OK, got it. But to add, is the pollen still good if its not dry yet? In other words the pollen sacs are almost open but 'wet' if you will. So the pollen doesn't show up on the paper. Its all stuck together and not powdery yet. Reason I ask, I'm at day 26 after the switch. Getting a bit close to then end of window? or can I let them dry for another few days until I see pollen on the paper?
