I tried to produce tomatoes both inside and outside in Juneau, Alaska, where the summers provide more than 12 hours of sunshine on those rare occasions when the sun shines in that temperate rainforest. Although I could get tomatoes, they would never turn red because even sunlight was just not strong enough. I produced them indoors under a halogen lamp, and they were red and sweet, but they never got very large, no matter what variety they were. It seems full sun is an absolute requirement for the love apple. Linda Kuczwanski
