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 damageCan 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.
