Liz Bonnin visits a research center in Yorkshire, where they are exploring how plants grow without green light and the potential that it has for farming using technology. Subscribe for more…


  1. I like led it's cheap to buy you save money they are bright they last long they are safe for the environment they also do all sorts of tricks and they don't break as easy as old school style but I still like florescent due to lighting effects that gives off in my aquarium

  2. Blurple is toxic to the eyes, and besides plants do use a little broadspectrum light with green in it.    Whitish pink light is actually the best for plant health and the full nutrition they should be providing for consumption.  That light ratio can be had by simply adding 50% warm white LED.   This spectrum is also pleasant to the eyes.

  3. Umm just from the start there was an incorrect statement. The woman claims that plants use all the visible wavelengths of light, yet scientists and actual common sense says otherwise. It clearly isn't using the green colour that it's at appear as, that's why we see it as green because it is just reflecting that colour.

  4. I looked at the comments expecting to see random people commenting, just trying to get the top comment.
    Instead I'm seeing that, but it's smart stuff!
    Congrats, every knowledgeable person typing away.

  5. My question is how do these plants taste ? Because we know out-of-soil farming exists and can be done but its problem isn't reliability (it needs tons of fertiliser of course) it's taste.

    Since the variety of minerals and nutrients in the plants are way lower, their taste is without history or accident, without flavour or character. Simply put, we can grow a carrot without soil but does it taste like one ?

  6. Since it's a controlled environment, you potentially won't need to use as many pesticides, if any. The ability to use vertical space is also attractive, maybe we could convert old unused missile silos into vertical indoor farms.
