==Motivation==
As the topic of growing plants, espacially for food purpuses, under artificial circumstances is becoming more and more popular i began feeling more and more uncomfortable with it. As i was not able to tell why i felt like this, i decided to start experimenting in this field myself, to get in touch with the topic the hands-on way. In contrast to most of the experiments that are conducted recently my goal was not to find a more efficient way of planting but just to watch the effects that a really unnatural way of growing plants can have on the plants or on us.
==Concluding Thoughts==
During my trials of growing plants under artificial light or in artificial growth medium I understood, that probably my initial thoughts were right and wrong at the same time. I still feel, that there is some problems in the way plants are grown but they don't derive from the fact that it's unnatural.
===Artificial Light===
Growing plants under artificial light consumes a hole lot of energy, even if you're only lighting a tiny space, as i did. I used 4 1W LEDs that ran for 12 hours a day which equals 48Wh per day. Thats not too much energy, it is about the energy that a human needs to ride his bycicle for half an hour. But as you can see this was only enough to produce 12 really tiny and week sprouts (and some of the energy they used had already been stored in the seeds). according to wikipeda the sun produces roudn about 1367 W/m² which would result in roughly  68 Watts on the area of my growbox. That means on only one hour the sun produced way more energy than my LEDs during 12 hours and that without any effort.
===Artificial Growth medium===
The growth medium that i used was able to give tha plants a base and to provide them with moisture for
