Hmm, I'm surprised you are having issues this early in your season.
I pollinate before work, typically before 8 am. I often use pollen that isn't fluffy & I rarely see any liquid on the stigma.
That being said I have yet to correlate anything with days when I dab & get pods and days when I don't get pods. The general trend is rain & humidity are bad for pollen formation but not always. Some perfect days (low humidity, sunny) nothing takes.
My best advice is to keep trying. Do you have any plants that set tons of pods? I'd try mostly with them first even if they aren't what you want to cross. Try using both fluffy & not fluffy pollen. Try wet & not wet stigmas. Also make sure you aren't stingy with the pollen. I make sure the entire stigma is covered in a thick layer of pollen.
Good luck! I'm sure pods will start setting soon!
