Cream Caramel is BlueBlack x Maple Leaf Indica x White Rhino
Cream Caramel F1 Fast Version is exactly the same thing but with a shorter flowering time. The Cream Caramel was crossed with a 3rd generation autoflowering strain from the Sweet Seeds R & D department (that's where the gene came from) but the only characteristic gained is a faster flowering, all the rest in the same as Cream Caramel.
This is not an autoflowering or semi-autoflowering. This is a "conventional" non-autoflowering strain with a short flowering time.
Hope this helps a bit, hehe... thanks for the visit, sweet smokes
