Skywalker is a popular strain across the United States, a hybrid with an even 50:50 sativa/indica ratio. Its THC levels top off at about 15 percent, making this an average to below-average strain in terms of potency. But it makes up for that with its mellow body high and mental clarity, plus a pleasing aroma and flavor. It’s a cross of Blueberry and Mazar-I-Sharif, both famous strains in their own right.
