bud rot

on a couple of buds i got some mold (budrot) in the center of the bud how do i prevent this. i have oscillating fans and my humidity is at 45 my temps stay at 70 - 75

I've heard sulfur burners help keep the mold in check...
Also Ozone generators...ULTRA VIOLET OZONATOR - Air deodorizing & purification - Ozone Environmental Technologies
kill the mold and the smell...

You invested this much... why stop now...
