  1. hi there,
    i am growing fresh man, if anyone have more comparison charts between led and hps i will be very thankful, because i'm building the new website and i would like to include that information.

    and i heard about the relation about LED is 4 times HPS is based on... ? lumens? do you have more documentation on that? Because i want to make a comparison chart between each model (lumens, watts, etc) against different HPS models (250W, 400W, 600W, 1000W, normal, agro, etc).

    thanks so much!
