Yes, heat is one way to stress your plants into hermaphrodism, but no...it's not a good way to do so. (for those that stress for femmed seeds)
Any excessive stress can cause hermies, whether it's light stress, chemical stress, over-ripening, heat-cold treatments, silver colloidial treatments...

If you are not experienced with growing cannabis, and there are existing stresses from improperly administered nutes, ph fluctuations, improper soil chemistry, overwatering... (just a couple of the common causes of stress) it doesn't take much heat to push the ladies over the edge, and throw-out some nanners.

As one that is forced to grow in intollerable conditions (in the desert, outdoors shed) I do not recommend arbitrarily telling someone that excessive heat is ok, as it's not. Unless you understand how to properly deal with it and have no other viable alternative...best to keep the temps within 'normal' ranges.
