Cheers Old Frog,
Many moons ago I found a purple Shiva Skunk which is pretty rare, I crossed it with the best looking purple Black Russian male I had. In the resulting seeds I grew out all the females and 24 males and crossed what I thought were the best females with the best males, later I found a purple Shiva Skunk male which has also been used in a separate breeding programme of the Black Rose. I have carried on doing this over recent years until the latest F6 generation. I have selectively bred the plants to be purple regardless of temps and to be a potent smoke with a nice taste.
So you can see this is a long term breeding programme which I will keep at until I am completely happy with the results.
Heath
