There is some experimentation on this right now by picking off the flowers. I didn't come up with the idea but I and others are testing it right now. Here's the thread.I dont believe a female autoflowerer can be kept as a mother. In fact, with my limited knowledge, i have concluded there is no successful cloning of autoflowerers. With this type of cannabis I believe the only grow option is to germinate the seeds and grow them out. Even lengthening the daylength doesnt' effect them as they will flower under 24 hrs of light.
