In that case I would expect longer than 10 weeks of 12/12.My plants are Green Crack Punch - combination of Green Crack and Purple Punch.
This variety received its 60% sativa dominance from Green Crack and the 40% indica side from Purple Punch.
you may be lucky and have a fast finishing phenotype.
On the other hand you maybe unlucky and get a recessive sativa trait that takes 15 weeks or more.
it depends how the stability has been done with the back crossing etc and how they have been breeding in the traits they want to lock down.
Or whether they’ve just got a Green Crack Male, Purple Punch female and then pollen chucked and sold the resulting seeds.
