Humidity Packs - How much do they hold?

[Robermax]

There are no specs on websites that I can find.
Boveda packs weigh around 63.5 grams out of the packet. I assume the Daddario ones are the same but I didn’t think to weigh them when new.
i have a used one which weighs 50 gm and I am leaving it out in a dry room for a few weeks and will re weigh.
Has anyone found this information? Seems it would be useful when rehydrating.

Are Boveda packs any good, and do they work?

according to the little oasis hygrometer i keep with the spanish guitar, humidity has been constant for the past month and a half i have had a pack in; each time i open the case there is a small spike so i guess it works?

I think the Boveda packs work but they have limited capacity each weighs 63-64 gm when new. I am in northeast and very dry and cold in winter. My evaporative humidifier uses gallons per day. I leave a set of humidity packs in each case since water in humidifier runs out at times.
Have Govee monitors in each case and in room.

I like the Boveda, they work well but you need to be in the habit of putting the guitar back in the case when not playing it. Also, if you have a wooden case (not Calton/Hoffee type) they recommend a high-humidifying 'seasonong' packet to treat the case before putting the guitar in

FWIW, Boveda makes the D'Addario packs (disclosed widely?). With a new guitar case, I find the Boveda not keeping up with the dry winter air, so I have sponges, and a bunch of others classical guitar type humidity stuff in my new archtop (wood?) case (Crossrock). My old classical (Calton) fiberglass case is possibly tighter and stays fine with these packs - seemingly almost forever. Packs are supposed to be good for 3 months. But that said, the case makes a difference - both of mine (that I worry about) are middle range ($300-ish). But so does the outside air and the HVAC. I've seen 70% outdoor (winter) humidity paired with 30% inside. We have radiator (hot water) heat and rather than keeping the air moist as you might think, it seems draconian in how dry it is. Drives me nuts. FWIW, I worry less about my solid body guitar.... but tuning shows that the neck definitely deflects with the air moisture (and not).

I use Boveda packs and Govee bluetooth hygrometers in my cases. But as mentioned in this thread, the quality of the case makes a big difference. My "better" airtight cases obviously do a better job of not letting the dry air leach into the case.
