>>1730084>Keep in mind that it can range from near no cost at all to $10k.If nearing the upper echelons of a hobby is $10k then I'm not fussed.
I buy and restore cars for a living, $10k isn't pocket change, but if it took that much to get to a point where I was producing enough food to sustain me, my family, and a few friends bunking with me, that's fine.
I'd /like/ to do it for cheaper, but if I couldn't then I wouldn't be fussed.
Keep in mind I'm more than happy to buy a bunch of raw LED's off aliexpress, thermal glue them to heat exchangers, and use their thermal energy to keep a biogas generator warm or heat the house or something, all if it saved me a few bucks.
I'd bet I can get where I want for under $5k.
>a polytunnel will help the air and soil inside gain warmth. At night it will help prevent quick heat lossCall me an absolute fucking brainlet but I always thought that it'd be preventing as much heat gain as heat loss?
Now that I say that, during the day you have giant death ball warming it up, and during the night all that's cooling it is passive convection.
Alright ignore me, I'm clearly rarted.
>Add a second layer with a small air gap between the two layers for even better protectionI was gonna ask a question here but we can probably skip that.
>You won't need grow lights in a polytunnel or greenhouse.Interesting, so the only issue here will be warmth then?
>Zone 5>-20 to -10 f minimum tempWell shit then brother, guess I'll be totally fine. Where I am, the lowest recorded minimum is 27f.
>If it never gets below 55F/12.7CNope
>then you can grow pretty much anything you want.My problem here isn't that I can grow anything I want, the problem is narrowing down the selection from "All plants edible by humans" to five or six high-yield crops.
