Plants grow better with increased CO2!
More articles tell of the emerging vertical farming industry in the U.S. and the world that in some ways may compete favorably with traditional farming techniques. Vertical farming might not appeal to traditionalists or the self-reliant home gardener, but it may be the way food is grown in the not-so-distant future, and that might not be a bad thing. For those who believe food production will become even more dominated by big business, I suggest learning how to grow food and to harvest and preserve seeds - then share your knowledge with friends.

How Vertical Farming Is Revolutionizing The Way We Grow Food

As Alarcon explained to io9, environmentally-controlled farms like the one implemented by IGES have a number of inherent advantages. Compared to conventional farms (and depending on the exact configuration and technologies used), they’re around 100 times more efficient in terms of their usage of space, 70-90% less reliant on water, with a lower CO2 footprint. Foods are grown without the use of pesticides, they’re nutrient-rich, and free from chemical contaminants. And because they can be built virtually anywhere, CEAs can serve communities where certain foods aren’t normally grown.
Ambient CO2 level in outside air is about 340 ppm by volume. All plants grow well at this level, but as CO2 levels are raised by 1,000 ppm, photosynthesis increases proportionately, resulting in more sugars and carbohydrates available for plant growth.
