No dont even use the puck.
Depending on how long your going to use it.
A day or two the sticks will be fine all by themselves.
After that a water pillow at most will work
Remove the pillow after use.
I left mine out from grilling a few days ago and it rained last night. Then my dog got to it. The RASS inside is still in tip top. I heart the herf a dor.
I echo what everyone else has said. I have a 5 count, 10 count, and 40 count. Love them all. For short trips I don't even bother with humidification. Longer trips, throw in a small bovida.

Iowa ... hmmmm... where at ?
4 days during July... well take a pillow in case. Unless its already real humid out then leave it home.
