I prefer the taste of pure herb, so to me its not worth the mold risk. But if you are going to try it, i heard that lime works too.
I have to agree with StickyIcky here..
I too prefer the natural taste of bud. Going about trying to add flavor to the buds, isn't worth the time or effort. You risk ruining the buds.. that you worked so long and hard to grow in the first place.. so.. IMO.. your better off leaving the buds alone man.
But, no matter how many times I tell you, that your better off leaving the bud alone.. your going to do whatever it is your wanting to do.
All I can say is good luck to ya.
Look for my thread about adding flavor/taste to your buds.. its a good thread and a very good read.
peace..
