Hi. I have not used any method before so my opinion may be flawed.

From an outside perspective, not knowing whats in GA etc....

The safest way would appear to be Over Ripen. I think this because there is no chemicals used and if the offspring were to carry the trait it would be harmless to your crop. Because the flowers would come only after the time you usually crop them (so no harm done).
I think Heat Stress would be the worst possible way to force them.
