Got to tell you... My experience is different from the previous poster.
In the autumn.... I dig my mature pepper plants out of the garden... Pot them up and keep them in a sunny window.
They go dormant. I pick the peppers as needed, and eventually... In february, or so... The plants come out of dormancy and start putting out new leaves and blooms, and the dropped peppers start growing litte baby pepper plants...
I failed to set out one of my pepper plants this year... It's still in the pot (outside), and there is little pepper plants coming up in the pot! So...
Yeah, how good are yer plant lights?
