Help! All seedlings dead apart from 1!

[potgoblin]

ok heres the deal i had 11 seedlings all growing well in my grow box, but then as soon as i added another florecent tube they started dropping like flys, my question is could it be the new bulb? iv only got two tube lights in there and theyre not close enough to burn the plants but all of them have shrivelled up and died over the last 2 nights lease help me!!!!! im down to my last plant!!!!!

Extra light should not cause any problems so it must be the extra heat from the new light. What was temp before? What is it now?... Did you make any other changes?
Here's hopin' for the best..

got a feeln your right there stilletto, when i opened up the box with the second light it was a hell of a lot warmer, what i think im going do is move the second light away from the first one and change the reflective material to something more efficient, that should reduce the heat hopefully
