OK, guys, educate me. I was off the online boards since about '99 when the "new technology" was not yet available (or maybe it was and I didn't know). I am still using foam and PG/Water solution and well, has worked great for me for years now.
I have been reading about beads for the past few weeks now and would really like to know the actual maintenance required when using them. I have 2 huge blocks of foam in my 150qt coolerdor and although I have to replenish them once in a blue while, they are low maintenance for the most part and keep the cigars at pretty much perfect balance, much better in fact, than my friends' very expensive custom made humis (they commented on that a number of times).
Question I have is, Save for a hygro, can one tell if beads require addition of water and if they are holding up well? At least with the proper PG/foam setup I know I don't even need to look at the hygro (although I have 2 running). I know I have a crude setup by today's standards (Vinotemps and all), but have been more than happy with how the cigars are smoking.
What are the real benefits? If any.
