IMHO here's how I would do it. I would stay away from using orange peels (or any other peels) becuase of the increased chance of bringing mold to your stash. If you have a small personal amount this shouldn't be as much of a problem. You said you ahve large amounts though, and i wouldn't take chances. To rehydrate your stash you can put in a qtip dipped in water, or buy a cheap cigar humidifier (not the humidor, simpel credo caps will do, about $2)
If you have larger amounts that need to be stored for longer times I'd suggest a few other things. First dry your stuff (if it was wet to start) but not so dry it crumbles. Then if you plan on storing it for over 2 weeks put it in airthigh containers and freeze it. Mason jars work great. Airthight so your stash doesn't dry out and keeps "new" air out, and freeze tokeep it better. Do this because air (ozygen to be more exact) does hurt THC over time. Under a few weeks you should be fine though, just keep it out of sunlight etc.
if your not storing it for that long or dont' have those kinds of amounts just keep it in a baggie or better yet jar.

Sorry I can't help you more then this, i've never actually done the whole freezing down thing, but its what can be found in many a begginer guide. Take care and best ofl luck.
