I live in the desert(Mojave) of southern California hot as shit out 100 every day easy, i water them once a day at night right after sun down i let them drip until i see the excess draining out of the drain holes?
damn 100 id put it in the ground the ground, soil has to be cooler then the bucket, you can get some issues if you over water like root rot or just flushing out all the food
*~* i got a plant in a bucket that does not like it at all way to hot for it, been over 100 for like 2 weeks now here
if you cant put it in the ground then i would just try and let the bucket dry out before you water it, do a weight test (water it and pick it up see how heavy it is, wait till your plant wilts and pick it up and feel how heavy it is then never let it get that light again)
*random info* a guy i know grew in your area in sandy soil with GH floral series and well water one plant produced about 7lb, he can grow very well he taught me about pH and how it being off by .2 can reduce your yield significantly
