I'm with Stinky.....I'd do it with lighting and avoid giving the plant anything I didn't need to. That being said.....heck YEAH I'd do it to keep the genetics in play.
To force male flowers on a female, I've used Gibrellic Acid, ( ) Aspirin tablets, and light. Different grows, not at the same time.

GA has a tendency to burn leaf tissue when applied foliar, but works (strangely, some people freak-out just hearing the name) Aspirin or light poisoning work pretty good too.
I don't keep a record, but since starting doing it a couple of years ago, no discernable differences in quantity or quality of the resultant pollen, and seeds are somewhat consistent thru all mehtods.
Results: Perhaps 90% female, 10% weird females. Sometimes you'll get a plant that is confused about how many fingers her leaves should have, sometimes it's confused about how long the center finger on her leaves should be, sometimes internodal stretch is exaggerated or diminished...minor stuff like that, that altho looks funky, is still smokable. But no males. :thumbsup: If you got any males, it's from another non-hermied pollen source.

This is why it's likely not a good idea to breed a female from forced hermie stock. (don't breed the feminized plant if at all possible, unless it's an emergency or experiment) The genetics can go astray.
