Boveda 58% Two-Way Humidity Control Packs For Storing 1 lb – Size 67 – 12 Pack – Moisture Absorbers for Storage Containers – Humidifier Packs – Individually Wrapped Hydration Packets

Great product and fast shipping

I bought a doz of the Boveda and a dozen of the cheap white ones. The Boveda transfer their moisture to the flower hydrating it in about 3-5 days. The white ones have been in for 3 weeks and the flower is still bone dry and the cheap humidity packs are still heavy and squeshy. After the Boveda packs dry out I put them in a ziplock overnight with damp paper towels and they are recharged with water and good to use over and over.

Increase humidity

So far it's good.

Well they are old and hard so I guess I have to see if the company will honor my purchase and return my money or send a fresh box. We will see. They were not cheep!

I use these for cannabis. They keep the flowers right at that perfect humidity for any kind of long term storage.I half fill an air-tight tote and toss 4 of these in there. You can go back later and can't tell the stuff has been sitting at all. Can't live without them!

We had a particularly cold winter and now a cold spring. I used the 50% humidity packs up to now, and they work well, but am trying the 58% humidity version as replacements since we have extended cold temps here in the North, near Canada. 58% was allowable for guitars, so we’ll see how they work out.

GREAT PRODUCT FOR STORING CANNIBIS
