It doesn't appear to be. The Fast Buds site doesn't share the genetics other than it's an LSD bred with an auto flower. However, looking up LSD: Mazar-I-Shariff (indica) x Shunk No.1 (hybrid). Where as MK Ultra: OG Kush (hybrid) x G13 (indica). MK Ultra does sounds interesting though. I might have to put it on my wish list for future grows.
Beez, you know why I asked that question?
