Vertical Farming

Forget everything you know about farming. Big open spaces, tractors, even soil. After thousands of years doing things pretty
much the same old way, there’s a, well, growing trend in agriculture: vertical farming. Every green plant needs the same few ingredients
to grow: light, water, carbon dioxide, oxygen, and some assorted nutrients and minerals. Via photosynthesis, plants use light energy
plus water and carbon dioxide to make sugars using chlorophyll and other molecules. They use those sugars along with oxygen to
power their cells. Plants also transform some of the sugars into
other useful carbon-based molecules, like the tough cellulose that gives them structure. The nutrients and minerals are vital to plant
cells staying happy. Nitrogen is used the most. The element is incorporated into amino acids,
which organisms like plants build into proteins and enzymes that make life life. Phosphorous atoms are in ATP, the molecule
cells use for energy. Magnesium is central in chlorophyll. Potassium catalyzes the chemical reactions
that make sugars. So where do plants get all this stuff they
need? In the wild, plants get light from the sun,
water from rain and groundwater, CO2 and oxygen from the air and nutrients and minerals from
dirt. As humans learned to farm we supplemented
some of those ingredients using technology like irrigation or spreading on fertilizers. But vertical farming takes it to a whole new
level, so to speak. Obviously the vertical part is the first step. Everything else stems from that. Instead of growing plants in big horizontal
fields, you grow them in racks stacked on top of each other. Basically do for farming what high rise apartment
buildings did for housing. Growing plants in towers gives you a lot more
production for your footprint. It solves other problems too. Moving plants indoors means they’re not
at the mercy of weather and other environmental factors like say drought or smog. We don’t need to convert more wilderness
to extensive farmland, and it better controls runoff of fertilizers and pesticides into
waterways. Hydroponics is one way to grow plants indoors,
meaning the roots sit in nutrient-rich water. No dirt! As a bonus, that actually reduces water use. One study found that hydroponics produced
more lettuce with 90% less water. There’s also aeroponics, where the roots
get sprayed with a mist of that nutrient-laden water. Aeroponics uses 70 percent less water than
hydroponics. However you need more than water to grow plants
indoors. When it comes to vertical farming the energy
use can be much greater than horizontal farming. Climate control systems including air circulation,
water pumps, and sensors all require electricity. And then there’s lighting. Despite many gardeners’ sunny dispositions,
there isn’t sunlight indoors. How you get this light can make or break the
cost of the whole operation compared to regular farming. Remember, that thar field has a free source
of lighting: the sun. So many vertical farmers use artificial lights. Traditionally, they’d use grow lights, which
produce the full spectrum of visible electromagnetic radiation. It turns out that chlorophyll mostly responds
to two narrow bands of red and blue light, meaning a lot of a grow light’s energy is
wasted. Especially the heat they give off, which can
actually hurt plants. So modern vertical farms often use light emitting
diodes instead. Three things make LEDs great for vertical
farming: One, they give off very little heat. Two, they use WAY less energy than incandescent
or fluorescent bulbs. And three, LEDs can be engineered to put out
very specific colors of light. This means you can dial in LEDs to exactly
the colors that chlorophyll likes best for the plant to grow and flourish. There are already a few companies trying to
make vertical farming work. One uses old bomb shelters in London. Another uses warehouses in Newark, New Jersey,
where they stack plants 36 feet high and carefully monitor all the vital variables to keep the
best growing conditions. [LIST ON SCREEN moisture, carbon dioxide,
nutrients, light, etc.] Right now vertical farming is still more expensive
than conventional agriculture, given that whole free sunlight thing. But there are other advantages to remember. Like using less water. And because vertical farms can be in cities
you burn less fossil fuels to get fresh tasty salad greens to restaurants and grocery stores. So who knows? Maybe a high rise near you will literally
start to blossom, stemming your need to get up so early for those farmers’ markets. Thanks to ChemMatters for their article on

  • It would be nice to see vertical farms become the normal way to farm as then we would have lots of land for animals and also wildlife may retake some of the farming land

  • cover the best concentration (partial pressure) of O2 and CO2 to grow plants indoors or a greenhouse setting.

  • You put the solar panels on the farm land. uh? uh!

  • I have had very little success growing anything other than shade-loving houseplants outside of the ground. In my experience, food plants really like to be in the ground.

  • It would be amazing if our cities were so futuristic that meat, while synthesized from vertical farming veggies, still tastes like meat that we love so much.

  • I can totally see fancy restaurants building something like this in the heart of metropolitan areas to help them get fresher products. But expect the prices to go up for us.

  • What?! The same old way?! Farming today is NOTHING like it was 100 years ago. Nutrients and minerals do NOT come from "dirt", they come from soil, active living soil, with interspecies cation exchange taking place as part of a regulated, tesselated system. That is, unless we decide to force feed them this stuff in salt solution after we've killed off the rhyzosphere.

    The temperate european approach of ploughoing and fertilizing to maintain a monocultureis a relatively recent invention, that has been exported around the world very unsuccessfully from an ecological perspective, and successfully enough from a business perspective (cf. slash and burn agriculture in the tropics, especially palm oil, and soy and corn for beef feedstock).

    This has been augmented with chemicals and mechanization, most notably the nitrogen based fertilizers based on the Haber Bosch process. This only looks good from the lens of an industrialist, or GDP measurements, from any biological or ecological point of view it's pretty obvious the approach is flawed and inefficient.

    Vertical farminmg does not address pests, the energy source, nutrient cycling, or really any other aspect, it's a pharmacy approach to food production, which has been demonstrated repeatedly through recent history to lack the resilience of polycultures.

    It might be the way to produce consistent foods, boutique things, it might even be efficient in an urban setting, but sunlight is free, and an active living soil can do much more for plants than we can hope to with industrial type interventions, at least for the foreseeable future. It might make economic and even ecologic sense in dense cities in light of transportation cost, but this will not supply the billions of city dwellers world with staple foods any time soon, and that goal is dubious at best.

    Furthermore we are nowhere near replacing the complexity of a living soil, and with the extremely low efficiency of photosynthesis (18% at best due to mainly due to limitations in carbon fixation, rubisco evolved in a CO2 rich environment), artificial lighting will always have a huge overhead involved with it, whereas using plants to capture sunlight has many benefits apart from that the energy is free.

  • Really cool vid

  • Did you guys recently get picked up by PBS or is it just something that I didn't notice until now?

  • Why not just going higher, and making kite-like baloon greenhouses?

  • Please make more videos involving flora. Thanks!

  • These have been around for years, people need to start investing

  • When it comes to the excess energy requirements, I wonder how much of that could be offset by placing the equivalent area of solar panels and by requiring less transportation. I could probably find myself a professor or two who'd be able to answer that to be honest.

  • Wouldn't it be possible to have glass roofs and walls that allow daytime light onto the plants? That could cut energy costs by half depending on where you live.

  • A bonus video topic could be about Aquaponics. I would watch that.

  • On the topic of the future of food sources, how about cultured meat?

  • "Of course, some people say it would be vulnerable in a strong wind, but for goodness sake who's to say there's going to be a strong wind?!"

  • In the future we'll just have food facilities. You'll go there, press a button, and hamburger pops out.The bottom 25% of the population won't even know how that happens. They'll think it's magic and form a religion around it.

  • If sunlights a problem why not just make a hybrid greenhouse for indoor crops? That would easily supply the majority of plants until night comes. Marijuan-Tomato farmers will often expose seedlings / vegetative growth phase plants for 18 hours to ensure the fastest possible growth and there would be free energy for around 10-14 hours a day. (depending on the time of year)

  • EXCELLENT VIDEO!!!Shows all the core issues and advantages.I have been doing this for the last 4 years.We have a different vertical farming approach which uses a tower

  • hey nice video

  • Start using SI units please

  • So just solve the energy problem.

    Would solar panels work?
    Plz let me know if there is other alternatives.

  • i have to go to occ tomorow

  • Can you cover these topics:
    1. Ecoblue Water Generators
    2. Magnetic Motors

  • when factoring in the cost of these things, one should factor in the cost of shipping traditionally grown produce into the city. shipping this stuff hundreds of miles is a cost people tend to forget to include.

  • The most obvious advantage is space.

  • Awesome vid…Very explanatory…Thanks.

  • The energy cost for this operation can be completely sustainable with animal power mechanically optimized. Try the "horse speeding vehicle/ animal powered electricity generator".Two horses power (2 x 646 Watts) x 60 seconds x 60 minutes = 5 371 200 Watts per hour with a value of more than 500 dollars equivalency. The claim of using leverage over the gravitational and kinetic energy of animals (ex mass and movement) is free for individual farmers that wanted to build it for with their own resources so it is converted into megawatts for personal use. Your welcome. Two horses power becomes around 500 dollars per hour or more in energy savings.  Build it and it is free for personal use and also a franchise opportunity is also open for commercial purposes to manufacture the equipment and to sale of electricity or its forms such as charging batteries or generating hydrogen on site.  Here it is the video. I figured out something that is much more than a way to entertain the masses. Now I know exactly how easy it is to get people into the business of releasing their own animal energy. We project who we are all the time and our humanity is a beautiful thing. Her it is the other video you were asking for.

  • Solar Panel!

  • This is good project for our food, I produced led grow light for this for more than 11 years, if you need led grow light, you can rely on me. SeeGree produce high quality led grow light . [email protected] skype: alanlong5478, Whatsapp: 0086-13826569119

  • Use solar power panels to generate the electricity needed for the grow rooms. Power problems solved

  • I liked your video

  • I am currently on a project and need your help

  • My topic is TO COPE WITH FOOD PREESURE IN 2025 can u help me with a video on this topic and some ideas

  • Maybe vertical farms can connect solar panels to the LED lights. That way, the sun would be supplying light free light to the plants rather than having the sun's energy wasted.

  • This feels like something in cyberpunk dystopia fictions.

  • Use solar, wind and geomass generators to net zero their energy costs, I think.

  • its doesn't matter if they look the same does they taste the same? i don't think so

  • 1)Talking about a complex system of infinite interactions: soil. And you use the word "dirt".
    2) How many nutrients does a specific plant need and at what quantities?
    3) Maybe the weather is what contributes to the nature of a plant and not a bad thing?

    That's why i hit the dislike button.

  • Still wondering till now why Hydroponic or Aeroponic which usually used by future farm industry always farm lettuces when people doesn't consume lettuce that much, why not put rice to it? Or corn? Or chilli and tomatoes? Why always lettuce?

  • Also, the place doesn’t stink of shit

  • It's a good solution for food security. Try to transfer the technology at grass root level as well should be affordable.

  • Excellent video!) In fact, given the advantages of vertical trusses over classical ones, moving to them is a matter of several years. Personally, I believe that we are very fortunate to witness such revolutionary breakthroughs that change the world for the better before our eyes. For those who do not want to stand aside while others are building the future, now is the right time to take part in creating vertical farms, in work with FARM FRESH HATCHERY.

  • Спасибо.

  • wouldn't it be an advantage to lead daylight through a prism system to get free extra lightning. + will those plants survive normal sunlight 10-20 generations later? + how much energy do those farms need compared to the energy the rooftop can produce if solar cells are on it?

  • Yeah you can grow lettuce but what about potatoes, corn, wheat etc. You have very outdated imformation on farms. Next time compare new up to date farmers. Go big or go home

  • Well why not use sunlight even indoor by engineering the sunlight in through the roof in a way that it would reach every plant by using mirrors

  • wheres the study on hydroponics producing more lettuce with 90% less water? if you didnt cite it, im gonna assume youre talking out of your ass.

  • The puns though.

  • aeroponics, wtf? this is a first

  • Looks great on paper and practical in large cities but too many low information Youtube flunkies see these videos and make stupid malicious comments about farmers on other Youtube videos, especially GMO topics. Look, our poor struggling farmers are financed up to their eyeballs and this is NOT a solution for farms in agricultural areas. Farmers can't pull a million bucks out of their asses to build expensive hydroponics facilities. Maybe a PARTIAL solution in areas hit by severe climate change drought, like the southwest or California. This is ONE solution, not THE solution.

  • Nice video…👍

  • It's good, but try to grow a potatoes with this technology.

  • More trashes than ever I can’t watch anymore

  • I cant download it with subtitle

  • excelent video

  • You can reduce the use of energy if you put small mirrors around the plants, or just use a highly reflective paint. You can maybe even paint all the walls in the room with reflective paint or just white. The entire room doesn't need to be lighted, all the light that goes in all directions in the room is wasted. So, the plants actually use much less light.

    The energy problem is not really a problem as they say, because the sun is up 12-15 hours a day, and the LED light works 24 hours a day.

  • Don’t forget the b12 and mineral Spray lol

  • You forgot to mention, that we need to nail nuclear fusion first, if we want vertical farms to produce anything that has any calories in it. Until that, it's an environmental disaster, using more energy than transporting food from thousands of km-s away.

  • We have developed a solar PVT panel system to cover the running costs of grow lights, pumps and with the byproduct of warm water from cooling the PV panels, keeps the water at 28c

  • A fantastic way to farm… IF YOU USE RENEWABLE ENERGY, SUCH AS SOLAR, TO POWER THE LIGHS. Otherwise, its pointless.

  • I live in New Jersey and I love plants so I’m going to go to Aero Farms or whatever it was called.

  • light doesnt shine well vertically or scale efficientally that way. most commercial growers dont grow that way for reasons

  • Grow at home with this easy guide

  • i still think the sunlight is important.

  • Maybe try redirecting sunlight from the outside to the inside using fiber optic cables.

  • How much does it cost in India for vertical farming in 10000sq.ft.

  • Even as I consider trying this myself, i can't imagine paying for lighting it year round. Natural sunlight is best because nothing we have is nearly as powerful nor has a wide spectrum. Artificial light may be supplementary but unless energy becomes cheaper than dirt & water the farm rules thanks to the sun. Perhaps it will as soil errosion & aquifer depletion reaches a tipping point.

  • Great video! I loved the LED lighting explanation
    But isnt lignin the tough molecule of the structure?
    Cellulose is a long chain of sugars

  • Mirrors can be used for reflecting sun light to the plants

  • vertical farming is the new fashion, but consume lot of energy, if some technology can reflect the sun light from outdoor to indoor without any additional energy consumption that would save some energy cost

  • No faith. Can't we use vertical farming with sunlight? Why not? Is that not economical?

  • Great work
    I like meat
    But I don't take pork

  • You guys should do aquaponics.

  • Don't give the bullshit of costing more. Do it outside and kill the whole energy cost. Most of the energy cost.

  • So now we're using electricity to grow because it's better than the sun and this helps save the planet how?

  • Solar panels will help in the energy side, and people forget how expensive it is to buy land to do normal agriculture.

  • We are going to do Vertical Farming at The Urban Tree Village in Amsterdam 🙂 www.

  • Thnks more information

  • Subscribe my chanel

  • Starting today, at home. Bought €100 of pipes, screws and seeds and have build an indoor 5-level feet wide hydroponics system, completely automated.

  • i love the outstanding quality of this video and all the other videos in this channel. but you guys should rename this video to "Growing Plants In The Air Instead of In The Ground – How is it done?" that provides interest to people who have never heard of vertical farming, like me.

  • The growth of the market could be attributed to the growing urbanization, rising demand for high quality food with no use of pesticides and herbicides, and independent farming technique with low impact of climatic conditions
