I would kill to have two 400 watt'ers....for flowering. But, first you got to get though this tricky veg cycle. You say, "old style" 400 watt lights?...magnetic ballasts?...if so...I think, they are better, more dependable that digital ballasts. CMH bulbs work great in magnetic ballasts.

...anyways...the Uv rays from MH's are tricky...watch for leaf burn. I found it's better to "offset' plants some, under the light. Seedlings are very, very tender. And rotate plants, too. (but, not with the light on, I burned my knuckles doing that...)
Magnetic yup, that's dem.
I did see some burn early on, thought it was temps, but that's good to konw too about the spectrum itself, what you are saying makes me feel better about not having the lights "all over them" like I wanted to initially! That would explain some issues I had during my last run. I kept thinking to myself, "how the hell is this happening," my temps were spot on, but I had both the 400 watt lamps in a 4x4x8 tent, so there was no escape!!! Might explain why this run so far is going significantly better than the last too! Good! I love it when I accidentally do stuff that is good! As for the knuckle burning, been there, been doing that! I just accepted it as part of the process, just like bass thumb from a productive day of fishing! It is better now though, I did start rotating the dim side of the table, took me a handful of ouchs, but I am not exactly the sharpest tack in the box some times.

Love your album BTW! You hardly ever see anyone put anything in the pics to give a reference/perspective on size. Surely you have gone through that by now and are on to something new! I won't ask, I know your policy! Whatever you are doing, I hope it turns out just as good or better than the last batch! That looked great!:thumbsup::thumbsup::thumbsup: I hope I get as lucky as you did with my female to male ratio!
