I emailed Heartfelf and the reply was that you can pour small amounts of water diretly on the tube, through the end by taking the cap off, or put the tube next to a bowl of distilled water and let the tube absorb the vapor. I just ordered a Savoy humidor, so I think I'll go ahead and prep the humidor by wetting the wood and placing a bowl of distilled water in the humidor and let it sit for a few days, then add the tube in the humidor and let it absorb what is left of the bowl containing distilled water. I'll post results if anyone is interested.
