my cap controller (newly purchased, a few months ago) has green lights...

just a thought. I've tried a ton of clones in the last year, and never got a hermie - tho I did get 1 from seed.

I picked up some seeds, and there were some feminized freebies thrown in, which I haven't popped yet. I've been thinking (worried) about what you are talking about, so I'm not negating the possibility... 30% seems high even for genetics.

certainly different strains have different tollerences for different stresses, so all else being equal, I would expect herms to re-appear crop-to-crop due to the right conditions, as much as due to genetics.

I am NO expert, LOL
