Review on JellyBeadZ Generic Crystal Hydration Expanding by Jamie Smith

Bought to dampen cigars. I don't think they're exactly 65-72% complete, but if you get by with the right amount of beads and water you can get there. Do not expand them more than halfway, this will keep the humidity at 80+% even with a few lightbulbs in large humidors. One thing is clear: you don't have to put a lot of water in it, and you'll probably have to top it up quite often. I would add a small amount of these beads and a pack or two of Integra Booster or something to even it out. It seems to stay around 68-70% much longer in Southeast weather conditions.
