So, this is my only plant and first grow. Since my plant ended up being male, I'm not in a rush to kill it. Instead, I would like to collect the pollen and stud this little boy out in the future. I would, however, like to avoid a pollen explosion in my grow-box. My question is this: given what can be seen in the photo, how much longer should I let my male flower before harvesting him for his pollen? A couple little notes: I have poked the flowers to see if they are ready to spring-open on their own, and they are not. This is the 3rd week of flowering.
