I have heard from more than one reputable source that length of stone can be attributed to growing in soil and it being organic. The opposite is true for hydroponics which I have noticed created more of a creeper at first and then an short intense high. I had a buddy that ran hydro and mothered in soil. We had gotten accustomed to a certain high which was short. When he switched strains he flowered out the mother its buds high lasted much longer, which makes me believe that this theory is true, but the mother obviously had a much longer veg time as well so that may be a factor too.
just my 2 cents
