    Stupid Humans, how blasphemous you are, and how tragic your Hubris, can't you mortals understand, that you are.. nothing.. without the Gods?…

    Hail APOLLON the Very life giving light of the Sun, the Mighty son, and the very right eye of the Lord of Lords, King of Kings, God of Gods… Infinity itself… ZEUS, DEUS, DIOS!!!

    Those involved in let's say 'alternative farming' have been using red blue LED grow lights in their hydroponics systems for over 10 years. Also NASA studies have shown green light does increase the vigour of the plant growth

    why does the host always have to sound so dumb? why LED but not regular light bulbs? BECAUSE THEY ARE MORE ENERGY EFFICIENT!

    You just know that with planting trays that densely packed, they're using chemically-enhanced soil rather than the natural stuff your everyday homeowner would have.

    You can imagine how useful this will be once they develop a cheaper, greener method of generating huge amounts of renewable energy. For example you could create complexes in the antarctic, drop a fusion reactor in there and create all the food and heat you wanted.

    also when you transition this black vegetation into the sun again will it harm the black vegetation due to its different growth components? it didn't grow that way so it can't adapt into the suns exposures

  • Nerion, Espy Of Wolves 1 month ago

    can you eat black vegetation in this form without green? how safe is this for humans?

    Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture.
