Stretch was fast in weeks 2 & 3 to the point I LST,d top 2 feet. Week 4, good internode between buds and yes plenty of bud sites . Buds were smaller than I would have liked but they were very hard good quality the hole plant turned deep dark purple with my masses of trichomes. No issues with in growing this strain will grow again as excellent for the couch yeah very nice not to difficult to grow either. Roughly 5 Oz per plant. Easy to grow beautiful colours.
