Ok so i finally bought a 1000w MH/HPS setup. its currently in the mail. Ive been growing for a while now using 650w of CFLs, which was fine for me really, but ive reached the peak of what i can do with them and realized im never going to get the denseness i want in the buds.

My question is how far away from the plants should i hang the 1000w light? My dilemma is its a closet grow, and the section of closet i setup my grow has 2 tiers of wire shelves.



Im thinking im going to have to take down a section of the shelving. Its working good for me up till now because i keep my vegging plants under 6500k on the top shelf and my flowering plants under 2700k CFLs on the bottom. You think if i kept the shelves up it would be a problem? The light should make it through and to the plants, but that just seems silly to me.

So my main question really is how far should i keep the light away from plants, and also if anyone has any tips or advice for HiD lighting please share. Thanks
Depending on what type of HPS your using I would suggest between 18-36 inches.
