I've a couple of Kandy Kush x Skunk #1 from Sam, I popped one and it's not doing too good but I think that was my fault, as another plant has the same problem(it just never took off, perhaps not enough light).
The plant is healthy and looks nice, but it's just very short, about 12inches tall from the soil to the top. It's also in flower and barely stretched an inch, but the same thing happened to another seed at the same time from a different breeder(Dutch Passion's Durban Poison). But still, they'll yield a few grams and serve as testers, so it's all good.
