I had great success with "Utopia haze", it stayed shortish and yielded pretty well for a sativa. Doing chocolope now and WOW so much plant in so little time!!! Be wary with any sativa, as they really like to stretch once they hit 12/12 (Chocolope is no exception). I will say tho, the Utopia haze had a really good buzz, even if it took a month or so longer to finish than anything else I had at the time. If grown tree style (utopia haze) expect BIG main cola's!!
