  there’s no need for relays if you have low voltage

  That’s a good point. Also makes me wonder if those lights will actually make a difference when it comes to plant growth, given the low power.

    Ppl do it with UV LEDs and they claim it works. I never tested it, i’m dried-a-cactus kind of guy.

      Growing plants with LEDs certainly works, I’m just wondering if the power of a USB port is enough
