AsNoriuanswered grow question 3 years ago In my last auto run I had temps in high 40 cel and humidity at 20-40 % all ended up good. And lasted for few weeks, here only 4 hours, girls are far in flower, so in nature it would be just a hot midday ...
Keep an eye on balls forming, such thing can be stress for them, but generally if you brought humidity, air circulation to normall - you are more than safe !
Good luck !
