Plants generally grow between 2 and 3 times as large in flower as they are in vegetative state. Being that those are both indica varieties, they *shouldn't* stretch much. Assuming this is the case, you can tentatively plan on between 4 and 5 feet tall. I would personally estimate more on the lower end, the strains being what they are. If I'm wrong, someone feel free to correct me.
EDIT: One thing I forgot to mention is that height doesn't necessarily equal yield. So really it begs the question, are you asking how tall they might be? Or how much they will hypothetically yield. If it's the latter, there are far more factors involved, the least of which is the genetics and phenotypes of each individual plant. Were these grown from seeds, or from clones?
