How early will a flowering male produce viable pollen?

[c4kedup]

The question is rather self-explanitory but the low down is that I've got about 40 seeds, 10 days into flower. About half are showing distinct sex. I plan to take the boys out tomorrow but I was paranoid that they might have already pollinated the females. that being said, there are no "nanners" as I call them, but how long am I safe? any help is very much appriciated.

how old were they before you put them in? if they were fully mature males can start dropping pollen in 14 days. but you will see all the clusters of sacks well before they open. if u are just doing this to sex you wont have anything to worry about, you well be able to spot all the males way before they start releasing

What if you wanted to save pollen from a male for a small scale breeding experiment but didnt want to ruin all ur girls. take the male out and how long would you need to let it grow before you can harvest viable pollen?
