Note: What I'm about to say isn't from personal experience, it's all from a friend of mine.
Now, my friend (and I, too) LOVES oranges. Like, he'll eat a whole bag of oranges in a day if he can. Loves orange chocolate, orange craisins, orange anything.
He doesn't really grow much, he's done it a few times. He doesn't like the work (he's kinda lazy). On his last grow, as an experiment, he decided that orange flavored bud would be *awesome*. Which would be. Super awesome.
What he claims he did, was this:
He took his freshly harvested bud, put it the bottom of his curing jar, and put some paper towel down, and put half a mostly dehydrated orange on top. And then he let the curing process continue as normal.
According to him, it worked out amazingly, and he ever gets his hands on some fresh bud, he'd do it again.
He claims it works because a mostly dehydrated orange doesn't have enough moisture to evaporate/get moldy and ruin the curing, but isn't so dry that it wouldn't put out orange aroma.
Again, he did this before I ever knew him, so I dunno if it's true or not (but I don't know that he's ever lied to me before). So if anyone decides to try anything similar, don't blame me if something goes terribly wrong.
I've got a crop growing right now, and I'm thinking of trying it out. Probably only try it on 10 grams or so of the whole crop, so if it ends in catastrophe, I won't be ruining my whole crop.
