What is the ideal nutrient solution temperature range? What happens if the temperature goes over or under the ideal temperature range?

Print this and read it. As you can see, above 20C (68F for the metric challenged), oxygen solubility falls way off. The more oxygen you can get to plant roots the better.

Thanks for the chart Willard...This was one of the things I was worried about when growing outdoors in the heat of the summer using my aeroponic chambers. So far so good, I always supply extra oxygen via large airstones in each growing chamber. A large airpump works well to supply a constant airflow and on the very hot days I freeze large gatoraid containers, etc filled with water and drop them in the reservoir to keep it cooler.

Overall, things keep growing even when the temps get above 80 in my reservoir, although it's not optimal I was worried about my plants dying, and so far so good.

Thanks for the chart!
