As I understand it, White Russian came in at 23% (indoor hybrid - 50%-50% or thereabouts). If you've ever smoked the stuff, you'd believe it, as you're on the floor after one hit. Also, the high is IMMEDIATE. Very smooth, and a very up high...puts an instant smile on your face. P.S. the seeds are on the expensive side (you probably know this - $95 pk. from SeedsDirect), but well worth it. Huge buds, & clone very easily.
