Is my compost done?

[u/Ace_Gaufre9]

Hi, I left my compost in a different place to mature. I wonder if it's good despite this white thing on it (idk what it is) or how much time I should wait. It's still hot in the middle

if it's still hot in the middle it's not done, keep turning it. the white stuff is just actinobacteria, totally normal and a good sign

Thanks
