All of our genetics are feminized, meaning seeds will produce female plants. Our Feminized Seed and the Ethics of Cannabis Farming white paper covers why we do this. That said, there are always a very small percentage (as with all cannabis plants seed or clone) that may grow male parts.
As plants begin to flower, it is important to spend time with them to ensure the highest value crop you can produce and protect those around you from cross pollination. Be on the lookout for plants that exhibit excessively spindly flower formation. These have a higher likelihood of generating hermaphroditic pollen sacs and creating seeds in your crop and your neighbors’.
In our experience, 1 plant out of every 4000 will exhibit either full-blown male phenotypes or hermaphroditic traits in general; however, this is largely mediated by environmental stress.
You will also find occasional plants that produce pollen sacs on the lower nodules. These plants will release pollen when mature and fill your flower with seed. Spray down with water, or place in plastic bag when disposing. Change clothing if contacted with pollen and wash before touching plants again.
Be vigilant on checking your plants, as it is not only your flower that may be damaged by pollen. We walk our fields weekly throughout flower. If you notice others around you are growing male plants, you may consider discussing it with them. Pollen can travel for miles and seeded flower produces lower yields of cannabinoids.
Note the pollen sacs at the base of the node, and full blown male flowers far right.
