Answer: Tomatoes need about 8-10 hours minimum of sunlight per day. They like heat up to a certain point. (Over 90 degrees and their pollen is no longer viable.) If they continue to look healthy, don't worry about the temp. If not, you might want to provide some nighttime protection for them, particularly if the temps. in your sunroom drop. When flowers appear, gently "tap" them in the morning to pollinate. Unless you are also keeping bees in your sunroom! Good luck!
