Hi 🙋♂️,
You can choose from a variety of options here... from devices from renowned suppliers of grow equipment to some really intense cheap alternatives... it's all a matter of how much effort you want to put in yourself.
If you go for devices from specialized suppliers, you can usually pair them with controllers & thus automatically control the humidity — it's very practical, especially if you want to keep the moisture consistently optimal.
Since you're having trouble with drying, I would recommend just getting a cheap aroma diffuser and setting it up. Just put water in there & leave out the aroma oil… It does its job, turn it on 1-2 times a day & manually track the humidity during the drying period.
Here's an Amazon link (I hope this works)… but you can also find cheaper ones at Action or something like that…
