No, probably has similar parentage, but blue dream (clone only) is a clone only strain from California. It has made its way North to Washington and east to Colorado, but I'm not sure if you can get the clone only anywhere else at the moment.
From my experience finding a legit clone only strain on the east coast is a huge fail. I've never even smoked blue dream. But maybe it's because i live in the sticks. I do have some HSO blue dream but it's not the same
There are plenty of "legit" clone only strains on the East Coast. Im holdin the GG#4 clone only cut.
You must really live in the sticks. Blue Dream floods the market by the ton every year.
I think you just need to get out more.
