Yield will be affected but one night of those temperatures wont be enough to kill a plant raised in the outdoors (ruggedized). True outdoor strains can be pretty cold resistant in short periodsit will for sure affect the plant... wont kill it(maybe?) any thing below 60-65 is not good. i had my a/c duct blowing right on one of my plants during the summer... it got cloudy and the house didn't heat up.. the plant was cold burned within a day and lower leaves were burned lookin
