Artificial Sunlight

Has never been invented artificial light for trees and plants Incase our sun is blocked?

The U.S. military experimented with it since the 1950s and even more since we started living in space stations, mainly through the use of hydroponics that can create artificial environments fully enclosed culture products. However, there is no external solution, I know this problem, but the future is something horticultural scientists need to address. So lifeless green sun would die out - but it is not bad at all like most woody plants, most trees, can be in their state of winter hibernation for a year (or perhaps more ) until the sun shines again + seeds remain in the pavement for years until conditions are ripe for growth - if only temporary image is bad, it will mostly recover again.

yes its called ultra-violet (UV). they also put the bulbs tanning bed! So do not panic Mr manering!

Only on a small scale in large greenhouses in Holland that the use of metals and Halici sodium bulbs to grow flowers, etc., but not on a scale large enough to grow food for humanity

Artificial light is often used to grow plants, flowers or fruit at unusual times or in unusual abundance.

To make an artificial sun in light metering everyone is well, I fear, a topic to be explored by science fiction writers of today.

Do you plan to grow something you need to hide from view???

Here is someone who thinks outside the box.
What an imagination ...
Such a need could arise if this black ...
Now, let's see ... Perhaps NASA could reorganize their angle? huge mirror to catch the sunlight and beam it to Earth? Or is it FRY or blind us?
I remember there is an experience of a large mirror in space - but quite what it used a bit of mystery?
