but now i was thinking about going 12/12 and having the LED on for 12 and the HPS on for 6 hours...then 12 dark. would that be bad for her?
if you're gonna flower?...you want 12 hours of light and 12 hours TOTAL darkness...every 24 hours...

...not 18/12......OR...are you saying 12 hours LED + HPS for 6 hours at the same time?...followed by 12 hours dark?
