I'd used the 62's for a good while even though they were just a bit too moist for smoking. I'm using these 55% packs now and there's a noticeable difference. They're perfect! I still use a 62 pack once my cure has settled in for the long haul though. https://www.amazon.com/Integra-Humidity-Control-Humidiccant-Packet/dp/B01EXCXKBQ/ref=sr_1_1_a_it?ie=UTF8&qid=1472959113&sr=8-1&keywords=55%2Brh
I'd suggest going to Kind Love for flowers. They're on the expensive side, but it's the best store bought I've seen. Lots of places have really poor flower that's machine trimmed, uncured, and crumble to powder dry. These work well to add back just the right amount of moisture https://www.amazon.com/Integra-Humidity-Control-Humidiccant-Packet/dp/B01EXCXKBQ/ref=sr_1_1_a_it?ie=UTF8&qid=1472778323&sr=8-1&keywords=55%2Brh Enjoy your trip.
I get 10 packs of 8g Integra from Amazon (I like the 55%, but 62% is the standard) which I put in all my 2oz jars. It's worth the wait even if you don't have Prime shipping. Your weed will stay fine for the few days you have to wait, but it'll stay fine a lot longer once you add a pack to the jar.
They take a bit longer to stabilize the humidity in the jar but they last a bit longer and are a lot cheaper than the same size Boveda.
