Vertical farming is pure genius and could easily utilize low power drain led lighting to grow fresh vegetables. A single solar panel of 120 watts with a small bank of 12 volt 30 amphr batteries could run a large enough system to provide food for a dozen people indefinitely utilizing this methodology. Especially if auqaponics is utilized, fish included. One room of your house to set up this system in, never need a supermarket or even an excess of clean water again. Amazing you say?
I say science – time to make it happen!
I for one am looking at investing in lighting and materials to build.
