogens.

Nope, wood is not a viable options as a light source. That said there are ways to generate energy underground to power lighting systems... You might want to look into concepts like geothermal power generation via deep wells with turbines or a simpler less efficient technology like pyroelectric generators.

I don't think so, plants use the sunlight for photosynthesis, the process which plants convert carbon dioxide into their food using the energy derived from the sun.
Without the sun they wouldn't grow.

[NotTacocaT6969]

Without sunlight or any electricity there is no hope of growing food.


There would be little hope of not freezing or suffocating to death with no access to sunlight or the surface.

[Smashingdoozy]

Yes. If you had uv lights. I have one on a plant because it doesn't get enough sunlight and the cats keep attacking it so I have to keep it away from them

[NamerOfStars]

Vegetables, no- without sunlight, you need substitutes that require electricity. But with some work, you COULD do certain mushrooms- not sure how edible they are, though.

[Astarlessnightsky]

No, green leafed plants need sunlight to grow.

You may be able to grow fungi in dark conditions, and maybe some algea.

[purplepoppy]

Mushrooms would be possible and so would rhubarb. You could also spout seeds like beansprouts.

[FreyaRed]

I think you slept as biology teacher explain what is photosynthesis

[dustybiker]

Yes. They’ve been growing weed in basements for decades.

[dustybiker]

There is a lot to it. You need proper ventilation too.

[Aakash_Hangargi]

Wow you know lot about weeds 😈

[dustybiker]

@Aakash_Hangargi By my age you’ve picked a thing or two up. 🤓

[slatyb]

They need light, air, water, and trace elements they typically get from soil.

[Agape93]

No. It needs light or a grow lamp. Only thing you can grow in the dark is mushrooms.

[SlothySlob]

Not really a veg, but mushrooms. Damp and dark. The double D's that make the shroom bigger.

[Jenny-Marie]

There are four factors which are necessary for the process of photosynthesis, water, carbon dioxide, sunlight, and chlorophyll. All these enable a plant to grow.

[exitseven]

Plants need sunlight to make photosynthesis happen.

[Anonymous]

use soil, seeds, water and set up violet lights. The question would be how would you power said violet lights because i don't know.

[TacticalLizard]

No better to Accept your impending doom and move on.

[jimmy2]

Yes with certain lights

[Anonymous]

That's impossible.

[chocomilk99]

No smartass

[d3n0939]

Red and blue light

[Anonymous]

Great question
