Edit : I was wrong, vertical farming is as ground-surface efficient as horizontal.

"Proof" with a quick calculation for those interested

I compared numbers using batavia lettuce as an example. Those are yearly outputs in kg per square meter of sunlight, assuming central Europe.

For vertical hydroponics, I'm assuming a solar irradiation of 1'000 kWh/m²/year, a panel yield of 20%, and no other loss, that is 200 kWh/year of electric power per m² of solar panel.

1 kg of vertical lettuce needs about 8 kWh to power the lights (https://www.frontiersin.org/...)

So a square meter of solar panel should produce about 25kg of lettuce a year. This compares to 20-50kg/m²/year in horizontal non-light-supplemented hydroponics.

My numbers and assumptions could be quite a bit off, but clearly I was wrong with the 30x comment.

My old comment :

Vertical farming isn't very solarpunk though, it takes about 30m² of solar pannels to grow what could be grown on 1m² using direct sunlight. And I have not mentioned accumulators yet.

In my opinion this is the exact opposite of low-tech energy efficient developpement that solarpunk aims.

I do strongly support urban agriculture, if on roofs, using direct sunlight as energy source, and heated with the lost heat of the building below because that is simple and efficient (I would even call it elegant).

Indeed, as long as it fits this

One criteria for a third place, according to Jeffres et al. (2009), is that it "offers stress relief from the everyday demands of both home and work. It provides the feeling of inclusiveness and belonging associated with participating in a group's social activities, without the rigidity of policy or exclusiveness of club or organization membership".

I don't know for other countries but the Swiss image does not represent the reality. Overcrowded and ageing prisons are a big problem.

Using a salt-water brine you can make lactofermented cucumbers. I heard it was great but i never tried it myself. I guess it's now on my to-do list!

I don't know the specific of your situation, but I would argue against using neem oil preventatively because it repulse pests but also beneficial insects, which weakens the resilience of your plants' environment, making them vulnerable to pests.

That beeing said, yes, rain washes away neem oil. I think direct sunlight should not be a problem if your plant have enough leaves.

Did you use brine or vinegar?

I see what you mean, but depending on the context, having drink alone can lead to unexpected social interactions.

I guess it's also a place where you can meet a friend(s) without the expectations that exist at work and at home. Lacking those places means lacking a space for social activities. What do you think ?

If it's acceptable for your situation, just let them be, and there will be fewer next year.

When a specific weed becomes invasive in an lawn it's because there is an imbalance in the soil. The more you fight, the more you keep the imbalance, which favors the unwanted weed for the following years. Let it proliferate this year and you will recreate a natural balance in which no species dominates.

This is BigSeed propaganda for sure 😂

Store bought hybrid seeds will either be sterile or make bad plants (here they are always labeled "F1" on the bag), and I don't know for GMO seeds, as they are forbidden in my country. But all other seeds should be viable for reproduction in theory.

I've made some of my own seeds, adding new species to my collection each year. I've had easy successes with some species (tomatoes, cucurbitaceae, brassicaceae, most flowers), but no luck with others. I suggest you try and learn what works.

For whatever reason, cross pollination does not seem to be a problem after a few years. I guess it will eventually become one with time if I keep having multiple varieties of the same species. Again, try and learn.

As for storage, I put my seeds in little origami bags made of newspaper, and keep that inside at room temperature. It might not be ideal for conservation but it's easy and works well enough.

Pedantic dude here : I am sorry but the meme is inaccurate. While it is true that André Béguin was a nazi, and also that Wauwilermoos was an absolute nightmare, treatment was not (so) different for allied and axis POW.

POW from both sides were getting warm bath and full meals in the Swiss hotels, so that Switzerland could then send the bill to concerned countries. Only the POW who tried to escape Switzerland and were caught were sent to one of the three internment camps. The goal for Switzerland was really to make other countries pay, to compensate for the loss of the tourism industry.

Those internment camps, especially Wauwilermoos are a shame for the country, but for once Switzerland was indeed neutral.

Could it be a vertical wall of greens? I am imagining a glass building with lettuce behind the south-oriented windows, on each floor. Seems technically complicated but interesting as a though experiment.
