Curing jar recommendations

I personally buy simple mason jars with wire clamps. They last forever and are absolutely airtight. I prefer the ones with 0.5 and 1-liter volume. They cost around 5 euros here, and you can find them in any discount store. Clean jam jars do their job too 😅. You can get hygrometers on Amazon, for example, with 3 pieces per pack for about 9 euros. And lastly, small osmosis bags. You can find them in grow shops and even at many seed banks. I use the "moisture fighter bags" from Royal Queen Seeds; the large ones cost about 5 euros, and you can reuse them multiple times.
