The only uk clone that I know of thats made the trip across the pond is the cheese that supposedly Jason King brought back in 04, its legit cheese and a great outdoor strain...in fact its much better outdoor than inside but that may be due to age. Strains have a difficult time just going north of us to Canada and vice versa as there are quite a few canadian clone only strains that i have not seen anywhere in the states, I assume its the difficulty and risk associated with sending clones. I can tell you that I would love some of your uk clone only strains in the states, as I have been lucky enough to know that the best indoor growers in europe are in the uk and there are some amazing flavors there. If you have access to all the old school uk strains it would be amazing to see a detailed thread on everything. Our U.S. clones are actually pretty easy to obtain if you are stateside as one could easily go to harborside and buy dhn clones and get most of the clone only cuts that circulate cali.
