Can vertical farming become meaningful component to agricultural econ. | Milan Kluko | TEDxMuskegon

I would be interested to learn more as to where you source your nutrients? The true success of a project like this would be most achievable by some form of cycling of the nutrients you sell to your clients. Otherwise, if you are going to source your base nutrients to urban centers for production into food, we may as well continue to simply transport the food to the urban centers.

Hi Mr Milan Kluko. Is it viable in Singapore? Have you reached out to cities in Asia, South East Asia, Singapore?

[@nunobartolo2908]

will be a terrible business too much competition

This sounds like a sales pitch for the the megacorporations who will sell the lights, chemicals and the fixtures needed.

Since my last post I did some research VFs (vertical farms). Lets take what you said and add what you didn't say to get a better picture. Each self is 32 square feet times 4 hight + 128 square feet of growing area. 340 units = 1 acre. It takes the equivalent of five acres of solar panels to power one acre of plants grown under the most efficient lights. To feed a city it will take thousands of acres. To solar power all the VFs needed to feed all the cities Is ridiculous, I used solar panels to give people an idea of how much electricity is needed. Besides much of the VF propaganda says the VFs will be powered with solar panels. That leaves the electric grid. How many electrical generating plants would have to be built to provide all that required energy? Fossil fuel powered generators are major polluters and the fuels are in limited supplies. Dams for hydroelectric generators harm the ecology of the area. Nuclear power plants are worse with their radioactive waste. These are all damaging to the environment. Only plants with high water content and low dry matter are economical to grow in VFs and have a high price tag. Lettuce is 95 percent water. As the amount of dry matter in the food goes up so does the electrical costs go up and the longer it takes; a pound of wheat would have to sell for $100 or more. Lettuce and micro greens from unsubsidized VFs sell for $16 a pound or more. Only chefs and the wealthy can afford them. UFs (urban farms) Can grow more and a greater variety of food outdoors or in small green houses without lights. The yield per acre can match that of VFs at tiny fraction of the cost. Ufs will be capturing CO2 from the air and sequestering it in the ground fighting climate change. VFs don't do that. You say food transparency you know where your food is coming from because you can see it growing. Then you say you are getting ahead of yourself and will come back to it but never do. That is a typical tactic for those who know what they said isn't true and hope it will be forgotten. How is it possible to see where your food is coming from when it is grown in buildings with solid walls and you don't allow tours. Get your story straight. In UFs (urban farms) you can see the food growing and how it is grown; that is food transparency. Food security which is on the list shown and you ignore is best achieved by diversity both in crops grown and the number of people growing them. VFs are not very secure sources of food as they rely on huge amounts of electricity which can fail from natural or manmade causes for long periods. But UFs would not be affected because they are out doors and rely on e sun not electric lights.
