Is this fully colonized

I'm not sure

Looks it but the pic quality doesn’t do much justice.....It’s best to wait 1-2 weeks after it looks fully colonized to let the mycelium “consolidate” the substrate, this lessens the chance of contaminants during fruiting/healthier mycelium and better flush..the cake usually sucks in/shrinks from the glass when its consolidated..I would even wait till you see little pins forming

This hobby is one of patience!!!
