Hey Bob, I'd put the duration at more than 2 hours and very strong potency. I've grown both Sour Bubbly and Ripley's OG from Mephisto. Ripley's has a 2+ hour stone...anything above 1.5 hours I would say is above average. I like the Ripley's very much in fact, still smoking her, and she has good med effects but I feel Stone Dragon is much better at alleviating pain...not to take anything away from Ripley's, it's a great strain too. I don't know I've ever heard anything negative about Mephisto gear, and same for Stone's gear...many more from both that I'd like to try. Stone provides nice freebies as well, I don't think you'd be disappointed with the quality. If you are seeking to relieve pain, aches, nerve pain or insomnia, I think you'd be happy to try Stone Dragon, I'd put it up against anything, auto or photo, as far as medical effects are concerned. A+ strain. You can see how I did with both the Dragons and Ripley's in my garden of Goodies thread.
Here's my jumbo purple pheno, got 4 oz + 15g of completely dense, solid buds off an 18-19" tall plant.
