Blue Dreamatic is Blue Dream mom and Tangie-matic dad. I just grew one out myself. All of my plants were smaller this run, so likely some environmental factor keeping them from full potential, but the flower is really good quality. Not as good as the Orange Sherbet, which is Tangie-matic mom and quite similar.
It grew well and did not show deficiencies that others in the same tent did. I recommend it, but Blue Dream was one of my favorite cultivars so I am a tad biased.
