  1. hey i hate to ask this because i feel its been asked before. i tried searching but i couldnt actually get a straight answer. how many lumens per plant would you guys recommend? id be growing the mango strain and putting them into flower at about 15-18 inches do to my limited grow space.
  2. I'd think between 6000 and 7000 lumens per plant is a reasonable minimum for an
    enclosed grow.

    I get that figure by estimating that five 23W CFL bulbs totaling 115W would
    produce 6600 lumens. Presuming each CFL was a 23W 6200K bulb emitting 1,320 lumens
    each. We usually say here that 100W minimum per plant is the rule of thumb.
