Inside, with even a decent cheap flourescent they will go year round, peppers are perrenials, not annuals.Many grow them as annuals, but in their nat. habitat , they rock and roll all year long
!
The yellow is probably a yellow seven, you won't see the dimples and gnarliness a sun grown plant will produce, nor probably the same heat level.
The tips of the pods are the weakest, and the crown w/placenta as Greg said is the fiery end.The Choc habs are kinda middle of the spectrum heat wise- but they are one the most "useable"-you will find after you build up to eating warmer stuff, that you can eat them alright WITH food-and that is the real point after all.
Glad to see you stickin with the fight-its really cool to see they made it to podding and ripening for you indoors with no lights...+1 for sure.That rocks!
