250w HPS Club And Help Guide

Can someone please tell my about how far away to keep my 250 w mh (fan blowing on it) from seedlings. They are in a SH Bubbleponics unit and are just 5 days old. I know about the hand heat test but because these are so young is it okay to use it. I dont want it to far away but I sure dont want to burn them. I had my 250 w hps within 5"-6" at flowering.

if you have yours in a cool tube you can get it real close man. i have mine like 3-4 inches away with no signs of damagebongsmilie

No cool tube as I mentioned. Wondering how close I can get it without one. Some said 12" and that's where I put it last night. No problems with heat this morning when they woke up.

I think I got it figured out now. Try blowing a fan on the light. I use a 12" oscillating fan I blow between the tops & the lights and another 6" fan I point at the tank. My water really heats up without it.

You can see that some of the hair are already going red.... I can't remember this happening before, and I'm worried that I'm gonna be facing problems with root bound. I was afraid of that since I decided to go with those small pots, and now I'm not sure what's exactly happening..... any opinions?

yeah what does that mean if they turn amber early? anyone?:?
 
If they are in pots, just go ahead and transplant them into bigger ones. Just pop them out and replant everything, soil & roots into a bigger pot and put new soil all around and on top of them. They shouldnt even notice.
