This is what I do (and did). It seems to me KL with no water will give me a RH of 62%. BTW I use an aquarium filter bag to hold mine for a wineador and use 2 tubos as you did in my 70 count humidor. If you need to raise the RH for your preference, spray distilled water (2 or 3 squirts) and then shut your door. This will raise the RH. Then go from there, squirt a little more several hours later if you want it higher or leave it if it is at a suitable RH for you. It holds at that RH very well but if you notice the RH dropping then give it a couple more squirts.

This may not be as precise as the Oasis method but is suitable for my purposes.
I was told not to pour water on the KL as it would wash away the salt thus limiting its effectiveness but can't verify how true this statement is.

Either way use it or don't use it. Whatever your comfort zone tells you. It has always worked well for me and I have no plans to use any other method besides the odd Boveda pack for a traveldor.

Cheers....
