People in California who grow outdoors, say that there plants are always in 90+ degree weather without any ill effect. Just make sure they get plenty of water.

Yeah! I have, what do you want to know about it? Back in the day (before I knew you weren't suppossed to) I grew some bagseed, outdoors, in 5 gallon buckets. During "Full-on" Summer it hits anywhere between the "High 90's" and the low "One-teens" every friggin' day out here (Southern California - Inland Empire area). And that's with single digit humidity (at least, according to the digital weather station I got from Radioshack).

I started sometime in early Spring (don't remember exactely when) and they grew to about 2 - 2 1/2 feet tall before it started getting hot. Then they grew all through the Summer - up till about Halloween - and they never got much over 3 feet, or so! Once it got hot, they basically just quit growing, although they stayed green and healthy looking.

This was quite a few years ago (pre-internet, for me!) and I just used the "Heavy pot - Light pot" method of watering (with straight tap water no less!) but I remember watering them just about everyday through the hottest days!
