The only fem strain i can recommend is california hashplant from dinafem seeds. The yield wasnt spectacular, but it was herm free, mold free (being harvested in the rain, after three weeks of rain, grown in a very humid area, i'd say that's pretty damn awesome), and had a very nice high. It was relaxing yet didnt knock you out, if you wanted to go to sleep she would help you do so, but if you wanted to stay up she would allow it. It had a very distinct smell, not possible to describe at first, but after a long (very, very long) cure the herb had the faint smell of maple syrup and pine, with just a little bit of skunk. Potent, but not overwhelming.
From what I've read, you should probably avoid dinafems blueberry crosses because theyre supposedly hermie prone. I havent grown any out myself though.
