I hate to say this, but I eventually gave up on this D'Addario system. The pouches became hard as a rock and I was never convinced they were doing their job. I've read all the approaches you guys have been using, I tried this, I tried that but, no clear result. SO !!! ..... not for me.
I don't want to appear as an advocate for the Humidipak system, but I would like to clear up any confusion. The packs do become rock hard once they have dried out, i.e. given out all the water that they originally held. This indicates that they have, in fact been humidifying the case/guitar. One factor is that when the packs are first used with a case/guitar that hasn't been humidified and which is in a dry-ish environment the packs will dry out much quicker than normal - as they have to humidify the inside of the case and guitar. Once they have done that the rate at which they dry out should decrease.
Personally, I recharge the packs before they go hard, on the basis that once they are hard they are no longer doing their job.
By the way, I said "Humidipak system" rather than "D'Addario system" because the current D'Addario soundhole pouch system is totally unsuitable for classical guitars - I use the Boveda guitar pouches.
An example of the effectiveness of the system I've attached a chart showing the RH within the guitar body (the top mauvish line), the ambient RH (the blue line) and the ambient temperature (bottom red line). If you click on the image it will open in a new browser window and be much clearer.
