I have been saving the seeds from our bags. We get ours from a grower who does JH and Haze. I can only assume that a hermie got past him a few times.
Anyway, every seed that I have grown (30+) have been female. I have friends who have grown many of them as well with the same results. No hermies, just female. I started 20 seeds this time, 18 of which sprouted within 24 hrs, and I have 10 confirmed females so far, and I pretty much expect that the rest will be female too. Which sucks, 'cuz our grower is now out of biz, and I am almost out of these seeds. I want to continue this line, so I guess I'll have to try and "force" a hermie for pollen.
I have heard a shitload of opinions about this, almost everyone says they are no good, will create more hermies, etc. But in MY limited experience (2nd grow) it's all good!!
I can only assume that they were fertilized by a hermie, since if it was a male that did the deed, I would think that I'd be getting my share of males as well. Thats just not the case.
Just for what it's worth.
