Singapore Builds First Vertical Vegetable Farm

kkleiner writes "Short on arable land? One solution would be to plan up. Singapore, a small country that imports most of its food, has now begun selling vegetables from its first vertical farm. And even while they're more expensive the vegetables are already selling faster than they can be grown. If the farms prove sustainable – both technologically and economically – they could provide a much desired supplement to Singapore's locally grown food and serve as a model for farming in other land-challenged areas."

This term doesn't mean that they're not worth eating; it comes from the fact that peppers like full sun, but many good hot peppers are from small plants that get shaded out in a garden by other, bigger plants. So you grow them in pots that can be put on any sunny level spot, like a porch or patio or window sill. When they get covered with flowers plus green, white, orange, purple and red fruit, they're very decorative. Like sweet peppers, they're edible at any color stage, though the ripest tend to be the hottest. The green or white ones are less hot, but this lets the other non-hot pepper flavors come through.

      One problem in our household is that, due to my wife's allergies to most furry critters, we share the house with three small parrots. Like most birds, they love hot peppers, and strip them off the plants when we're not watching. So when we take the peppers indoors for the winter, we have to put them in a few sunny windows that the birds can't easily access.

      Like tomatoes, peppers like rich soil and lots of water. So give them some compost if you can, don't let them dry out, and you'll have some very pretty, edible crops in a few months. You can use the seeds in any hot pepper that you like, but if you use a store-bought pepper's seeds, you'll have no idea how big the plant will be. So it's better to just ask for a few peppers from someone who's already growing them. Just plant a few of the seeds in each pot, put them in a sunny spot, and keep them watered.

      The Singapore plan only works if there are areas you're happy to cast into shade (and block views from) with these towers. They can't be close together, or they'll be in each other's shade.

      Singapore is almost right at the equator, so if you have a row (or wall) of these towers in north-south orientation then they should not cast much shadows onto one another. And besides most of the sun they catch is the first half of the morning and the second half of the afternoon, as the rest of the day the sun is so high up that you basically don't have sunlight hitting the sides of your towers.

      My objection was that for anything like that you could make work in a sky scraper, you could much more cheaply put the same technology out in rural areas.

      What rural areas of Singapore are you talking about - the ones that are Malaysia or Indonesia?

      As for blocking views, the Singapore skyline already has loads of high rise buildings, so blocking views is hardly a concern. Especially since it is a tiny island nation with a population density that almost rivals New York City.

      To a certain extent, it'd probably be feasible for the existing skyscrapers to be modified to include their own vertical farm for limited self sufficiency, which makes this an even more viable and attractive solution.

      Imagine working in a Manhattan office building, and knowing that not only is the most of the food in your canteen organic, but it's grown in the building, and you happen to have an office that looks out through the flowering fruit and vegetable fields. I, for one, would love that.

    If they can move those towers on just 50W, then there should be a real savings in energy versus trucking the food in from 50km away, never mind from even farther away! Also if you can just rotate the tower during the day to spread the light falling on each plant, you can pick the ripe veggies by hand and save the energy of a tractor or other mechanized picker... Local is fresh, no refrigeration or funky inert gases needed... Plus it provides shade and oxygen. Of course you do spend much energy on making the structure itself, but thats a sunk cost and pollution happening far from the city...

    They should probably go with a more efficient design that uses torches instead of relying on sunlight. It may require a fair amount of cobblestone (or stone if you're feeling fancy) but it is much easier to harvest than their design.

    When I was in the States back in the 1980's I got to know some friends - refugees from Cambodia - and they were growing their veges in vertical farms, on very tiny plots of land - not more than 200 square feet - in the backyard of houses in urban center.
     
    The Cambodian vertical farms are different from the one featured in TFA - the Cambodian version consist of different kinds of veges growing on "towers" made of bamboo.

    In the US we have found that in dense, urban, areas violence tends to be a huge problem. Some cities now use gardens and other methods to encircle a neighborhood such that the neighbors see themselves as a unit and the violence, crime and drug issues decline as a result. Not only vegetables but chickens and fish and other products as well could surround a neighborhood as a perimiter. This boundary would not only define the local turf but it could feed the community as well. And with a policy of hiring workers who live inside the neighborhood it could also take a bite out of poverty. If food is provided as a non-profit co-op the cost of food could also drop far below store prices. As far as sunlight is concerned it can be piped from buildings that need less sunlight to the vegetable gardens. Those roof tops could also house windmills to sell back to the power companies or use on site. I can just see it now. First floor -talapia, second floor- catfish, third floor trout, fourth floor shrimp, fifth floor mussels, sixth and seventh floor fish cleaning and processing, floor eight -vegetables, basement-mushrooms, roof-windmills and solar. Adjaent unit -sales of products.

    Lettuce/tomatoes/potatoes are local, oranges come from California, and other stuff varies, but if you want garlic, ginger, and many other such things you'll have to shop around for some place that sells more domestic product. I found one grocer that sells some nice made-in-Canada Russian Red Garlic. It costs more, but is tastier than the cheap stuff at most stores (kinda spicy), and I don't have to worry as much about it being grown in land full of heavy metals etc.
