It’s funny, I’ve had mixed outcomes with “nanners”. My last grow I had a plant that had many nanners and single male flowers sticking out of the buds, happened very early in the flowering process. I figured I’d get a pretty fair amount of seeds on all the plants in the tent, turns out I got 6 seeds all off the plant that nanners/flowers, so I have a feeling that the pollen was mostly sterile. I’ve also had plants that only got a few nanners/flowers and seeded the crap out of the buds, go figure!
