Made this 4 wks ago. Have been keeping it open. It’s been very hot and humid where I live, temps well over 30°C with dew points over 21°C and humidity over 70%. Fuzz appeared this week- is it the dreaded mould?
Boiled the rocks, jar and instruments before I put it together. Moss was from a gravel path at work. Just a fun little experiment but hoping I can save it or learn from it!
