I moved my down per the post, so?
I'll keep on, now that I found that guide. It's hard to find any posts on here that will tell ya how far, or close, you can actually get.
Now it's just a matter of my watching for signs of burn as I tune my 600W hps to it's closest safe, and most effective, point by moving it down an inch every couple of days. Slight burn isn't horrible anyway.
