Hermaphrodite pollen is used on non-herm females to produce feminised seeds.

Ideally, the hermaphrodite should be a female that is very resistant to producing male flowers (and must be induced to do so), in order that the a strong herm tendency is not passed on.

Naturally occurring hermaphrodites pollinating themselves or another herm would produce seeds that were almost certain to tuen hermaphrodite.

Generally favourable conditions may slightly boost the ratio of females. Warm (but not hot) general  temperatures, cool soil temps, bright light, plenty of moisture and humidity (but not a saturated growing medium) during germination and vegetation may all influence a grower's number of females.

In Switzerland, where they were (briefly) able to grow large fields of psychoactive cannabis, they noticed that when Spring was warm, bright and moist, the result was a slight increase in the ratio of females.

This worked out to a few dozen extra females per thousand plants, but in the few years that such large scale grows were possible, the trend was consistent.
