About Grapefruit Superstar

Amsterdam Genetics built this sativa from Grapefruit and Superstar parent lines, keeping the mix at 80 percent sativa to 20 percent indica. It's rated a moderate grow, flowering over 9 to 10 weeks and finishing indoors between 80 and 140cm, with yields landing in the 400-500 grams per square meter range. THC testing reaches up to 20 percent. No outdoor figures, effects, flavors, or terpenes have been documented for this particular cut, so the lineage and the indoor numbers are what growers have to go on. For a moderate-difficulty sativa with a two-strain pedigree behind it, those grow specs alone give a fairly clear picture of what to expect from a tent or grow room setup.
