I just feel that until you can consistently create good crop after good crop, whether it's right from the get-go, or after a few lost harvests, or until you can produce the most from a strain, the LITTLE extras really won't make that much of a difference until the elements that have a big difference are tuned. I mean an extra 2k lumen hps bulb thats 60$ vs. a general hps for 20$ you might as well put that 40$ towards *smoke break* good ventilation or better soils, power set ups, sky's the limit, but i know stuff like MH/HPS switchable ballasts are extra $ for such a little boost**, then an extra set of bulbs 'cause you gotta get one mh & one hps to utilize it.

** a little boost, to someone who can product 1lbs, and have it jump to 1.5-2lbs. is worth it, but when you can't even produce that, it's not the light that's the issue... but yesss if money isn't the issue then spoil those babes!
