Only way?? No, THE way. Stress during flower causes herms. Stress during veg may also cause herms.

Advil? Please don't post bad info. The active ingredients in aspirin and advil are NOT the same. Salicylic acid has been used to force-herm females into producing feminized 'S' generations... most growers will never want to do this, and photoperiod stress is the generally accepted way to do it anyway.
