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.
Rusty Trichome Reviewed by Rusty Trichome on . this one is for stinky! well lately it has been getting colder here but still hot in the days. i run my lights at night and have been opening the window letting all the cold air in.. When my light is on at 8pm-8am my temps start out at 80 then goes to 90 for an hour or so and they drop every hour down to 75.. when my light is off during day time i close my window and keep the ac at 75 in my house but my temps are around 78-80 my question is,, with temps like this are my plant going to go hermaphrodite? one Rating: 5
