Sin city has straight fire and blue power is there top selling strain I believe a lot of people say the blue power is the best in there lineup, I've had BP, night fire og, aliens jackd up, and power nap and all are fire my fav were BP and aliens which is sour alien x sour jack. The powernnap was right there too just it was similar to BP probably because its in the x. Then again powernnap we had the least of so we probably just had some BP leaning phenos. Sin city has quickly become a top breeder of mine and I didn't have any germ issues, if your having germ problems grab a gallon of distilled water and a spray bottle a bowl and flat plate not clear, and a couple of labeled cups, boil some distilled water, rinse everything out with peroxide, then pour boiling water over everything make sure ur hands are clean, then I rinse out one more time with distilled. Grab a new roll of paper towel only white. Cut 6 3 inch by 3 squares out put on plate and cover with bowl. Now add distilled water in cups labeled for strain only a couple inches. Let sit for 7 hours no more or less it starts to penetrate and activate the beans then put in middle of 3rd sheet of paper towel put other 3 on top, mist with distilled water not too much is needed just keep lightly damp and don't let dry out, put dish on top of cable box for some heat and ur ready to go, u should get close to 90 percent germ rates. Whenever u check them make sure hands are clean with hand sanitizer actually make sure ur hands are always clean with sanitizer especially when u touch paper towel or sprouts. Wait for them to grow little tail use pinky poke a little hole in soil not too deep put taproot facing down and cover shell with a very little bit of soil to help shell break off and ur set.
