  1. i plan to start my first big grow and i can get this monster led hi bay led light for $200 used and online its $325 to 500.

    i already have two dual ended sodium / mh lights to be the main lights.

    would this led be useful in the grow room or is it a waste of 200 bills

  2. Look into cobs or quantum boards.
    What is the size of your grow space?

  3. 18000 LM/150w= 120 lm/W

    you should look for units in the 150-200 lm/W range. this is what the more modern diodes perform at
