Imagine a block of flats with a window box on the first floor. Will the light reaching that box be diminished if someone puts a window box on the 2nd floor?


Yes.
But only when the sun hits a certain elevation

Doesn't the cost of transport increase if you live outside of the city? As the cost of energy increases I see people living closer together and nearer to work/shopping than further away.

I missed this one so my apologies for my late reply.

One of the costs of transport goes up outside of a city, the cost of the energy to go from A to B, the second cost of time goes down as you can travel further much faster due to the lack of population density.

Consider my current job where I have to travel 70 miles each way, each day, and it takes 2.5 hours door to door at a cost of £14 per day, yet getting into the city costs £19.50 per day and takes 3.5 hours door to door. I get a similar amount of money regardless of where my job is but working outside of the city I get an extra hour of family time, travel costs less and my children grow up in the country.

I must remember that investing is a marathon and not a sprint!

Vertical farming will need Aquaponics

Aquaponics - works on any scale from small back yard to large farms

Do some research on photosynthesis and you will understand why the whole concept of vertical farming is in snake-oil territory - much like electric cars as an alternative to oil. Of course the surface area that is cultivated can be increased but the amount of solar radiation in a given area for a given time is fixed. Get it?

As often happens when I post, I come across somewhat harshly - it is just the desire to stop people being duped - those without a basic education, especially in the sciences, are prey to all kinds of schemes which can appear attractive but which can easily be rebutted with some simple maths and common sense.



Every child knows successful gardening requires soil, water, plants and sunlight and that if you are missing any of those ingredients; your efforts are doomed to failure. Every child is wrong.

It may not be possible to replace all four elements as yet, but along with artificial lighting as a replacement for the sun, soil is one more element of gardening we are learning can be successfully omitted under the right circumstances.

Yes, it is possible to grow plants without soil. It is called hydroponic gardening and although it may seem to border on science fiction, it actually works quite well and can be a great deal of fun.

Hydroponics is not a new development. It has been around since nearly the beginning of recorded history. That wonder of the ancient world known as the Hanging Gardens of Babylon was an exercise in hydroponics and rice has been grown hydroponically for centuries.

Today, hydroponics is used in a variety of settings. Wherever soil is unavailable, hydroponic gardening seems to appear. Wildcatters on offshore oilrigs grow their own tomatoes. Cooks on nuclear submarines hydroponically grow vegetables to use in there crew's meals. Right now, plants are growing on orbiting space stations without a single grain of soil.

You see, hydroponic gardening is not simply something at which to marvel at from afar. It can be something you can do at home, as well. You can grow your own plants, fruits, vegetables and flowers hydroponically. [/size]

Hydroponics & Growing Food
by KIM GREENHOUSE on MARCH 10, 2010
in FOOD & WATER,HEALTH & WELLNESS,NUTRITION,SCIENCE & TECHNOLOGY,SOCIAL ISSUES

Paul Brentlinger

Hydroponics is a method of growing plants using mineral nutrient solutions in water, without soil. Terrestrial plants may be grown with their roots in the mineral nutrient solution only, or in an inert medium such as perlite, gravel, or mineral wool. This method of growing crops will become more and more valued as the cost of food rises and as the weather around the world becomes more erratic.
Researchers discovered in the 19th century that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plantís water supply artificially, the plant no longer requires soil to thrive. Almost any terrestrial plant will grow with hydroponics.

We invited Marilyn Brentlinger and her son Paul, the owners of Crop King, a company that has been in business for 27 years, to explain both the wonders and myths of this growing process. Crop King offers controlled environment growing systems and technology for specialty crops including hydroponic vegetables, aquaculture and exotic mushrooms.

QUOTE (nicejim @ Feb 11 2010, 08:05 PM) Each square yard of the earth's surface has a certain amount of soil. Vertical farming changes that. Light only comes from overhead between the tropics yet plants grow outside this zone, with their only source of sunlight coming from the side. The further from the tropics you go, the better vertical farming becomes.

VERTICAL GARDENS are Growing up, suggests SCMP article

"Only way is Up for Vertical Gardens"

East Asia's architects are sprouting new ideas for greening cities, including vegetable gardens on sides of tower blocks.

 

"If plants can grow in the wild on the barren cliff, why not on city buildings too," asks Patrick Blanc, who was a pioneer in installing a vertical garden at the Museum of Science in 1988.  Since then, he has done more green walls in: Berlin, Tokyo, London, Hong Kong, and New York, etc.

 

To house more populations, without consuming agricultural land, cities will have to become denser

 

Sky Green Farms opened in Singapore a year ago, as the world's first commercially viable vertical farm:

 

sky-greens-singapore-worlds-first-vertic

 

+ producing one tonne of leafy green vegetables every day, which are sold in local supermarkets.

+ took the inventor, Jack Ng, three years to develop the prototype for his A-G0-Gro (AGG)

+ vertical vegetable farming using a system of multi-layer troughs, in rotating A-frame structures

+ his plan is to produce 50 per cent of the Sing's green leafy vegetable consumption

+ (this is suitable for stir-fry and soups) : harvested every day, and delivered almost immediately

+ AAG's modular A-frames can also be used on rooftops
