When to harvest a male plant

I was wondering since i have one male (im prtty sure its a male) that i should make a little bit of hash out of it.

can someone please tell me when i should harvest it so it doesnt pollinate my female plants? thanks
also can someone verify that its a male plant by looking at the picture i have posted thanks alot for your help

Thats a male and it will pollonate any day.

Just kill it and forget about the hash.

Pull it the second you see it.Take it away from the site gently.You don't want to inadvertently spread pollen.
