Although mine are ok i think that my 2 suffered with heat stress cos all the other 6 died and they looked just like the first pictures on the thread ,but as said prev in thread i added a normal 4" household fan just extracting out of the grow room itself and it seems to help, it gets it down about 8 to 10 degs i reckon ,but if it gets to hot i open my roll up door and although i waste light they def didn,t slow down at all.:smokin:
