how long does it take male parts to drop pollen

i have one female thats flowering...atleast i thought it was a female, i just knocked some male parts off but they were only on one node, after i knocked them off i couldn't find them, they were just gone, the biggest one was less than 1 cm big, should i be worried or just let it go

...once you see sure signs of sex, you got about a 3-6 week ballpark (depending on strain) before pollen starts to spread.

i disagree. i had one drop pollen 2 weeks from switching over to 12/12 and it ruined my maui wowie crop. i just ignored them for a couple days and bam! pollen everywhere. in one 2g bud i got over 30 seeds, making that 2g bud less than a half gram real quick... i would definately make sure you stay on top of them checking them every day after you put them into flowering and pull them as soon as they start showing the little sacks, it will always be a male if there is a cluster of balls at the nodes and they will usually start to show(although they are fairly small) with in a week on the males
