  Day 44. Bulk colonization updateAntler Reishi fruiting blocks — 24 days since Spawn to Bulk!The mycelium growth is looking pretty good so far!Here’s a shot from the other side of the bags. One of the bags still has a big gap in colonization, but no worries, that's totally normal at this stage.Exciting update! The fastest bag has already started forming a fruit body — right through the air filter!Even though it’s not fully colonized yet, it’s clearly eager to grow.Starting from today, I have to leave all the bags completely unattended for about 7–10 days while I'm away.Let’s see what surprises they’ll have for me when I get back! ;)
