Polar is now 21 " and weighs around 40 lbs, im sure he will gain more weight as he gets older but id like to know if he has finished growing height wise? And if not when will he.

Polar should finish growing around 2yrs. he will slow down somewhat around 1 but will keep going till about 2 when he will start to fill out.

Ghost is ~21" and 42 lbs, and is only about a week younger than Polar. I think she's going to be a big girl...

They grow 95% in their first year. After a year they won't get much taller, just start filling out.

I think there's a thread about this somewhere, but I'll repeat:

We've gathered information from across boards and it seems that generally, huskies will grow fairly steadily until 7-10 months of age in height and weight. After that they plateau for a while before hitting another spurt around 15-18 months. They might grow a bit more in height at that time, but they will definitely begin to fill out from then until they are at least 2 years old. Some huskies even continue to grow until they are 3.

To give you an idea, at 7 months old, Koda was about 22" and 45lbs. He is not 23.5" and 60 lbs at 5 years old (yes, I missed another birthday. I'm an awful momma, lol).
