first off drchronic.com has a lot of joint doctors stuff but ive done lowryder 1, lowryder 2, diesel ryder, and snowryder and i would say go with the lowryder 2. trust me it will blow ur socks off, and u wont believe how fast and easy it is too grow. use 20/4 lighting. lets put it this way i started 4 strains one being lowryder 2, and the lowryder 2 was forming buds before the otheres were even ready to flower, good luck brotha
