purple urkel or big bud

I got a seed out of some grand daddy purp(big bud crossed with purple urkel) and I was curious what seed it would be....big bud or purple urkel...it wouldn't actually be a grand daddy purp seed cause I'm not sure if thats possible.

you'll have to grow it out to know which pheno it is.

Grow it and let us know how it turns out. Take lots of pics
