Ideal Growing Temperatures

Ideal temperatures for growing tomatoes are above 70 degrees daytime and 55 degrees nighttime, and below 95 degrees daytime and 80 degrees nighttime.

A 15 degree differential between daytime and nighttime temperatures is best.

Temperatures outside the above ranges will substantially reduce or stop fruit-set and also contribute to other problems, such as cat-facing, blossom-end rot, etc.
