Minimum nighttime temperature for seedlings
I have a lot of tomato seedlings that I just transplanted from my seed starting trays into individual 4 inch pots. As a result I don't have room for them anymore under my indoor fluorescent light. So I have been taking them outside during the day and bringing them back indoors at night, but not putting them under a light. This is getting old in a hurry. What is the minimum outside nighttime temperature at which I can just leave them outside all the time. Right now in my part of southern California the minimum nighttime temperatures are in the low to high 40s, but I am worried about what if we drop into the high to mid 30s.
