I was smelling one of my friend’s marijuana plants that were in vegetative growth. I ran my hands over the leaves and smelled the aromas that the action produced. The plants that we had already determined to be female had a much more pungent, skunky aroma than the males (which just smelled “green”). Can this be a way to test for plants with an unknown sex? It seems realistic considering that marijauna females have more resin than males.
This is a great observation that deserves further investigation. Even so, many cannabis breeders try to find the most fragrant male to cross with their females to produce potent females for the next crop. Your method would essentially demarcate the females and the most potent and/or resinous males. It would point out bad females and most males in general. This is certainly something many growers would be interested in as a method to pre-sexing. You don’t want to get rid of anything based on smell, but you can mark each plant and then see how accurate you were when they start to flower.
