serous seeds ak47,white russion,chronnic

Hey guys ive been looking at this seed company the strains look pretty good potency and yeild are the genuine in there seeds becuase there pricy but if there good ill spend the money dont want no hit and miss shit has any one tryed them flowering time and yield and potency

I haven't tried the Ak-47 but i have tried the White Russian which is a mix of Ak-47 and White Widow and i must say it was a powerful smoke I'm pretty sure it was the best weed I've ever had, i harvested it at 9 weeks and it yielded pretty good too about 3.3 o/z on my first grow, when i was harvesting i smoked a tiny bit of some scissor hash i got way to high, https://www.rollitup.org/toke-n-talk/593083-i-think-i-just-peaked.html
