>>2639676Hard to say without a picture. If you know what to look for, you can usually spot mycelium at day 3-4. But it's not clearly visible and white until around day 5-7.
Here's a germination I recently took transfers from. I added a zigzag to make the streak pattern more evident, marked my cuts and pointed out a bit that concerned me that ended up being mold.
I germinated on the 14th and took transfers on the 22nd. Just over a week. That's from a very fresh print. older prints may take longer to germinate.
