I know it's open for debate, but I disagree with the HPS being better,... perhaps easier on the eye of the beholder, but for vege growth of MJ I wanna say MH is the better spectrum.

HPS rocks for flower because the angle the sunlight hits the plants later in the season,.... it's filtered thru more atmosphere (sun is lower in the sky), and thusly takes on a more red hue.



As for the 1000w being a bit much for seedlings HELL YEAH!!!!! But he's got it 4' away,.... so its a shitload of light, that's right at the edge of comfort for a fresh sprout :jointsmile:
