Yeah I did the orange peel thing too it works but be careful with citrus peels though they can give a type of mold to the bud that exists in the peel maybe boytris not sure exactly but it can mold your bud What I have found so far to give some taste is a extract I make with glycerin and fruits...this is ok but what I tried last that worked out nice was Floral Waters..the water used to distill essential oils...but if you use try to find pure cause alot of vendors sell with alcohol or preserves inside and they dont say..(look for (msds)if buying online I make some and also buy direct from distillers but these will work if you feed some days before harvest here are some that give good flavor..Neroli(orange flower), Peppermint, Ylang Ylang, sandalwood there are some that I havent tried yet but need to like chamomile has a sweet scent and bay rum for something like diesel or something real dankish..like makin perfume not all of the distillates work good with all buds...also all of the distillates have diff ph's at least most of ya'll have ph meters if not pm me for their ph or if interested Ill try to post their ph's..from pure Floral waters..lastly you can put a piece of cotton with a drop or 2 of essential oils to help with the smell and flavor while curing but just for a short time like a week cause their strong try to let it stay at the top of the glass screw the lid with piece of the cotton in it..again some to try peppermint, davana neroli(expensive), orange, grapefruit, lemon, Bois de rose(rosewood)-maybe..,Clary Sage, ginger, rose geranium and the list goes on..make sure they are pure essential oils and not fragrance oils...all for now
