I have 5 potted pepper plants, some are flowering a second time and some are fruiting their second time. The temperatures outside are in the 60's and the lows are in the 40's. I want to get this second crop. The plants are around 2 foot tall. When should I bring them inside? I also have 2 lights to put on them to help them out. What do you think? Here is a pic of the box I got the lights in.
