Just getting my holiday trailer humidor set up and i usually just use 2 boveda packs 65% but got it started with one of the foam humidifiers that came with it.
Question i thought of is if i keep the foam one charged up will the packs last longer? should i do that for both my humidors in my house to?
I know the Boveda website says not to but is that just so they keep selling more?
The Bovedas are they way to go. If combined with the foam they will always be trying to balance out the RH based on the moisture of the foam. If the foam is too wet the Bovedas will over compensate and try to take in all the extra moisture and at one point be at capacity and cannot take more in, like wise if the foam is dry it will try to suck up the RH and dray out the Bovedas quicker.
Depending on the size of the humidor you can add another Boveda pack, this would also help them last longer. There's no such thing as having too many, they will all work together unlike the sponge.
The Boveda packs can also be recharged when they dry out. Just put them in a small airtight container(Tupperware) with some distilled water in a smaller dish. You can put them directly in distilled water but the paper will breakdown faster. Often I'll spritz them with some distilled water to speed the process a bit. I have a few extra Boveda so I can recharge a few and still have a few in my humidors.
