Were the plants affected badly with those temps?
I'm just guessing here, if you think about the plants origins they're most likely from warmer climates, i,d expect any problems at higher temps to be water/feed related.
Here in the uk it can/does hit 40⁰c on a good day, thats in direct sunlight, our weather data is recorded from shade, idk how different ambient is versus direct but plants are withstanding 40⁰c and more regularly outside your door if you put out a thermometer you'll see it.
I'm going to guess they looked ok?
@Fish scale hey bud how did your plants look with those warmer temps you had?
