Well just to add, so far my plants have not shown any herm issues, one has a bad growth structure and a calyxs busting stacking growth pattern ive seen before on some other genetics that's not desirable in my opinion.
But @MadScientist did you actually have fully fledged seeds ? Have any pictures of dissected calyxes ? Reason i ask is sure my plants are displaying swollen calyxes that at first glance to some they would consider them seeded, but they aren't.
Reason why i always check, as ive been fooled to many times.
Said aforementioned swollen calyxes, that are "not" seeded
And the non desirable calyx bursting / stacking genetic trait "personal preference here", where in the end you get a lot of stem in comparison. But something i've seen before
