I just read a thread earlier today from subcool trying to grow blueberry and his plants hermied. He blamed it on the breeder and tried pushing his own seeds tga subcool in the thread. He even said he cud have hermied them from too hot of soil so it was most likely stress that caused it and that's not DJ Shorts fault that this 1 grower stressed and hermied there plants. Blueberry is prone to herm under stress. But theres lots of people who grow her and dont stress her and get no seeds. So based off of one persons review he was trying to bash legendary DJ Short on genetics. You can stress any strain to hermie in my opinion. Some just dont deal with stress as good as others.
