Ive never heard anyone say jack herer sucks. OTMS might be great but never heard anything about it. I would say go for the Jack, find a momma and clone the hell out of it. Or cross it with a nice indica to bring down the flowering time. I wanted to grow out JH but didnt really feel like droppin the coin for it, so i went with Jock Horror instead. Thats another strain that ive heard nothing but good about. And its cheap aswell.
