Last resort, if you have some boxes somewhere in the house, that have been there for a while already. Empty one out and put whatever is inside somewhere else for now. Somewhere out of the way where it might not be noticed that anything changed, maybe even just put whatever was in there in a different box that you could then put where ever and when it was check regular things would be in it. Use the old box, put the stuff in it to dry. This will not help with the smell, but it could then "be out in the open" in a box that has already been there for a while, so no reason to look in it.
I DO NOT KNOW IF THIS WILL WORK. But, desiccant is the stuff you find in white packets, usually with beef jerky and stuff. It pulls moisture from the air. You can buy the stuff for cheap at walmart or hardware stores. Get some that comes in a bag like the ones you see in food, YOU DO NOT WANT IT TOUCHING THE WEED OR DUSTING IT. It seems to me, only because of your situation, that you could put the stuff in a gallon plastic bag for smell, add a couple of these packets and it would still allow it to dry. This does not allow for air flow, but it should hopefully still allow the moisture to be absorbed and removed from the bags daily, or every other day.
If your in a place that you are not concerned with bringing it along with you, I'd say you could even get away with doing this while it's in your truck...possibly. OR, since it shouldn't be smelling too much through the bag, you may be able to keep it at the before mentioned friends house.
You can get this stuff in a large bag and its "raw" not mini bags, you don't want that stuff. You really want to find the small bags with the humidity holes. Do not let it touch the product. Once again, just to be clear, I don't know if this will work, but I can't think of a reason why it wouldn't. Heat does not make for a good cure, ever. If you just cannot get yourself not to use heat, then remember that THC, cannibinoid, flavanoids and terpenoids evaporate and very different temps. So you WILL be losing stuff if you go over 120 degrees F, that cuts the microwave right out. CBG goes at 120 if I remember correctly, the rest are bit higher, but you want to retain as much of all of these as you can. Bottom line, it wont taste nearly as good, you wont get as much from your product, but if you absolutely have to.....like no other way, oven on warm with a meat therm in it making sure you don't go over 100-110F. I say use a meat therm cause even when I set my oven to 170F for pasteurizing, it still will go over, maybe I have a crappy over, IDK, it's shiny so it must be good right?
I hesitate to even mention the oven as a last resort, but it seems like you might do it no matter what's said, so you might as well know about some of the lower evaporation rates. Doesn't help with the plant material though, that just takes time to break down and mix with the moisture.
