I've actually read about experiments involving "feminizing" seeds by using bananas... The idea is this: As bananas ripen, they emit ethylene gas. Exposing the seeds to this gas should, theoretically, cause the percentage of females to be increased.

Search it out in Google or some other search engine.. There are some pretty interesting reads on the subject.

Ethylene to produce females If ethylene is a known plant hormone to determine sex in cannabis couldn't I put a bunch of ethylene producing fruits near my plants and hope they all turn female (When they are from seed) that's probably not enough Ethylene what if you theoretically had a Ethylene spray and you sprayed your plants?
