-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Hydroponics arent really viable without lots of electricity tho and even solar will be limited by smoke in the upper atmosphere and the power grid will be gone within a few days of nobody maintaining it. The smoke would dissipate and youd be able to grow food normally again within a few years, and until then you'd basically be working as if you were in a colder hardiness zone. You'd have to grow stuff that people north of you would grow normally. Grow plants that do well in shade, and dont mind the cold as much. Scavenge what you can too.

This isn't really true, hydroponics can be done outside and on windowsills using the Kratky method en masse and for very cheap. I have a small wind power setup that adds light near my windowsill. I live in an apartment and have a little spinny thing outside on the porch, the light is indirect for my potatoes so I really needed something extra and had no power outlets nearby. Micro wind setups suck for powering your whole house but are fantastic for powering low power draw lights in low light areas. I'm high up enough and the little spinny thing connects to a battery, seems to be enough to keep my potatoes happy despite the shade.

The best solution for farming in this situation is obviously to set up a bunch of light towers on nuclear, gas, and wind power but who knows how long itd take for people to catch on to that, sensible governments like China would certainly mobilize this sort of thing and ration energy for it. The massive temperature swings would definitely pick up a lot of wind.

Well the issue is that to do hydroponics in a situation like that your not just powering lights your powering a heater to keep them warm. Since even indoors you want have central heating anymore. Thats a lot of energy idk if a mini wind setup can handle that.

Most cold weather, low power, setups require sunlight for warm, like greenhouses, and who knows how well those will work if theres a lot of smoke in the sky.
