I do not know how to bend my plants any lower without hurting them, one big cola has already snapped.....is this to close, should I dim my 400w ballast to 75% or 50%?
HPS, to close?

ya thats a little close. i have a air cooled reflector with another fan blowing right under the light between it and the top cola and i can almost have it that close but really dont like to. dimming it MIGHT help but you need to do some LST or something if you cant raise that light

YOu will know when your fans leaves show signs of " light bleaching" your leaves will start to fade to a yellow or they will get yellow and crispy. More common with 1000W HPS I would just keep a eye on the leaves until they show signs of light bleaching.

Take my advice your light is pretty close. Your recieving well over a hundred thousand lumens that close keep it
dimmed to 75 percent you will thank me in the long run.

I had a issue like that and was out of ceiling space, what I did was I went to wal mart and bought some heavy ass fishing weights tied them some string and then put them around my branches it bent them down and worked.

for 400w it doesnt look that close. look at how little penetration to middle and bottom. make your plant grow to where you want it using strings or bending.

I would definitely raise that light up a little if possible. And then add a 2700k CFL on the side aimed at the smaller plant on the side, to make up for it.

Way too close, looks like you might have had it too far at some point as they look skinny like they were reaching. With that said plant looks good but get light away on top and add some cfl or t5s on the side and watch the girl go.

i have 3k in my room with no air cooling. only problem is humidity drops a bunch, plus no loss going through glass is a plus.

if you can not keep your hand above the plant between the light than it is too far.
