I'm getting a very small amount of seed in these from hermie. Not surprising all considered. I consider the seeds viable but will definitely produce more hermies.
What is surprising is that one of these clones, 2nd cloning and largest, 4 months or so in a cloning bucket and then transplanted into coco for another 7 weeks, roots established and only showing signs of veg looks like it dropped a seed into the coco. It's got me stuffed what happened but I just pulled a new seedling from its pot.
