A 4 story farm has 1/4 the sunlight.
Less sunlight grows junk food. The equations are basic and irrefutable.

Cool technology. But as a nation are we not farming less of the land as a percentage while the population goes up and up? There are vast areas where farming was once common where it subsequently became inefficient due to mass farming and easy transportation. So I guess I am asking why this is necessary.

LED is not light.
LED grows poor quality junk food.

A lot of the vegetables in the supermarket come from canada or mexico depending on where you live. it makes much more sense to have greenhouses and vertical farms around major cities so produce is locally produced.
vertical farms use grow lights tuned to frequencies the plants use— not sunlight.
Oh I see - things that cannot be grown outside in our climate.
The US currently imports more vegetables from Canada than it exports. The vegetables that come from canada are all grown in greenhouses. the vegetables that are grown in Mexico often come from farms that are watered from sewage plants.
vegetables that are grown indoors don’t need herbicides and pesticides. they are not subject to the whims of the weather. we’re basically talking about another agricultural revolution on the scale the tractors and railroads that opened up the farms of the midwest in the 1920’s.
“LED is not light.

I grow: Serrano, Jalapeños, Anchos, Swiss Chard and cucumbers year around in my 5’ x 5’ grow box in my basement — all with inexpensive LED lights.
The food is superior to what I can grow outside during my Montana summers, and bug free.

Or produced in California using water they are swiping from the western part of the United States. I like this idea in that it allows the midwest to compete year round for vegetable production. I don’t think it takes away from the normal crop seasons for grains, etc, but it does help make the rest of us more independent of foreign or california growers

You are not the only person who has grown a garden, I assure you.
People eat hard tomatos because they look like food. But a manufacturing chemical process gave the vegetable its color.
People drink HFCS because it is made from corn.
People drink orange juice because it looks orange.
People eat big peaches but they lack nutrient content.
All these make you sicker over the long term.
Please explain to us the physics of EM waves and their spectrum.
People live their lives on LED bulbs but they make hunans sick, depressed and blind. Lacking spectrum also creates inferior plants.
As a matter of fact, there are 54 billion acres of land, enough for every family on Earth to still get 40 acres and a mule. Not all of it is easy to farm, but then the Chinese have rice paddies in the mountains. Nonetheless, the absence of pesticide or fertilizer run-off, the minimal use of water, the ability to be near cities (consumers), etc., is quite something.
And makes those idiot leftists and there bug-eating nonsense look like a bunch of drooling morons.
It all depends on the LEDs. I wouldn’t farm with the ones in my office. The spectrum is skewed. But there are fine LEDs for food.

Humans evolved on full spectrum light from a heat source of the sun or fire wood. LEDs generate no heat and lack spectrum. LEDs are blue limited spectrum. Real light requires a heat source, and higher energy and higher expense.
LEDs CANNOT simulate light. Ever. It is impossible without a heat source.
This is why humans get sick on LED lights.
This is why you get sick long term on LED food.
What part of science are you all missing?? What you don’t know, CAN hurt you.

Absolutely!
China has put cardboard in food.
It looks like food. It has the same color as food.
People eat it.

Your ignorance of basis physics is amusing.
James Clerk Maxwell would be offended by your slanders of science.
