you're probably looking at a month-and-a-half or more but i kinda doubt if the ones that are developing now will ever amount to much. i don't know why but the stragglers that come up after the main vines are trained usually never seem to develop properly. i figure the daylength, temperatures and other factors are at work here. right about the time the days start to get shorter, most of the vertical growth is just about done and the plant begins to transfer a lot of energy into cone production. once the brunt of the cones are ripe, i would figure the majority of the carbohydrates produced are being sent back down to the crown to keep it healthy for next year. my 2 centsworth.
