Although Sativa strains tolerate heat well, no cannabis plant will thrive in extreme heat. Temps. over 90-100 degrees will stress the plant and thus effect yields and the overall health of the plant.
I suggest getting a baseline temp. of the area you intend to grow in before starting any plants. This will tell you if the area is even suitable for growing.
