Blueberry and BlueberryBlast runts, especially if the leaves look like they were dipped in acid, were some of the absolute best smokes.
I find super vigorous plants to have a masculine quality while runts and late-bloomers have a more feminine quality
I also find that when people select only for the most vigorous and first-to-flower plants to breed with, the end product after a few generations is bland, one-tome high and lowered potency.
