First time growing Serrano peppers.
I have grown Cayenne in the past, which I always wait to turn red before I pick so they are at their hottest.
I have also grown Jalapenos, which I always pick BEFORE they turn red because I heard they were hottest when dark green.
So... which way is it with Serrano peppers? Are they hottest when green or when red?
Also, will they get the vertical stripes/striations like Jalapenos do?
