That's not a Nanner, its a full on pollen sack. Sometimes MJ will be asexual, and grow fully developed male and female flowers.

Hermi flowers will develop a single pistle and a pollen gland in the same flower, the single pollen gland is the dreaded "Nanner" it's not as much a risk of seeds tho since most of the time the pollen is inactive.

Another sign of potential hermi I've seen is multiple pistles sticking out of a single calax.

Is what I removed in fact a sure tell sign that this is either a male or a hermie? Standing 8 1/2 feet tall, I am sure I will not be able to sucessfully remove the sacs if it is a hermie, so if these are pollen sacs and not something else, this Rating: 5
