How long til I can harvest pollen from this guy?

Alright, Marty just showed his balls at the upper growth, I'm going to move him to an isolated area and provide him 12/12, I'm curious about how long I have to keep him alive before I can take some pollen and then kill him.

First pic marty is the guy in the middle, second is kinda fuzzy sorry, those are the balls he just grew.

prob about 3-6 weeks... you'll know when the flowers start opening.

cool, think its alright if i leave it in there for like 10 more days then?
