Gibberellic acid for all female seed.

[Outlaw]

I read that spraying 100ppm of gibberellic acid on a female branch once a day for 10 days will turn it male but because the plant is female it will have female chromosomes. Crossing the pollen with another female from a different mother will then create all female seed without risk of inbreeding. Does this work? Would save a lot of water carting if I could make my own all female seed.
