alllllright..... you can supercrop anytime as long as the plant has atleast made a few internodes..... if your growing from seed i would start supercropping after about a month or a month and a half of growth.... and you can keep supercropping until 3 weeks into flower... but dont add more than a crack/bend per week ... so all in all, dont super crop a 2 month old plant more than 3 - 4 times.......... anymore questions let me know... peace out
