i cant remember if it was a CC or hightimes article probably about 6 months ago that they said definately no lps. wrong spectrums and the plants actually tried to grow away from the light since it is a yellow spec. that the plants cant use.
twoguysupnorth Reviewed by twoguysupnorth on . anyone tried LPS? Has anyone tried low pressure sodiums. From what I'e read, the're more efficient than HPS and have a longer life, ballasts aren't cheap though. The light is 1800k. You think that's too low in the spectrum? My flower room is about 2.5'x5' right now, I'm using a 400w hps with 350w of mercury vapor and a shit load of 26w 2700k cfls on the sides. I was gonna put up 2 400MH lights with 3000k bulbs thinking of adding a LPS as well. The 3500k MV lights increased trichrome production. Think that Rating: 5
