the odor-killing CFLs work great, I use two, but they get HOT ... much hotter than regular CFLs ... I have an infrared thermometer, it reads 165+ degrees F. on their surface, and hotter ... yes, NL99 trains well, clones extremely easily, and is so stable, you can't even force it into 'hermie', I know, I've tried before ... hope you get to smoke some of it, when it's grown like it should be, it will earn your respect, to say the least ... it's dyn-o-mite :dance:
